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.
For the standard Unified Switch implementation, 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
"ip mtu" on page
