The workaround is to reduce the number of changes to the password in the console or VTY when the relayed console waits for the authentication prompt. The issue occurs after reloading the stack members or after online insertion and removal OIR of the transceivers that are DOM capable. The sh env fan command does not detect faulty power supply fans on a switch.
When the source starts sending traffic to the multicast group, an S,G is created and some of the initial packets sent by the source are lost. Once the S,G is programmed for the traffic sent by the source, all the subsequent multicast traffic reaches the receiver.
This issue takes place only in stack configurations. The workaround is to use vrf definition command instead of ip vrf command to configure per-VRF. After performing a shut or no shut on the ports of a Catalyst Switch, the status of some of the ports are displayed as Not Connected , even if they are connected to a remote device.
The workaround is to perform a shut or no shut on the affected ports. The switch reboots if the shutdown and no shutdown commands are repeatedly entered for the alternating ports in an 8-node Resilient Ethernet Protocol REP ring segment. The following error message is displayed:.
The workaround is to bounce the forwarding REP port on the switch stack. The workaround is to downgrade the switch to When you repeatedly run the shut and no shut command in the alternating ports on a 8 node REP ring, the stack member with REP secondary edge port drops the multicast traffic for 20 to 50 seconds. When IPV6 MLD Snooping is enabled on a switch and the switch is restarted, the packets that are destined to Solicited-Node multicast address are not forwarded in some rare instances.
This feature, which previously showed errors, is now functioning properly. As a result, connectivity is not possible even though the client machine has a valid IP address, and dACLs downloadable ACLs are not applied on the interface.
The workaround is to configure authentication as open so that traffic is allowed only after authentication is successful. If the channel goes down, there is no message output displayed on the stack switch. Netflow cache is not created after applying a flow monitor to the interface on the member switch. The workaround is to either disable multicast fast convergence or configure IGMP version 3 on switch virtual interface.
The workaround is to enter a shutdown command followed by the no shutdown command on the ports of the service module. The workaround is to enter a shutdown command followed by the no shutdown command on the port. CTS environment-data download failed on non-seed device after reboot. The workaround is to check if the displayed VLANs are internal and then to hide them. The workaround is to implement SNMP view using the following commands:.
As a result, egress traffic to another router on an SSH connection is blocked. The device connected to the switch crashes when a CDP data frame is processed. The workaround is to disable CDP using the no cdp run global configuration command. This workaround is not applicable if the connected device relies on or supports a phone or voice network.
The workaround is to apply protocol filters to the device sensor output by entering the following global configuration commands:. Spurious traps observed periodically on removal of power to RPS. STP loop occurs on Flexstack connected by parallel links when a link state is changed on Flexlink port. The workaround is to change the switch to root bridge. The traffic continues to take failed PBR path instead of the next available best path.
On running show interface command, incorrect value is displayed in input error counter. You can ignore the results of on-demand diagnostics if POST succeeds on boot up. The configuration recovers automatically. If a policy map attached to the switch interface is modified then the corresponding QoS policy works incorrectly. The workaround is to delete the policy map, create a new policy map and then attach it to the interface.
This issue occurs when the WCCP cache engine is shut down and the cache is not cleared. When native VLAN is configured on the trunk or when switchport trunk native vlan 99 is configured on the interface, spanning-tree instance is not created for native VLAN. The workaround is to keep VLAN1 as a native on the trunk. To disable dot1x internally, run the no macro auto monitor command. The stp instance is created for native vlan 99 after running the show and no show command on the interface.
The workaround is to remove the WCCP redirects command from the interface and then add them back on the interface. On the Catalyst S switch stack, when the login block command is configured and the running config is saved using the wr command on the master, it makes the master down.
When the running config is saved on the new master, the following lines are displayed on entering the show running-config command. When the secret password is configured, the password is not saved. The default password is used as the secret password. The workaround is to use the default password to login and then change the password.
