According to the DOC CD regarding system MTU

"Note You cannot configure a routing MTU size that exceeds the system
MTU size. If you change the system

MTU size to a value smaller than the currently configured routing MTU
size, the configuration change

is accepted, but not applied until the next switch reset. When the
configuration change takes effect, the

routing MTU size automatically defaults to the new system MTU size."

To best of my understanding, if I have not configured system mtu routing
xxxx command, by default it will change with system mtu xxxx command
after reboot. If I have to control this feature, I have to configure
both of them...

Like

System mtu 1600

System mtu routing 1500

Now system mtu will be changed and mtu for touted ports will not be
changes and stay on default level...

Please advise.

Thanks for help and support in advance

Regards
