This 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 []? 64.104.207.171
Destination 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-config
Address or name of remote host []? 64.104.207.171
Source filename []? backup_cfg_for_my_router
Destination filename [running-config]?
Accessing tftp://10.66.64.10/backup_cfg_for_my_router...