A vulnerability in the Service Module could allow an authenticated, local attacker to gain root access to the kernel running on the Service Module. The attacker can use the default credentials to log on to the Service Module and take complete control of the operating system running on the Service Module. This symptom is observed in Cisco IOS The known workaround is to enter the no service dhcp command if the switch is not a DHCP server and configure the device sensor as follows:.
The work around is to perform any of the following action:. The suggestion is to make less use of the show macsec int command on the interfaces when SFP is not present. When reloading a switch in a stack that contains a service module inside a member switch, the links on the service module does not show up after reloading the member switch.
The known workaround is to restore the link by entering shut and no shut commands on the ports in the service module. When a client fails to authenticate in the multi-auth mode, the session continues to be active indefinitely. The workaround is to enter the clear authentication sessions privileged EXEC command to clear information for all authentication manager sessions.
The down-when-looped interface configuration command is not supported with default speed or with BaseT advertisements on the gigabit medium independent interface GMII interface. This is because the down-when-looped feature and BaseT advertisements both make use of the "next page" function as defined in IEEE This delays the switch boot time. This behavior is also seen when using the force-ucode-reload option. FRU Power Supply is not responding. This message does not indicate a hardware failure of any kind.
Cisco has released free software updates that address this vulnerability. There are no workarounds available to mitigate this vulnerability. The Cisco IOS Software implementation of the virtual routing and forwarding VRF aware network address translation NAT feature contains a vulnerability when translating IP packets that could allow an unauthenticated, remote attacker to cause a denial of service DoS condition. Workarounds that mitigate this vulnerability are not available.
When two traps are generated by two separate processes, the switch fails if one process is suspended while the other process updates variables used by the first process. If a redundant power supply RSP switchover occurs during a bulk configuration synchronization, some of the line configurations might disappear. The workaround is to reapply the line configurations.
This restriction has been removed, and several IP addresses can now be mapped to a single MAC address. The show ip dhcp pool command displays a large number of leased addresses. The workaround is to turn off ip dhcp remember and reload the switch. The secure copy feature copy: source-filename scp: destination-filename command does not work. NetFlow Data Export NDE packets might be dropped when virtual routing and forwarding VRF is configured on the switch and the exported traffic has conflicting information from the VRF tables and the routing information base.
This problem occurs when the Enterprise Policy Manager EPM for a device connected to an interface is authorized in closed mode and no policies are configured or downloaded. If another device is connected to this device, restricted VLAN authentication event interface configuration command is enabled on the port. The workaround is to perform the following actions:.
When the ip rsvp snooping command is enabled on a Layer 2 environment, the switch stops forwarding the metadata packets. When the master switch Switch A is reloaded or loses power and rejoins the stack as a member switch, any traffic stream that exits Switch A is dropped because the newly joined member is not able to establish an Address Resolution Protocol ARP entry for the next hop router or switch. The workaround is to add a static ARP. Local web authorization and HTTP services on the switch do not respond because of a web authorization resource limitation in the system.
These are possible workarounds and are not guaranteed to solve the problem:. After reconfiguring the flow monitor in the switch interface, the show flow monitor shows that NAM3 is active. The workaround is to reconfigure the flow monitor in the switch interface. The macro is applied to devices such as PCs, laptops, and printers. You do not need to configure MAC operationally unique identifier OUI -based triggers and map these triggers to a macro for these devices.
The Smart Install client feature in Cisco IOS Software contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service DoS condition on an affected device. Affected devices that are configured as Smart Install clients are vulnerable. There are no workarounds for devices that have the Smart Install client feature enabled.
The SAP preshared key configured for Cisco TrustSec manual mode is saved and displayed in the configuration file as clear text. Heavy traffic load conditions may cause the loop guard protection function to be automatically activated and almost immediately deactivated. These conditions can be caused by entering the shutdown and no shutdown interface configuration commands or by interface link flaps on more than forty ports.
These log messages appear:. When quality of service QoS is disabled on the switch, fragmented IP packets that are sent to the switch are queued in the wrong egress queue Queue 1. This situation causes a high number of output drops since the default buffers for Queue 1 do not have the capacity to handle data traffic. The workaround is to enable QoS and modify queue buffers. This leads to a convergence time of more than 5 seconds.
The problem appears under these conditions:. This problem has been fixed now. No action is required. When you configure and save the monitor session source interface, the configuration is not saved after reboot. A bidirectional port on a stack member returns an incorrect status. The workaround is to reconfigure the Cisco TrustSec link layer security.
You can do this in the When traffic is routed between two VLANS, multicast packets on the switch are lost for a few seconds. This happens only when the multicast source routes traffic to a group that already has a receiver on it. When you configure FlexLinks on the service modules and you plug the link into the port, the following syslog error message appears repeatedly:. If an interface is configured with the switchport port-security maximum 1 vlan command, the following error message is displayed:.
The flash memory is corrupted when you format the flash manually. The workaround is to reload the switch. If the Performance Monitor cache is displayed using the show performance monitor cache command and you attempt to stop the command output display by entering the q keyword, there is an unusually long delay before the output is stopped.
The workaround is to enter the term len 0 privileged EXEC command so that all command outputs are displayed without any breaks. There is a memory loss when routing entries are updated in the table, because the switch is not releasing previously allocated memory when system resource allocation fails. After a master switchover on a switch stack, IPV6 multicast routing fails. The workaround is to avoid configuring IPv6 multicast routing on larger stacks.
We recommend enabling IPv6 multicast routing on stacks with five or fewer members. When the show epm session summary or show epm command is entered from an SSH or telnet session and another command is entered from the console, the switch might unexpectedly reset and generate crash information.
The switch might occasionally reload after experiencing a CPU overload, regardless of what process is overloading the CPU. A Catalyst X or X switch port might stop forwarding traffic. The packet counters increment for sent packets, but not for received packets. The workaround, to bring up the port, is to save the configuration and to restart the switch. The switch downloads the running IOS image from the TFTP server and reboots even though the same image is currently loaded and running.
An attacker could exploit this vulnerability by sending a crafted request to an affected device that has the DHCP version 6 DHCPv6 server feature enabled, causing a reload. This advisory is available at the following link:. When an interface is configured with the mls qos command, traffic is not matched by port-based QoS ACLs that use the range option.
The workaround is to is to configure the switch using the single port eq keyword. Alternatively, you can configure the trust under class-default setting for the same policy-map that uses the acl-range option. In a switch stack, you cannot establish a console session with a member switch when an ACL is applied to the VTY lines. The workaround is to use the following procedure when you apply an ACL to line vty 0 4 and line vty 5 Create the vty ACL and permit the network.
Append the vrf-also keyword to the configured access-class inbound. In a switch stack, the show interface command shows incorrect values for output drops. The workaround is to use the show platform port-asic stats drops command to see the correct values. A static route that has the next hop set to null0 is removed when the master switch is changed in a switch stack configuration.
This situation occurs when the switch is stacked and the static route is advertised by the network 0. The workaround is to use the ip summary-address eigrp as-number ip-address mask command to set the IP summary aggregate address for the interface through which the next hop can be found. When a device is moved from one port to another in a switch stack, the SNMP data generated for the move event is incorrect.
Users connecting to the network through a device configured for web proxy authentication may experience a web authentication failure. Using the dot1x default command on a port disables access control on the port and resets the values of the authentication host-mode and authentication timer reauthenticate commands to the default values. The workaround is to avoid using the dot1x default command and set various dot1x parameters individually. You can also reconfigure the parameters that were changed after you entered the dot1x default command.
The workaround is to flap the ingress physical interface, the SVI, or the port channel. In a switch stack setup after you reload a member switch, a multilayer switching MLS class of service CoS configuration command with a specified value such as mls qos cos 7 on the slave switch does not function anymore. This situation impacts untagged IP and Layer 2 packets. The workaround is to ensure that when you configure a service policy on an interface, an interface default level CoS is also configured.
