FTOS# clear dampening interface Gi 0/1 FTOS# show interfaces dampening GigabitEthernet0/0 InterfaceStateFlapsPenaltyHalf-LifeReuseSuppressMax-Sup Gi 0/1Up00205001500300 Link Dampening Support for XML View the output of the following show commands in XML by adding | display xml to the end of the command: • show interfaces dampening • show interfaces dampening summary • show interfaces interface x/y Configure MTU size on an Interface The E-Series supports a link Maximum Transmission Unit (MTU) of 9252 bytes and maximum IP MTU of 9234 bytes. 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, FTOS divides the packet into fragments no bigger than the size set in the ip mtu command. In FTOS, MTU is defined as the entire Ethernet packet (Ethernet header + FCS + payload) Since different networking vendors define MTU differently, check their documentation when planing MTU sizes across a network. 442 | Interfaces
