What if I set system mtu jumbo 9198 on a random switch in the

But after a reboot with a new system mtu jumbo, what adverse effects
can I expect if there is a jumbo MTU switch among switches with the

For a switch, there are no adverse effects.

Yes, it needs a reboot on the C3560/3750X platform. The command is:

Colleagues,
I have a network of about twenty C3560X switches switching IP-only traffic.
Soon we will be enabling MPLS on some routers connected to this
network, so the switches will have to handle frames with the MTU

From last time remember when we do changes on C3560X and any previous
models it involves to change system mtu command, and new setting only
apply after reboot (ASIC re-init)

It's a pain that Cisco doesn't enable jumbo MTUs on all switches by

On the 3560 and 3750, it is a global command, and not per interface:
