How to rename router interfaces names

[CARLO CIANFARANI]

Hi,

to simplify a Lab layout, I would like to rename some router interfaces (e.g. rename FastEthernet1/0 in FastEthernet0/0)

Do you think is possible in some way ?

Thanks Carlo

Carlo,

These are hardset by the slot/interface number that the device is using. Unfortunately, you won't be able to rename them like this. You could put a description on each though:

int fa1/0

desc To Internet Provider

int fa0/0

desc Internal Lan

When you want to see your descriptions, you can run:

sh int description

HTH,

John

Hi, I know this was asked a few years back but here is a suggestion. Let's say GigabitEthernet 0/0 of R5 is connected to GigabitEthernet 0/1 of R6, you could create a subinterface G0/0.56 on R5 and a subinterface G0/0.56 on R6 and use these to connect your two routers. You would have to enable the dot1q encapsulation to make this work.
