To view the link dampening configuration on an interface, use the show config command.
To view dampening information on all or specific dampened interfaces, use the show interfaces dampening command
from EXEC Privilege mode.

Configure MTU Size on an Interface
Maximum Transmission Unit (MTU) is defined as the entire Ethernet packet (Ethernet header + FCS + payload).
The link MTU is the frame size of a packet, and the IP MTU size is used for IP fragmentation. If the system determines that the
IP packet must be fragmented as it leaves the interface, the system divides the packet into fragments no bigger than the size
set in the ip mtu command.
NOTE:
Because different networking vendors define MTU differently, check their documentation when planning MTU sizes
across a network.
