Interface MTU Settings for Different Interface Types: Example
This example shows that an MTU value is configured on different interface types.
1
Configure an interface MTU configuration group and apply this group:
RP/0/RSP0/CPU0:router# show running group l2tr
group l2tr
interface 'GigabitEthernet0/0/0/3.*'
mtu 1500
!
interface 'GigabitEthernet0/0/0/9\..*'
mtu 1400
!
interface 'GigabitEthernet0/0/0/9\..*' l2transport
mtu 1400
!
end-group
RP/0/RSP0/CPU0:router# show running | inc apply-group
Building configuration...
apply-group l2tr
2
Check the concise view and the inheritance view of the various interfaces:
RP/0/RSP0/CPU0:router# show running interface gigabitEthernet0/0/0/30
interface GigabitEthernet0/0/0/30
!
RP/0/RSP0/CPU0:router# show running inheritance interface gigabitEthernet0/0/0/30
interface GigabitEthernet0/0/0/30
## Inherited from group l2tr
mtu 1500
!
RP/0/RSP0/CPU0:router# show running interface gigabitEthernet0/0/0/9.800
interface GigabitEthernet0/0/0/9.800
encapsulation dot1q 800
!
RP/0/RSP0/CPU0:router# show running inheritance interface gigabitEthernet0/0/0/9.800
interface GigabitEthernet0/0/0/9.800
## Inherited from group l2tr
