This section describes administrative tasks that need to be performed on a Catalyst 6000 or 6500 series switch:
Configuration files contain the switch configuration information. Often, you will want to view the current configuration, back up the existing configuration before making changes, or configure the switch using a backup configuration.
To view the current configuration file, perform this task in privileged mode:
| Task | Command |
|---|---|
Display the configuration file onscreen. | show configuration |
This example shows how to display the current configuration:
Console> (enable) show config ..... .......... .......... ......... ......... ........... .. begin set password $1$FMFQ$HfZR5DUszVHIRhrz4h6V70 set enablepass $1$FMFQ$HfZR5DUszVHIRhrz4h6V70 set prompt Console> set length 24 default set logout 20 set banner motd ^C Catalyst 6000 #2 Software Release 5.1 (1) IP address 172.20.52.70 ^C ! #system set system baud 9600 set system modem disable set system name set system location set system contact <... output truncated ...> ! #switch port analyzer set span disable ! #cam set cam agingtime 1,100,522-524,1003,1005 300 end Console> (enable)
To change the system software image on a Catalyst 6000 or 6500 series switch, obtain the software image file, place it on a Trivial File Transfer Protocol (TFTP) server, and copy the image to the switch using the copy command. You must reset the switch to run the new software, which will disconnect any Telnet sessions established with the switch (a console port session will remain connected).
| Task | Command |
|---|---|
Step 1 Copy a software image from a TFTP server to a Flash device (you are prompted for the Flash device name). | copy tftp file-id |
Step 2 Prepend the image filename to the BOOT environment variable, so the new image boots when you reset the switch. | set boot system flash device:filename prepend |
Step 3 Reset the switch. | reset |
Step 4 Check the version number of the installed software image. | show flash |
This example shows how to copy a software image from a TFTP server, reset the switch, and check the version of the installed software image:
Console> (enable) copy tftp flash IP address or name of remote host []? 172.20.52.3 Name of file to copy from []? cat6000-sup.5-1-2.bin Flash device [bootflash]? Name of file to copy to [cat6000-sup.5-1-2.bin]? 4369664 bytes available on device bootflash, proceed (y/n) [n]? y CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCCC File has been copied successfully. Console> (enable) set boot system flash bootflash:cat6000-sup.5-2-1.bin prepend BOOT variable = bootflash:cat6000-sup.5-2-1.bin,1;bootflash:cat6000-sup.5-1-1.bin ,1; Console> (enable) reset system This command will reset the system. Do you want to continue (y/n) [n]? y Console> (enable) <... output truncated ...> Autoboot executing command: "boot bootflash:cat6000-sup.5-2-1.bin" <... output truncated ...> Cisco Systems Console Enter password: Console> show flash File Version Sector Size Built --------------- -------------------- ------------ ------- ----------------- c6000 nmp 5.2(1) 02-11 1882546 01/15/99 14:06:03 <... output truncated ...> Console>
You can use the Flash file system to store multiple system-software images and configuration files locally on the switch (instead of having to save them to a TFTP server).
