How can I rename my Cisco 1812 Router's port name from "FastEthernet 0" to "FastEthernet 0/0"

If I type

Router1#sh ip int briefCmd_ShIPintBrief.JPG

it shows the interface name like

FastEthernet 0

FastEthernet 1

and so on...

and when I enter global configuration mode and type

#int FastEthernet 0/0, or Fa0/0

it shows error like below

Router1(config)#interface fastEthernet 0/0
                                                             ^
% Invalid input detected at '^' marker.

it does not accept "/" in the name in the FastEthernet port

But, if I write like below

#int FastEthernet 0   then its ok.

 

So, my concern is how I can rename my router's FastEthernet port's interface name from fastEthernet 0 to fastEthernet 0/0 and fastEthernet 1 to fastEthernet 0/1

Hi there,

You cannot rename the interface names.

Since the 1812 is a fixed port router, it has no concept of 'slots' (additional interface cards, ie WICS) so it has no need to use the naming convention x/x , ie <slot>/<interface>

 

cheers,

Seb.
