If you configure the enable secret command, it takes precedence over the enable password command; the two commands cannot be in effect simultaneously. To configure the switch to require an enable password, perform either one of these tasks:. Specifies a secret password that will be saved using a nonreversible encryption method. If enable password and enable secret commands are both set, users must enter the enable secret password.
When you enter either of these password commands with the level option, you define a password for a specific privilege level. After you specify the level and set a password, give the password only to users who need to have access at this level. Use the privilege level configuration command to specify commands accessible at various levels. If you enable the service password-encryption command, the password you enter is encrypted.
When you display the password with the more system:running-config command, the password displays the password in encrypted form. If you specify an encryption type, you must provide an encrypted password—an encrypted password you copy from another Catalyst series switch configuration.
Note You cannot recover a lost encrypted password. See the "Recovering a Lost Enable Password" section for more information. For information on how to display the password or access level configuration, see the "Displaying the Password, Access Level, and Privilege Level Configuration" section. Each service can be locked into its own database to take advantage of other services available on that server or on the network, depending on the capabilities of the daemon.
Your switch can be a network access server along with other Cisco routers and access servers. A network access server provides connections to a single user, to a network or subnetwork, and to interconnected networks as shown in Figure The authentication facility can conduct a dialog with the user such as, after a username and password are provided, to challenge a user with several questions such as home address, mother's maiden name, service type, and social security number. For example, a message could notify users that their passwords must be changed because of the company's password aging policy.
Network managers can use the accounting facility to track user activity for a security audit or to provide information for user billing. Accounting records include user identities, start and stop times, executed commands such as PPP , number of packets, and number of bytes. The daemon prompts for a username and password combination, but can include other items such as the user's mother's maiden name.
If the switch is configured to require authorization, authorization begins at this time. If an ERROR response is received, the switch typically tries to use an alternative method for authenticating the user. After authentication, the user undergoes an additional authorization phase if authorization has been enabled on the switch.
A method list defines the sequence and methods used to authenticate, to authorize, or to keep accounts on a user. You can use method lists to designate one or more security protocols, ensuring a backup system if the initial method fails. The software uses the first method listed to authenticate, to authorize, or to keep accounts on users; if that method does not respond, the software selects the next method in the list.
This process continues until there is successful communication with a listed method or the method list is exhausted. You can configure the switch to use a single server or AAA server groups in order to group existing server hosts for authentication. You can group servers to select a subset of the configured server hosts and use them for a particular service. The server group is used with a global server-host list and contains the list of IP addresses of the selected server hosts.
Enter this command multiple times to create a list of preferred hosts. The software searches for hosts in the order in which you specify them. The default is port The range is 1 to The default is 5 seconds. The range is 1 to seconds. To configure AAA authentication, define a named list of authentication methods and then apply that list to various ports. The method list defines the types of authentication you intend to perform and the sequence in which you intend to perform them; you must apply the list to a specific port before you can perform any of the defined authentication methods.
The only exception is the default method list which, by coincidence, is named default. The default method list is automatically applied to all ports except those that have a named method list explicitly defined. A defined method list overrides the default method list.
A method list describes the sequence and authentication methods that must be queried to authenticate a user. You can designate one or more security protocols for authentication, ensuring a backup system for authentication in case the initial method fails.
The software uses the first method listed to authenticate users; if that method fails to respond, the software selects the next authentication method in the method list. This process continues until there is successful communication with a listed authentication method or until all defined methods are exhausted. If authentication fails at any point in this cycle—meaning that the security server or local username database responds by denying the user access—the authentication process stops, and no other authentication methods are attempted.
Beginning in privileged EXEC mode, follow these steps to configure login authentication:. The default method list is automatically applied to all ports. The additional methods of authentication are used only if the previous method returns an error, not if it fails.
Before you can use this authentication method, you must define an enable password by using the enable password global configuration command. Before you can use this authentication method, you must define a line password. Use the password password line configuration command. You must enter username information in the database. Use the username password global configuration command. You must enter username information in the database by using the username name password global configuration command.
Enter line configuration mode, and configure the lines to which you want to apply the authentication list. To disable AAA, use the no aaa new-model global configuration command. AAA authorization limits the services available to a user. When AAA authorization is enabled, the switch uses information retrieved from the user's profile, which is located either in the local user database or on the security server, to configure the user's session.
The user is granted access to a requested service only if the information in the user profile allows it. Note Authorization is bypassed for authenticated users who log in through the CLI even if authorization has been configured. The exec keyword might return user profile information such as autocommand information.
The AAA accounting feature tracks the services that users are accessing and the amount of network resources that they are consuming. Each accounting record contains accounting attribute-value AV pairs and is stored on the security server. This data can then be analyzed for network management, client billing, or auditing. Because protocol analyzers can examine packets and read passwords , you can increase access security by configuring the Cisco IOS software to encrypt passwords.
Encryption prevents the password from being readable in the configuration file. Encryption occurs when the current configuration is written or when a password is configured. Password encryption is applied to all passwords, including authentication key passwords, the privileged command password, console and virtual terminal line access passwords, and Border Gateway Protocol BGP neighbor passwords.
The service password-encryption command keeps unauthorized individuals from viewing your password in your configuration file. Although you cannot recover a lost encrypted password that is, you cannot get the original password back , you can regain control of the switch after having lost or forgotten the encrypted password. You can configure up to 16 hierarchical levels of commands for each mode. By configuring multiple passwords, you can allow different sets of users to have access to specified commands.
For example, if you want many users to have access to the clear line command, you can assign it level 2 security and distribute the level 2 password fairly widely. If you want more restricted access to the configure command, you can assign it level 3 security and distribute that password to fewer users. The procedures in the following sections describe how to configure additional levels of security:.
Switch config privilege mode level level command. To change the default privilege level for a given line or a group of lines, perform this task:. Switch config-line privilege level level. This example shows how to display the password and access level configuration:. Step 1 Connect to the console interface. Step 4 Reboot the system. Step 5 Access enable mode this can be done without a password if a password has not been configured.
Step 6 View or change the password, or erase the configuration. Step 8 Reboot the system. These sections describe how the startup configuration on the supervisor engine works and how to modify the BOOT variable and the configuration register:. The supervisor engine boot process involves two software images: ROM monitor and supervisor engine software.
Two user-configurable parameters determine how the switch boots: the configuration register and the BOOT environment variable. The configuration register is described in the "Modifying the Boot Field and Using the boot Command" section. From ROMMON mode, you can manually load a software image from bootflash or a Flash disk, or you can boot up from the management interface. This variable is described in the "Switch " section. If you are connected through a terminal server, you can escape to the Telnet prompt and enter the send break command to enter ROMMON mode.
Note Ctrl-C is always enabled for five seconds after you reboot the switch, regardless of whether the configuration-register setting has Ctrl-C disabled. The switch uses a bit software configuration register, which allows you to set specific system parameters. Here are some reasons why you might want to change the software configuration register settings:. Table lists the meaning of each of the software configuration memory bits. Table defines the boot field. Boot field see Table See Table Autoboots using image s specified by the BOOT environment variable.
If more than one image is specified, the switch attempts to boot the first image specified in the BOOT variable. As long as the switch can successfully boot from this image, the same image will be used on a reboot. If the switch fails to boot from the image specified in the BOOT variable, the switch will try to boot from the next image listed in the BOOT variable. If the end of the BOOT variable is reached without the switch booting successfully, the switch attempts the boot from the beginning of the BOOT variable.
The autoboot continues until the switch successfully boots from one of the images specified in the BOOT variable. The configuration register boot field determines whether the switch loads an operating system image and, if so, where it obtains this system image. The following sections describe how to use and set the configuration register boot field and the procedures you must perform to modify the configuration register boot field.
Bits 0 through 3 of the software configuration register contain the boot field. Note The factory default configuration register setting for systems and spares is 0x However, the recommended value is 0x When the boot field is set to either 00 or 01 or , the system ignores any boot instructions in the system configuration file and the following occurs:. You can enter the boot command only or enter the command and include additional boot instructions, such as the name of a file stored in Flash memory, or a file that you specify for booting from a network server.
If you use the boot command without specifying a file or any other boot instructions, the system boots from the default Flash image the first image in onboard Flash memory. Otherwise, you can instruct the system to boot up from a specific Flash image using the boot system flash filename command. You can also use the boot command to boot up images stored in the compact Flash cards located in slot 0 on the supervisor engine. Modify the boot field from the software configuration register.
To modify the software configuration register boot field, perform this task:. Modifies the existing configuration register setting to reflect the way you want the switch to load a system image. To modify the configuration register while the switch is running Cisco IOS software, follow these steps:.
Step 1 Enter the enable command and your password to enter privileged level, as follows:. Step 3 Configure the configuration register to 0x as follows:. Set the contents of the configuration register by specifying the value command variable, where value is a hexadecimal number preceded by 0x see Table Step 4 Enter the end command to exit configuration mode. The new value settings are saved to memory; however, the new settings do not take effect until the system is rebooted.
Step 5 Enter the show version EXEC command to display the configuration register value currently in effect; it will be used at the next reload. The value is displayed on the last line of the screen display, as shown in this sample output:. Step 6 Save your settings. Note that configuration register changes take effect only after the system reloads, such as when you enter a reload command from the console. Step 7 Reboot the system. The new configuration register value takes effect with the next system boot up.
Enter the show version EXEC command to verify the current configuration register setting. To verify the configuration register setting for the switch, perform this task:. In this example, the show version command indicates that the current configuration register is set so that the switch does not automatically load an operating system image.
You can enter multiple boot commands in the startup configuration file or in the BOOT environment variable to provide backup methods for loading a system image. Use the following sections to configure your switch to boot from Flash memory. Check the appropriate hardware installation and maintenance guide for information about types of Flash memory. To configure your switch to boot from Flash memory, perform the following procedure.
Refer to the appropriate hardware installation and maintenance publication for complete instructions on installing the hardware. Step 2 Configure the system to boot automatically from the desired file in Flash memory. You might need to change the configuration register value. See the "Modifying the Boot Field and Using the boot Command" section , for more information on modifying the configuration register. Step 3 Save your configurations.
Step 4 Power cycle and reboot your system to verify that all is working as expected. Although the ROM monitor controls environment variables, you can create, modify, or view them with certain commands. Note When you use the boot system and boot bootldr global configuration commands, you affect only the running configuration. To save the configuration for future use, you must save the environment variable settings to your startup configuration, which places the information under ROM monitor control.
Enter the copy system:running-config nvram:startup-config command to save the environment variables from your running configuration to your startup configuration. This command displays the settings for these variables as they exist in the startup configuration and in the running configuration if a running configuration setting differs from a startup configuration setting. If the Catalyst series switch is accessible to an tftp server, you can copy an image to the bootflash memory with the tftp command:.
When the copying completes, you can reboot the just-copied Catalyst series switch image to the image stored in the bootflash memory with the reload command:.

Updated: February 14, Chapter: Configuring the Switch for the First Time. Default Switch Configuration This section describes the default configurations for the Catalyst series switch.
Configuring the Relay Device You must configure a relay device to forward received broadcast packets to the destination host whenever a switch sends broadcast packets to which a host on a different LAN must respond.
For example, in Figure , configure the router interfaces as follows: On interface The prompt will change to the enable prompt : Switch Step 3 At the enable prompt , enter the configure terminal command to enter global configuration mode: Switch configure terminal Enter configuration commands, one per line. Verifying the Running Configuration Settings To verify the configuration settings you entered or the changes you made, enter the show running-config command at the enable prompt , as shown in this example: Switch show running-config Building configuration Current configuration:!
If you fail to do this step, your configuration will be lost the next time you reload the system. To configure a default gateway, perform this task: Command Purpose Step 1 Switch config ip default-gateway IP-address Configures a default gateway. Step 2 Switch show ip route Verifies that the default gateway is correctly displayed in the IP routing table. This example shows how to configure a default gateway and how to verify the configuration: Switch configure terminal Enter configuration commands, one per line.
For example, access servers display voice-related show command output. Additionally, the show protocol traffic commands are displayed for only the protocols enabled on your device. For a sample display of the output of the show tech-support command, see the individual show command listed. If you enter the show tech-support command without arguments, the output displays, but is not limited to, the equivalent of these show commands:.
Note Crypto information is not duplicated by the show dmvpn details command output. When the show tech-support command is entered on a virtual switch VS , the output displays the output of the show module command and the show power command for both the active and standby switches. Use of the optional cef , ipc , ipmulticast , isis , mpls , ospf , or rsvp keywords provides a way to display a number of show commands specific to a particular protocol or process in addition to the show commands listed previously.
For example, if your Technical Assistance Center TAC support representative suspects that you may have a problem in your Cisco Express Forwarding CEF configuration, you may be asked to provide the output of the show tech-support cef command. The show tech-support [ page ] [ password ] cef command will display the output from the following commands in addition to the output for the standard show tech-support command:. If you enter the ipmulticast keyword, the output displays, but is not limited to, these show commands:.
If you enter the wccp keyword, the output displays, but is not limited to, these show commands:. For a sample display of the output from the show tech-support command, refer to the documentation for the show commands listed in the "Usage Guidelines" section. Displays detailed information about neighboring devices discovered using Cisco Discovery Protocol. Displays the DECnet traffic statistics including datagrams sent, received, and forwarded.

