Object
The MTU for the interface as shown to the higher
interface sub-layer (this value should not include
the encapsulation or header added by the interface).
If IP is operating over the vlan interface (not include
router port), then this value indicates the IP MTU over
this interface.
For changing the MTU of any interface, the interface
must be brought down first - changing MTU while the
interface is administratively up is not permitted.
If not specified during interface creation, a default
value is assigned based on the ifMainType given to
the particular interface.
While configuring for logical VLAN interfaces, care
should be taken to, configure this value as the
lowest of the MTU values of the member ports.
