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. For the standard LCOS SX implementation, the MTU size is a valid integer between 1504-12270 for tagged packets and a valid integer between 1500-12270 for untagged packets.
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 ip mtu.