The following is sample output from the show template command displaying template information. Use the show usb controllers command to display content such as controller register specific information, current asynchronous buffer addresses, and period scheduling information.
You can also use this command to verify that copy operations are occurring successfully onto a USB flash module. The following example is sample output from the show usb controllers command:. Optional Displays information only for the devices under the specified controller.
Optional Displays information only for the device with the specified address. The following example is sample output from the show usb device command:. If this field is reset to 0, each interface within a configuration specifies its own class information, and the various interfaces operate independently. If this field is set to a value between 1 and FEH, the device supports different class specifications on different interfaces, and the interfaces may not operate independently.
This value identifies the class definition used for the aggregate interfaces. If this field is set to FFH, the device class is vendor-specific. The subclass code supported by the device. The protocol supported by the device. If this field is set to 0, the device does not use class-specific protocols on a device basis.
If this field is set to 0xFF, the device uses a vendor-specific protocol on a device basis. The class code supported by the interface. If the value is set to 0xFF, the interface class is vendor specific. The subclass code supported by the interface. The protocol code supported by the interface. If this field is set to 0, the device does not use a class-specific protocol on this interface. If this field is set to 0xFF, the device uses a vendor-specific protocol for this interface.
To display information about registered USB class drivers and vendor-specific drivers, use the show usb driver command in privileged EXEC mode. The following example is sample output for the show usb driver command:. Table describes the significant field shown in the display. Indicates the fields that are used in enumeration comparison.
The driver can own different devices on the basis of their product or vendor IDs and device or interface class, subclass, and protocol codes. Optional Displays information only for a specified. If the port-number is not issued, information for all root ports will be displayed. The following sample from the show usb port command shows the status of the port 1 on the router:. To display information about the port state and all attached devices, use the show usb tree command in privileged EXEC mode.
The following example is sample output from the show usb tree command. Optional One of the ten available flash drives you can choose from; valid values: If you do not specify a number, 0 is used by default. Use the show usbtoken command to verify whether a USB eToken is inserted in the router. The following example is sample output from the show usbtoken command:. To display information about the currently loaded software along with hardware and device information, use the show version command in user EXEC, privileged EXEC, or diagnostic mode.
Options include:. This command was modified to include information about the clock card on CMTS routers. Support for this command on the Supervisor Engine 2 was extended to This command displays information about the Cisco IOS software version currently running on a routing device, the ROM Monitor and Bootflash software versions, and information about the hardware configuration, including the amount of system memory. Because this command displays both software and hardware information, the output of this command is the same as the output of the show hardware command.
The show hardware command is a command alias for the show version command. Specifically, the show version command provides the following information:. Entering show version without any of the options on the Cisco ASR Series Router will generate output similar to show version on other Cisco routers.
In order to understand the show version output on Cisco ASR Series Routers, it is important to understand that the individual sub-packages run the processes on the router. Among other things, the output of this command provides information on where various individual sub-packages are stored on the router, and which processes these individual sub-packages are and are not currently running.
More specifically, the show version installed command displays each individual sub-package file on the router, the hardware where the sub-package could be running, and whether the sub-package is currently being run on that hardware. The output includes the individual sub-package file, the hardware where the sub-package could be running, and whether the sub-package is currently being run on that hardware.
The show version running command displays only the individual sub-packages that are currently active. The output includes the individual sub-package file and the hardware where the sub-package is running. The following is sample output from the show version command issued on a Cisco router running Cisco IOS Release This output shows the total bandwidth capacity and the bandwith capacity that is configured on the Cisco For example, Note In the full software image filename, Registered Cisco.

In the shared memory scheme Cisco , , , and Series , a percentage of DRAM is used for packet buffering by the router's network interfaces. The second value, K, is the Packet memory. Shows the current configured hex value of the software configuration register.
If the value has been changed with the config-register command, the register value that will be used at the next reload is displayed in parenthesis. The boot field final digit of the software configuration register dictates what the system will do after a reset. The factory-default setting for the configuration register is 0x This value indicates that the router will attempt to load a Cisco IOS software image from Flash memory and load the startup configuration file.
This example shows how to display the configuration of the system hardware, the software version, the names and sources of configuration files, and the boot images:. Table describes the fields that are shown in the example. Version number. Always specify the complete version number when reporting a possible software problem. In the example output, the version number is Log of how the system was last booted, both as a result of normal system startup and of system error.
For example, information can be displayed to indicate a bus error that is typically the result of an attempt to access a nonexistent address, as follows:. If the software was booted over the network, the Internet address of the boot host is shown. If the software was loaded from onboard ROM, this line reads "running default software. Remaining output in each display that shows the hardware configuration and any nonstandard software options.
