Configuring the MTU of a Layer 3 aggregate interface or
subinterface
The maximum transmission unit (MTU) of an interface affects IP packets fragmentation and reassembly on
the interface.

Optional.
The default setting is 1500 bytes.
Enabling link state traps for an aggregate interface
You can configure an aggregate interface to generate linkUp trap messages when its link goes up and
linkDown trap messages when its link goes down. For more information, see
Network Management and
Monitoring Configuration Guide
.
To enable link state traps on an aggregate interface:
Step
