Hi everyone,

First one was configured in nvram at startup.

Second one has been configure manually with in a config session.

Really what the router says :)

Are you familiar with the concept of "startup configuration" and "config term" in IOS ?

As Paolo stated, when you see an interface listed with Manual it means the IP address was configured on that interface after the router was rebooted.

For instance:

Router(config)#int s0/0

Router(config-if)#ip add 192.168.1.1 255.255.255.0

Router(config-if)#no shut

Router(config-if)#end

Router#sh ip int bri

*May 10 11:42:49.843: %SYS-5-CONFIG_I: Configured from console by console

Interface IP-Address OK? Method Status Protocol

Serial0/0 192.168.1.1 YES manual up up

Now, if I reboot the router, the interface chances to NVRAM.

Router#sh ip int bri

Interface IP-Address OK? Method Status Protocol

Serial0/0 192.168.1.1 YES NVRAM up up

HTH,
