Setting the MTU value for the management port

The ip-mtu command in the bof router ‟management” interface ‟management” context configures the MTU for IP packets transmitted out the interface of the management router instance associated with the management port. The command applies to the SR OS but does not necessarily apply during the boot loader processing.

The operational MTU for the port is set to the lesser of the values configured with the ip-mtu command and the management port MTU. For example, with the port MTU fixed at 1514 bytes and an Ethernet header size of 14 bytes, the MTU of the management port is 1500 bytes (the default operational IP MTU).

If the interface supports IPv6 packets, the command value must be set to 1280 or higher, in accordance with RFC 2460 Internet Protocol, Version 6 (IPv6) Specification.