The output of the show version EXEC command can provide certain messages, such as bus error messages. If such error messages appear, report the complete text of this message to your technical support specialist. The following is sample output from the show version command for a Cisco uBR VXR with the cable clock card installed:. Table describes significant fields shown in these displays. Also displayed is a log of how the system was last booted, as a result of normal system startup or system error.
The remaining output in each display shows the hardware configuration and any nonstandard software options. The output of the show version command can also provide certain messages, such as bus error messages. In the following example, the show version installed command is entered on a Cisco ASR Series Router in diagnostic mode.
In the following example, the show version provisioned command is entered to gather information on which sub-packages are provisioning which components on the router. In the following example, the show version running command is entered to view which sub-packages are active on which hardware elements on the router. Table show version installed, provisioned, and running Field Descriptions. Reveals if the sub-package is active or inactive for the specific hardware component only.

Copy the new software image into the bootflash from TFTP server and verify if the image is properly copied. Check if the file size of the new image matches exactly the size mentioned on the software center on Cisco. If there is a difference, check whether the image was corrupt during transfer. Right click on the filename and choose Properties in order to verify the actual file size in bytes. Verify whether you have enough space available in disk0: to copy the new image from TFTP server into disk0.
You can check the size of the new image on the PC that hosts the file. Delete the current image in disk0: with the delete disk0:catsupk8. Then issue the squeeze disk0: command in order to erase all deleted files from the device. This step is optional.
Copy the new software image into disk0 from the TFTP server and verify whether the image is properly copied. If there is a difference, check whether the image became corrupt during transfer. Note: This procedure uses an FTP server, and there were no problems during the image transfer.
Verify that you have enough space available in disk0: in order to copy the new image from the TFTP server into disk0. Delete the current image in disk0: with the delete disk0:catsup32pfc3k8. Note: The squeeze command does not work with the Supervisor If there is a difference, check whether the image got corrupt during transfer. This example uses the IP address A bootloader image is not a requirement for the MSFC2.
However, Cisco recommends that you use a boot image as described in this procedure. A boot image is a much smaller, scaled-down version of the system image. With a boot image, you can perform a TFTP image transfer if the main system image becomes corrupt or lost.
The best practice is to keep the main software image in slot0 and the boot loader image in the MSFC bootflash. You can check the size of the new image on the PC to which it is downloaded. The Supervisor Engine , uses the term disk0: and disk1: rather than slot0: , so in this example, replace the word slot0: with disk0: or disk1: , which depends upon which disk you use. Copy the new main software image into slot0, and the boot image into bootflash from the TFTP server. Verify whether the images are copied correctly.
Check that the file size of the new image matches the size on the software center. If they do not match, check whether the image got corrupt during transfer. Change the boot variables so that the switch boots with the new software and boot image after reload. You can verify the boot variables with the show running-config or show bootvar commands. Note: Because some of the latest software images for the Supervisor Engine are larger than the bootflash device, a CompactFlash card is recommended.
You can check the size of the new image to which it is downloaded. The Supervisor Engine uses the term disk0: or disk1: rather than slot Note: Issue this command in order to check the support of squeeze command:. Verify that the images are copied correctly.
If they do not match, it is possible that the image got corrupted during transfer. Change the boot variables so that the switch boots with the new software image after reload. Issue the show running-config or show bootvar commands in order to verify the boot variables. The Supervisor Engine 32 uses the term disk0: rather than slot Issue the show running-config or show bootvar commands in order to check the boot variables.
Redundant Supervisor Engines must be of the same type with the same model feature card in order to support redundancy. When you install two Supervisor Engines, the first one to come online becomes the active module. The second Supervisor Engine goes into standby mode. On the standby Supervisor Engine, the console port is inactive. Redundant Supervisor Engines are not swappable.
The system continues to operate with the same configuration after it switches over to the redundant Supervisor Engine. The error occurs in CatOS switches while they try to copy an image to bootflash or squeeze the bootflash that has an incompatible format. This error occurs even if the bootflash is empty:. The software upgrade can fail due to reasons such as IP connectivity problems between the switch and TFTP server, incorrectly set boot variables, or the power failure during the copy operation of the software image to the switch.
Refer to these documents for software recovery procedures:. A software downgrade on switches that run CatOS always causes loss of configuration. Issue the copy config tftp command in order to back up your configuration to a TFTP server. Alternatively, issue the copy config flash command in order to back up the configuration to a Flash device.