Flash PC (PCMCIA) cards must be formatted before use. To format a Flash PC card, or any Flash device, perform this task in privileged mode:
| Task | Command |
|---|---|
Format the desired Flash device. | format [m/]device: |
This example shows how to format a Flash PC card:
Console> (enable) format slot0: All sectors will be erased, proceed (y/n) [n]? y Enter volume id (up to 30 characters): Supervisor Flash Card Formatting sector 1 Format device slot0 completed Console> (enable)
To change the default Flash device and see which device is the current default, perform this task:
| Task | Command |
|---|---|
Step 1 Set the default Flash device for the switch. | cd device: |
Step 2 Verify the default Flash device for the switch. |
This example shows how to change the default Flash device and how to verify which device is the default:
Console> (enable) cd slot0: Console> (enable) pwd slot0 Console> (enable) cd bootflash: Console> (enable) pwd bootflash Console> (enable)
To copy Flash files between Flash devices or between a Flash device and a TFTP server, perform these tasks in privileged mode:
| Task | Command |
|---|---|
| copy config {flash | file-id | tftp} |
| copy file-id device:[file-id] |
| copy file-id tftp |
| copy tftp file-id |
This example shows how to copy the current configuration to the current default Flash device:
Console> (enable) copy config flash Flash device [slot0]? Name of file to copy to []? 6000_config.cfg Upload configuration to slot0:6000_config.cfg 13259828 bytes available on device slot0, proceed (y/n) [n]? y ..... .......... .......... .. Configuration has been copied successfully. Console> (enable)
This example shows how to copy a file from the current default Flash device to a different Flash device:
Console> (enable) copy 6000_config.cfg slot0: 16383872 bytes available on device slot0, proceed (y/n) [n]? y File has been copied successfully. Console> (enable)
This example shows how to copy a file from the current default Flash device to a TFTP server:
Console> (enable) copy 6000_config.cfg tftp IP address or name of remote host []? 10.1.1.3 Name of file to copy to [6000_config.cfg]? - File has been copied successfully. Console> (enable)
This example shows how to copy a file from a TFTP server to a Flash device:
Console> (enable) copy tftp flash IP address or name of remote host []? 10.1.1.3 Name of file to copy from []? 6000_config.cfg Flash device [bootflash]? slot0: Name of file to copy to [6000_config.cfg]? 16376740 bytes available on device slot0, proceed (y/n) [n]? y - File has been copied successfully. Console> (enable)
To display a list of files on a Flash device, perform this task in privileged mode:
| Task | Command |
|---|---|
Display a list of files on a Flash device. | dir [[device:]file-id] [all | deleted | long] |
This example shows how to list the files on a Flash device:
Console> (enable) dir -#- -length- -----date/time------ name 2 7004 Apr 19 1998 10:06:37 6000_config.cfg 3 3102520 Apr 19 1998 10:09:42 cat6000-sup.5-1-1.bin 13259956 bytes available (3124044 bytes used) Console> (enable)
To delete files on a Flash device, perform this task in privileged mode:
| Task | Command |
|---|---|
Delete a file on a Flash device. | delete [[m/]device:]file-id |
This example shows how to delete a file on a Flash device:
Console> (enable) delete 6000_config.cfg Console> (enable)
To undelete a file on a Flash device, perform these steps in privileged mode:
| Task | Command |
|---|---|
Step 1 List the deleted files on the current default Flash device. | |
Step 2 Undelete the desired file. Use the file index number shown in the first column (#) of the dir display to identify the file. | undelete index |
This example shows how to undelete a file on a Flash device:
Console> (enable) dir deleted -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name 2 .D ffffffff 6d005dfe 317754 15 7964 Aug 18 1998 10:27:38 6000_config. cfg 13273260 bytes available (3110740 bytes used) Console> (enable) undelete 2 Console> (enable)
To free space on a Flash device, use the squeeze command to permanently remove deleted files. You cannot use the undelete command to restore files you deleted prior to entering the squeeze command. To squeeze a Flash device, perform this task in privileged mode:
| Task | Command |
|---|---|
Permanently remove deleted files from a Flash device. | squeeze [m/]device: |
This example shows how to permanently remove deleted files from a Flash device:
Console> (enable) squeeze slot0: All deleted files will be removed, proceed (y/n) [n]? y Squeeze operation may take a while, proceed (y/n) [n]? y Erasing squeeze log Console> (enable)
Sometimes you need to reset an individual module or the entire switch (for example, when you install a new system software image). If you are connected to the switch via Telnet, resetting an individual module can disconnect your session (if the Telnet session was established through a port on that module). If you reset the entire switch, your Telnet session will disconnect.
To reset an individual module installed in the switch, perform this task in privileged mode:
| Task | Command |
|---|---|
Reset an individual module. | reset mod_num |
This example shows how to reset an individual module in the switch:
Console> (enable) reset 2 This command will reset module 2 and may disconnect your telnet session. Do you want to continue (y/n) [n]? y Resetting module 2... Console> (enable) 08/18/1998,09:32:23:SYS-5:Module 2 is online Console> (enable)
To reset the entire switch, perform this task in privileged mode:
| Task | Command |
|---|---|
Reset the switch. | reset |
This example shows how to reset the entire switch:
Console> (enable) reset This command will reset the system. Do you want to continue (y/n) [n]? y Console> (enable) <... output truncated ...>