You can use mls trust qos cos command in interface configuration mode. When using the switchport port-security maximum 1 vlan access command, if an IP-phone with a personal computer connected to it is connected to an access port with port security, a security violation will occur on the interface. This type of message is displayed on the console:. The workaround is to remove the line switchport port-security maximum 1 vlan access.
The switch does not correctly detect a loopback when the switch port on an authenticated IP phone is looped to a port configured and authenticated with dot1x security, even when bpduguard is configured on the interface. This situation can result in percent CPU utilization and degraded switch performance. The workaround is to configure the interface with the authentication open command or to configure authentication mac-move permit on the switch.
The Catalyst E series switch with Supervisor Engine 7L-E contains a denial of service DoS vulnerability when processing specially crafted packets that can cause a reload of the device. The workaround is to save the configuration and reload the switch. Alternatively, configure the switch by entering the no macro auto monitor command followed by the macro auto monitor command after the port is bundled for the first time.

Cluster Compatibility You cannot create and manage switch clusters through the device manager. When creating a switch cluster or adding a switch to a cluster, follow these guidelines: When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch.
If you are managing the cluster through Network Assistant, the switch with the latest software should be the command switch. The standby command switch must be the same type as the command switch. For example, if the command switch is a Catalyst X switch, all standby command switches must be Catalyst X switches.
Deciding Which Files to Use If you have a service support contract and order a software license or if you order a switch, you receive the universal software image and a specific software license. Table 4 Software Images Image. To download software, follow these steps: Step 1 Use Table 4 to identify the file that you want to download. Step 2 Download the software image file: a. Installation Notes Use these methods to assign IP information to your switch: The Express Setup program , as described in the switch getting started guide.
The CLI-based setup program, as described in the switch hardware installation guide. The DHCP-based autoconfiguration, as described in the switch software configuration guide. Manually assigning an IP address, as described in the switch software configuration guide.
The all keyword is now removed from the timers throttle lsa global configuration command. The vstack startup-vlan command has been added. For more information, see the command reference on Cisco. For more information, see the Implementing IPv6 Multicast chapter of the software configuration guide on Cisco. For more information, see the Cisco TrustSec chapter in the software configuration guide. REP is a Cisco proprietary protocol that provides an alternative to Spanning Tree Protocol STP to control network loops, handle link failures, and improve convergence time in ring topologies.
REP controls a group of ports connected in a segment, ensures that the segment does not create any bridging loops, and responds to link failures within the segment. Support for stack power is now extended to the LAN Base license. Catalyst X and X switches Support for port security on Etherchannels. For more information, see the Configuring Port-Based Traffic Control chapter in the software configuration guide.
Catalyst X and X switches. Minimum Cisco IOS Release for Major Features Table 5 lists the minimum software release after the first release of required to support the major features on the switches. Limitations and Restrictions You should review this section before you begin working with the switch. Address Resolution Protocol The switch might place a port in an error-disabled state due to an Address Resolution Protocol ARP rate limit exception even when the ARP traffic on the port is not exceeding the configured limit.
This could happen when the burst interval setting is 1 second, the default. CSCsh When switches are installed closely together and the uplink ports of adjacent switches are in use, you might have problems accessing the SFP module bale-clasp latch to remove the SFP module or the SFP cable Ethernet or fiber. Use one of these workarounds: — Allow space between the switches when installing them.
This is the expected behavior based IEEE CSCse When there is a VLAN with protected ports configured in fallback bridge group, packets might not be forwarded between the protected ports. CSCsh When line rate traffic is passing through a dynamic port, and you enter the switchport access vlan dynamic interface configuration command for a range of ports, the VLANs might not be assigned correctly.
