Enabling or Disabling IP Routing
If the “No IP Routing” command does not show up in the show run output then IP Routing is enabled. This would
be located in the upper portion of the show run output. Here is an example from a Cisco C4948E and C4948-10GE
where IP Routing is Disabled:

version 12.2
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
service compress-config
!
hostname Switch
!
boot-start-marker
boot-end-marker
