The command "system mtu 1500" on switches is the default one. Even
when value is changed, it will not be stored in neither running-config
nor startup-config. On Catalyst 3550, this information is stored in a
separate file on the flash. On Catalyst 3560, you can't see it, unless
you do "show system mtu".
This is one of the well-know little gotchas on the actual lab exam.
You *have* to know how to solve this. Hence, when configuring routing
protocols on switches, make sure you know what their MTU is.