CSCsz Catalyst X or X switches When the switch flash memory has less than 6 MB free space, there is not enough space in flash memory to hold temporary files created as part of a microcontroller unit MCU image upgrade, and the upgrade fails. The device-sensor accounting global configuration command is not available on Catalyst series switches. This occurs when: — The EtherChannel is a cross-stack EtherChannel with a switch stack at one or both ends.
Use one of these workarounds for ports in this error-disabled state: — Enable the switch to recover from the error-disabled state. CSCse When a switch stack is configured with a cross-stack EtherChannel, it might transmit duplicate packets across the EtherChannel when a physical port in the EtherChannel has a link-up or link-down event. This can occur for a few milliseconds while the switch stack adjusts the EtherChannel for the new set of active physical ports and can happen when the cross-stack EtherChannel is configured with either mode ON or LACP.
This problem might not occur with all link-up or link-down events. IEEE When IEEE CSCsd When you configure the ip igmp max-groups number and ip igmp max-groups action replace interface configuration commands and the number of reports exceed the configured max-groups value, the number of groups might temporarily exceed the configured max-groups value.
No workaround is necessary because the problem corrects itself when the rate or number of IGMP reports are reduced. CSCse When you configure the IGMP snooping throttle limit by using the ip igmp max-groups number interface configuration on a port-channel interface, the groups learned on the port-channel might exceed the configured throttle limit number, when all of these conditions are true: — The port-channel is configured with member ports across different switches in the stack.
When the same loopback cable is connected to a non-PoE port, the link becomes active and then transitions to the error-disabled state when the keepalive feature is enabled. The switch does not respond to power requests from the other protocol. If CDP is disabled after the switch has locked on it, the switch does not respond to LLDP power requests and can no longer power on any accessories.
QoS When QoS is enabled and the egress port receives pause frames at the line rate, the port cannot send packets. CSCsd If the ingress queue has low buffer settings and the switch sends multiple data streams of system jumbo MTU frames at the same time at the line rate, the frames are dropped at the ingress. CSCsd When you use the srr-queue bandwidth limit interface configuration command to limit port bandwidth, packets that are less than bytes can cause inaccurate port bandwidth readings.
The accuracy is improved when the packet size is greater than bytes. CSCsg If QoS is enabled on a switch and the switch has a high volume of incoming packets with a maximum transmission unit MTU size greater than bytes, the switch might reload. Use one of these workarounds: — Use the default buffer size. Routing The switch stack might reload if the switch runs with this configuration for several hours, depleting the switch memory and causing the switch to fail: — The switch has Open Shortest Path First OSPF neighbors.
Smart Install When upgrading switches in a stack, the director cannot send the correct image and configuration to the stack if all switches in the stack do not start at the same time. A switch in the stack could then receive an incorrect image or configuration.
CSCte Backing up a Smart Install configuration could fail if the backup repository is a Windows server and the backup file already exists in the server. CSCte In a Smart Install network with the backup feature enabled the default , the director sends the backup configuration file to the client during zero-touch replacement.
However, when the client is a switch in a stack, the client receives the seed file from the director instead of receiving the backup configuration file. CSCtf If the director in the Smart Install network is located between an access point and the DHCP server, the access point tries to use the Smart Install feature to upgrade even though access points are not supported devices. The upgrade fails because the director does not have an image and configuration file for the access point.
If the client switch does not have a configured password, there are unexpected results depending on the software release running on the client: — When you select the NONE option in the director CLI, the upgrade should be allowed and is successful on client switches running Cisco IOS Release Catalyst X and X switches When you enter the show monitor privileged EXEC command the monitor source port output is incorrect. This situation occurs only if the monitor source port s is a pluggable Gigabit module and you set any source port combination, except when just using a single Gigabit port on the pluggable module as the source port.
CSCsx Where there is a mixed hardware stack with Catalyst X or Catalyst E and switches as stack members, when you change the configuration and enter the write memory privileged EXEC command, the unable to read config message appears. CSCsd When using the logging console global configuration command, low-level messages appear on both the stack master and the stack member consoles. CSCsd If a new member switch joins a switch stack within 30 seconds of a command to copy the switch configuration to the running configuration of the stack master, the new member might not get the latest running configuration and might not operate properly.
