Recently been using Cisco Network Assistant 5.4 to back up the configuration of my Catalyst 3500XL switches. However, yesterday for the first time I tried using the Maintenance/Configuration Archive Restore function to load the configuratin on a factory default switch. The restore went well, and I can see my settings in running-config. But as soon as the config loaded and the switch reset was done, all of the FastEthernet ports were not working. Resetting the switch to factory default does restore the ports. Tried this Resore on a second switch and the same thing happened. The port status show as "FastEthernet0/1 is down, link protocol is down". This port is enabled in the configuration. I can't see any reason for the ports to drop out after reloading the configuration..... can anyone point me in the right direction?
