Default level
2: System level
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.
For an aggregate interface to generate linkUp/linkDown traps when its link state changes, you must enable link state trapping globally with the snmp-agent trap enable [ standard [ linkdown | linkup ] * ] command.
Related commands: snmp-agent trap enable (Network Management and Monitoring Command Reference).
Examples
# Enable linkUp/linkDown trap generation on interface Bridge-Aggregation 1.

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, and any member ports will leave the aggregation group.

Parameters
interface-number: Layer 3 aggregate interface number, in the range 1 to 1024. The router supports up to 240 aggregation groups.
interface-number.subnumber: Subinterface of a Layer 3 aggregate interface. The interface-number argument specifies the main interface number. The subnumber argument specifies the subinterface number and is separated from the main interface number by a dot (.). The value range for the subnumber argument is 1 to 4094.
Description
Use the interface route-aggregation command to create a Layer 3 aggregate interface/subinterface and enter the Layer 3 aggregate interface/subinterface view.
Use the undo interface route-aggregation command to remove a Layer 3 aggregate interface/subinterface.
Upon creation of a Layer 3 aggregate interface, a Layer 3 aggregation group numbered the same is created automatically. Removing the Layer 3 aggregate interface also removes the Layer 3 aggregation group. At the same time, the member ports of the aggregation group, if any, leave the aggregation group.
Removing a Layer 3 aggregate subinterface does not affect the state of the main interface and the corresponding aggregation group.

Parameters
system-priority: LACP priority of the local system, in the range of 0 to 65535. The smaller the value, the higher the system LACP priority.
Description
Use the lacp system-priority command to set the LACP priority of the local system.
Use the undo lacp system-priority command to restore the default.
By default, the system LACP priority is 32768.
A system ID comprises the system LACP priority and the system MAC address. The local system (the actor) negotiates with the remote system (the partner) to determine port state based on the port IDs on the end with the preferred system ID, that is, the smaller system ID.
Examples
# Set the system LACP priority to 64.
<Sysname> system-view
[Sysname] lacp system-priority 64

Parameters
port-priority: Port aggregation priority, in the range of 0 to 65535.
Description
Use the link-aggregation port-priority command to set the aggregation priority of a port.
Use the undo link-aggregation port-priority command to restore the default.
The default aggregation priority of a port is 32768.
A port ID comprises the port aggregation priority and the port number. The local system (the actor) negotiates with the remote system (the partner) to determine port state based on the port IDs (ports with smaller port IDs are preferentially selected) on the end with the preferred system ID.
Examples
# Set the port aggregation priority of GigabitEthernet 4/1/1 to 64.
<Sysname> system-view
[Sysname] interface GigabitEthernet 4/1/1
