By default, the description of an
interface is in the format of
interface-name Interface, such as
Bridge-Aggregation1 Interface.
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 for an aggregate interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable the trap function
globally. snmp-agent trap enable [ standard
[ linkdown | linkup ] * ]
Optional.
By default, link state trapping is
enabled globally and on all
interfaces.
3. Enter Layer 2 aggregate
interface view. interface bridge-aggregation
interface-number
N/A
4. Enable link state traps for
the aggregate interface.
enable snmp trap updown
Optional.
Enabled by default.
Setting the minimum number of Selected ports for an
aggregation group
The bandwidth of an aggregate link increases along with the number of selected member ports. To avoid
congestion caused by insufficient Selected ports on an aggregate link, you can set the minimum number
of Selected ports required for bringing up the specific aggregate interface.
This minimum threshold setting affects the aggregation state of both aggregation member ports and the
aggregate interface:
• All member ports change to the Unselected state and the link of the aggregate interface goes down,
when the number of member ports eligible for being selected is smaller than the minimum
threshold.
• When the minimum threshold is reached, the eligible member ports change to the Selected state,
and the link of the aggregate interface goes up.
