Re: remove subinterface

Hi Frined,

If you want to completely remove the subinterface from your configuration you can simply go to global config mode and give a command

"no interface "

eg:

no interface fa0/0.0

no interface fa0/0.1

If you just want to shut your intervlan routing from that subinterface you can go to that subinterface and give "shut"

Re: remove subinterface

Hello,

the command ´no interface FastEthernet0/0.1´ will disable the interface, in order to get rid of it in the actual configuration, you have to reboot the router...

Hello,

unfortunately, to my best knowledge, that is the only way to remove the subinterface - reboot...

Hitry first deleting the ip

Hi

try first deleting the ip  address and then the sub interface: I found this worked for a serial connection so I guess it will be the same for an ethernet interface.

Cheers

It may be good form to remove

It may be good form to remove the IP address before you delete the subinterface, but it is not required.

 

If you do no interface fastethernet0/0.1 then the subinterface will be only partly gone. Especially in things like the output of show ip interface brief the subinterface will still show up until you reboot the router.
