mtu 
Use the mtu command to set the maximum transmission unit (MTU) size, in bytes, for frames 
that ingress or egress the interface. You can use the mtu command to configure jumbo frame 
support for physical and port-channel (LAG) interfaces. The MTU size is a valid integer 
between 1522–9216 for tagged packets and a valid integer between 1518–9216 for untagged 
packets.
Note:
To receive and process packets, the Ethernet MTU must include any 
extra bytes that Layer-2 headers might require. To configure the IP 
MTU size, which is the maximum size of the IP packet (IP Header + IP 
payload), see
