Hello,

the default interface status is 'no shut'. When you issue a 'default interface te0/0/0' the interface loses all previous configuration and is set to its default, which is 'no shut'.

Is that what you are referring to ?

Yes, I also think so. 

After the default command, show run interface te0/0/0 can get the output:

"% No such configuration item(s)", we cannot see any info on the interface. but it does exist, right?

Thanks

Hello,

exactly. When you do a 'show int brief' the interface should show up. Since you reset it to its default values, there is no running config.
