Is there a Cisco cli command to reveal the configured and applied IP MTU on a subinterface other than the
sh run int g0/0/2.#?
sh run int g0/0/2
mtu 9154
no ip address
sh run int g0/0/2.1
encapsulation dot1q 1
ip add 10.0.0.1 255.255.255.0
ip mtu 1400
sh int g0/0/2.1
-snip-
MTU 9154
The cli command sh int g0/0/2.1 shows the configured MTU (not the IP MTU) is the same as the physical interface but doesn't show the IP MTU setting on the subinterface.
Note: I understand the differences between the the MTU and the IP MTU, I would just like to have a command to show what was configured is recognized and used.
My router is an ASR1002-X IOS-XE 15.5
Thanks
Frank
