Introduction to the Cisco IOS and SDM

But the rest of the modules are different—they use three numbers instead of two. The first 0

is the router itself, and then you choose the slot, and then the port. Here’s an example of a serial

interface on my 2811:

Todd(config)#interface serial ?

<0-2> Serial interface number

Todd(config)#interface serial 0/0/?

<0-1> Serial interface number

Todd(config)#interface serial 0/0/0

Todd(config-if)#

This can look a little dicey, I know, but I promise it’s really not that hard! It helps to remem-

ber that you should always view a running-config output first so you know what interfaces

you have to deal with. Here’s my 2801 output:

Todd(config-if)#do show run