CSCsf When the flash memory of a stack member is almost full, it might take longer to start up than other member switches. This might cause that switch to miss the stack-master election window. As a result, the switch might fail to become the stack master even though it has the highest priority.
CSCsg In a mixed stack of Catalyst switches and Catalyst X or E switches, when the stack reloads, the Catalyst X or Catalyst E might not become stack master, even it has a higher switch priority set. CSCsi A stack member switch might fail to bundle Layer 2 protocol tunnel ports into a port channel when you have followed these steps: 1. Switch config-if l2protocol-tunnel cdp.
Switch config-if channel-group 1 mode on CSCsk Stack Power Catalyst X only When a power stack has been configured in redundant mode, which is not the default, and then split by either removing cables or disabling StackPower ports, the newly created power stack has the same mode as the former power stack, but this is not shown in the configuration file.
This problem happens intermittently with certain stacking configurations and only occurs on the member switches. You can use one of these workarounds: — Enter the shutdown and the no shutdown interface configuration commands to reset the port. CSCsi When you enter the boot host retry timeout global configuration command to specify the amount of time that the client should keep trying to download the configuration and you do not enter a timeout value, the default value is zero, which should mean that the client keeps trying indefinitely.
However, the client does not keep trying to download the configuration. If a port is configured in Multi-Auth mode, all hosts connecting on that port must be assigned the same SGT. When a host tries to authenticate, its assigned SGT must be the same as the SGT assigned to a previously authernticated host. Port-to-SGT mapping cannot be configured on host-to-switch links. Device Manager Limitations When you are prompted to accept the security certificate and you click No , you only see a blank screen, and the device manager does not launch.
Hardware Limitations. The Catalyst X and Catalyst E switches do not support switch stacking. However, the show processes privileged EXEC command still lists stack-related processes. This occurs because these switches share common code with other switches that do support stacking.
Catalyst E switches, Catalyst switches, and Cisco EtherSwitch service modules can be in the same switch stack. In this switch stack, we recommend that the Catalyst E switch be the stack master. Control Plane Protection Catalyst X, E, X and E switches internally support up to 16 different control plane queues. Cisco IOS Notes Unlike other platforms, the response to an Energywise query on a Catalyst X or X is the actual switch power consumption and not a fixed number.
AutoQoS Error: ciscophone input service policy was not properly applied. Device Manager Notes You cannot create and manage switch clusters through the device manager. When the switch is running a localized version of the device manager, the switch displays settings and status only in English letters.
Input entries on the switch can only be in English letters. For device manager session on Internet Explorer, popup messages in Japanese or in simplified Chinese can appear as garbled text. These messages appear properly if your operating system is in Japanese or Chinese.
We recommend this browser setting to speed up the time needed to display the device manager from Microsoft Internet Explorer. From Microsoft Internet Explorer: 1. Click OK. The HTTP server interface must be enabled to display the device manager.
By default, the HTTP server is enabled on the switch. If you are not using the default method of authentication the enable password , you need to configure the HTTP server interface with the method of authentication used on the switch Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface: Command. To view the details of a caveat listed in this document: 1. Open Caveats Unless otherwise noted, these caveats apply to Catalyst X, E, X, and E switches CSCug Catalyst X, X, and E switches When Catalyst 3k switch stack is not configured as rep edge and is just part of the ring, it causes convergence of about 4 to 8 seconds for some streams.
CSCte In a Smart Install network, when the director is connected between the client and the DHCP server and the server has options configured for image and configuration, then the client does not receive the image and configuration files sent by the DHCP server during an automatic upgrade. Use one of these workarounds: — If client needs to upgrade using an image and configuration file configured in the DHCP server options, you should remove the client from the Smart Install network during the upgrade.
