Configure MTU for Physical Ports

You can configure the MTU (maximum transmission unit) at the physical port level for Layer 2, IPv4, and IPv6.

In SLX-OS, you can use the show interface ethernet command to see the MTU configuration for an interface.

Run the efa inventory device interface set-mtu command.
# efa inventory device interface set-mtu --ip 10.x.x.x  
--if-type eth --if-name 0/11,0/12 --mtu 1600 --ip-mtu 700 --ipv6-mtu 1800
