Enabling Link State Trapping for an Aggregate Interface

With the link state trapping function enabled, an aggregate interface generates linkUp trap messages
when its link goes up and linkDown trap messages when its link goes down. For more information, refer
to SNMP Configuration in the System Volume.
Follow these steps to enable link state trapping on an aggregate interface:
To do...
Enter system view
Enable the trap function
globally
Enter aggregate interface
view
Enable link state trapping for
the aggregate interface

Shutting Down an Aggregate Interface

Shutting down or bringing up an aggregate interface affects the aggregation state and link state of ports
in the corresponding aggregation group:
When an aggregate interface is shut down, all selected ports in the corresponding aggregation
group become unselected and their link state becomes down.
When an aggregate interface is brought up, the aggregation state of ports in the corresponding
aggregation group is recalculated and their link state becomes up.
Follow these steps to shut down an aggregate interface:
To do...
Enter system view
Enter aggregate interface view
Shut down the aggregate
interface

Configuring Load Sharing for Link Aggregation Groups

Configuring Load Sharing Criteria for Link Aggregation Groups

You can determine how traffic is load-shared in a link aggregation group by configuring load sharing
criteria. The criteria can be service port numbers, IP addresses, MAC addresses, or receiving ports
carried in packets, or any combination of them.
Use the command...
system-view
snmp-agent trap enable
[ standard [ linkdown | linkup ] * ]
interface bridge-aggregation
interface-number
enable snmp trap updown
Use the command...
system-view
interface bridge-aggregation
interface-number
shutdown
1-12