CSCtj Mediatrace does not report statistics on the initiator under these conditions: — The responder is a mixed switch stack with a Catalyst as the master switch — The ingress interface on the responder from the initiator is on a member switch. CSCtn Catalyst X and X switches When you enter the copy running-config startup config privileged EXEC command on the switch, the running configuration is not always saved to the startup configuration on the first attempt.
Although the non-seed switch is authenticated and authorized to connect to the network, supplicant devices connected to the non-seed switch might be unable to connect to the network, under these circumstances: — CTS caching is enabled on the seed switch and not enabled on the non-seed switch. CSCtr ASP now uses a device classifier, which determines the type of device that is connected to the switch.
CSCua The following message may be erroneously displayed during the boot up process. Caveat ID Number. Bug ID. The configuration is as show below: kron occurrence Daily-writeNet at recurring policy-list writeNet! CSCts When rsh command constructs are used within Tclscript, Tcl fails to send the router hostname which causes the rsh command constructs to fail authorization to a remote router.
CSCum In a Catalyst X switch stack, the switches experience a slow performance with the following message. Expected during linecard OIR The issue is observed in switches running CSCun After system reload, ip ssh source-interface shows in startup-config but disappears from running-config. Save the configuration and reload 5. CSCuo When port-security is configured on all ports and when the end host is moved, the mac address table is out of sync.
The workaround is to clear the mac address table. The workaround is to disable one of the following: — Port-security — Voice Vlan on the interface remove voice vlan config from the interface CSCup Catalyst Switches E and X Due to a timing issue, the port channel member port on the slave switch of the stack loops during boot up.
The workaround is to remove the VTP password. CSCuq 10G link convergence is better than 1G convergence during link pull or link down. CSCts A switch configured with login quiet-mode resets when you enter the login block-for or no login block-for commands.
CSCua When you configure Flex Link on stacks containing interfaces from different switches, the interfaces start flapping continuously. CSCuc Port-channel interface flaps while adding or removing a VLAN from the trunk on a port-channel interface if one or more port members are not in P or D states. CSCue Catalyst Switches X and X In a stack of Catalyst x switches, port security enabled ports block all the network traffic through them. The workaround is to perform any one of the following steps: — Remove the clustering configuration from the switch.
There is no workaround needed. CSCuf Catalyst Switch E Netflow cache is not created after applying a flow monitor to the interface on the member switch. CSCui Web authentication does not work. The workaround is to disable EnergyWise. The workaround is to implement SNMP view using the following commands: snmp-server view cutdown iso included snmp-server view cutdown at excluded snmp-server view cutdown ip.
The workaround is to apply protocol filters to the device sensor output by entering the following global configuration commands: no macro auto monitor device-sensor filter-spec dhcp exclude all device-sensor filter-spec lldp exclude all device-sensor filter-spec cdp exclude all If the memory leak continues in the "DHCPD Receive" process, disable the built-in DHCP server by entering the no service dhcp global configuration command.
CSCuc Catalyst X and X switches On running show interface command, incorrect value is displayed in input error counter. CSCud If a policy map attached to the switch interface is modified then the corresponding QoS policy works incorrectly. CSCue On the Catalyst S switch stack, when the login block command is configured and the running config is saved using the wr command on the master, it makes the master down.
CSCue When the secret password is configured, the password is not saved. CSCue Catalyst X switches A vulnerability in the Service Module could allow an authenticated, local attacker to gain root access to the kernel running on the Service Module. The work around is to perform any of the following action: — Enter the macsec command on the active interface always and not on the inactive interface.
CSCuf Catalyst X switch When reloading a switch in a stack that contains a service module inside a member switch, the links on the service module does not show up after reloading the member switch. CSCty The down-when-looped interface configuration command is not supported with default speed or with BaseT advertisements on the gigabit medium independent interface GMII interface.
There is no known workaround. The workaround is to use the following procedure when you apply an ACL to line vty 0 4 and line vty 5 1. See the following example: ip access-list standard vty-acl.
