Use the mtu command to set the interface MTU (Maximum Transmission Unit), which specifies the maximum allowable size, in bytes, of a data packet on the Ethernet port. The mtu command is available from the topology:<named-topology>:l3 context of the CLI for Admin, b@ac, physical, and routed topologies.
576-1500 | Specifies the size, in bytes, of the MTU. |
The following example sets the size of the MTU to 1500 bytes:
