Parameters
None
Description
Use the enable snmp trap updown command to enable link state trapping for the aggregate interface.
Use the undo enable snmp trap updown command to disable link state trapping for the aggregate
interface.
By default, link state trapping is enabled 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 an aggregate interface to generate linkUp/linkDown traps when its link state changes, you must also
enable link state trapping globally with the snmp-agent trap enable [ standard [ linkdown | linkup ] * ]
command.
For more information about the snmp-agent trap enable command, see the Network Management and
Monitoring Command Reference.
Examples
# Enable linkUp/linkDown trap generation on Layer 2 aggregate interface Bridge-Aggregation 1.
<Sysname> system-view
[Sysname] snmp-agent trap enable
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] enable snmp trap updown
interface bridge-aggregation
Syntax
interface bridge-aggregation interface-number
undo interface bridge-aggregation interface-number
View
System view
Default level
2: System level
Parameters
interface-number: Specifies a Layer 2 aggregate interface number, ranging from 1 to 128.
Description
Use the interface bridge-aggregation command to create a Layer 2 aggregate interface and enter the
Layer 2 aggregate interface view.
Use the undo interface bridge-aggregation command to remove a Layer 2 aggregate interface.
When a Layer 2 aggregate interface is created, a Layer 2 aggregation group with the same number is
automatically created. If you remove the Layer 2 aggregate interface, you also remove the Layer 2
aggregation group. At the same time, the member ports of the aggregation group, if any, leave the
aggregation group.
