Backup and restore configuration file on Catalyst 2950 and router 1721

PrerequisitesRequirementsBefore you use the information in this document, make sure that you meet these requirements:

Access to a Trivial File Transfer Protocol (TFTP) or File Transfer Protocol (FTP) server. Connectivity - Routers must be able to access the FTP or TFTP server. Use

the ping command to verify connectivity.

Use a TFTP Server to Backup and Restore a ConfigurationThis is a step-by-step approach to copy a configuration from a router to a TFTP server, and back to another router. Before you proceed with this method, make sure you have a TFTP server on the network to which you have IP connectivity.

1. At the Router> prompt, issue the enable command, and provide the required password when prompted.

The prompt changes to Router#, which indicates that the router is now in privileged mode.

2. Copy the running configuration file to the TFTP server:

CE_2#copy running-config tftp:Address or name of remote host []? 64.104.207.171Destination filename [ce_2-confg]? backup_cfg_for_my_router!!1030 bytes copied in 2.489 secs (395 bytes/sec)CE_2#

3. Open the configuration file with a text editor. Search for and remove any line that starts with "AAA".

Note: This step is to remove any security commands that can lock you out of the router.

4. Copy the configuration file from the TFTP server to a new router in privileged (enable) mode which has a basic configuration.

Router#copy tftp: running-configAddress or name of remote host []? 64.104.207.171Source filename []? backup_cfg_for_my_routerDestination filename [running-config]?Accessing tftp://10.66.64.10/backup_cfg_for_my_router...Loading backup_cfg_for_router from 64.104.207.171 (via FastEthernet0/0): ![OK - 1030 bytes]

1030 bytes copied in 9.612 secs (107 bytes/sec)CE_2#

Use TFTP to Save and Restore Cisco IOS Configuration. 1- Start TFTP server.

2- Configure the TFTP server. To configure TFTP server, select menu option File | configure. Verify the following settings:

3- Save Router1 configuration to TFTP server. From HyperTerminal, begin a TFTP upload to the TFTP server: Router1#copy running-config tftp: Address or name of remote host []? (Host IP) Destination filename [router1-confg]? <ENTER> !! 1081 bytes copied in 2.008 secs (538 bytes/sec) Router1# Verify a successful upload transfer. Open Log file c:\Program Files\SolarWinds\Free Tools\TFTP-Server.txt. Contents should be similar to the following: 3/25/2007 12:29 :Receiving router1-confg from (10.250.250.254) 3/25/2007 12:29 :Received router1-confg from (10.250.250.254), 1081 bytes Verify the transferred file. Use Microsoft Word or Wordpad to examine the contents of file c:\TFTP-Root\router1-confg.

Part 2.7: Restore Router1 configuration from TFTP server. Download Router1 configuration file from the TFTP server: Router# copy tftp startup-config Address or name of remote host []? 10.250.250.253 Source filename []? router1-confg Destination filename [startup-config]? <ENTER> Accessing tftp://10.250.250.249/router1-confg...

The configuration should be the same as what was configured Similar to uploading a configuration file, the IOS can also be stored off-line for future use. To discover the IOS filename, issue the Cisco IOS command show version.
