system system-tunnel-mtu—Configure the MTU to use on the tunnels that send OMP control traffic between Viptela devices. These tunnels are internal tunnels used by the devices to exchange control traffic. This MTU value is not related to, and has no effect on, interface MTUs.
Generally, you never need to modify the system tunnel MTU. The only case when you might consider configuring this parameter is when you are adjusting the TCP MSS value.
