Configuring a dynamic aggregation group
To guarantee a successful dynamic aggregation, make sure that the peer ports of the ports aggregated
at one end are also aggregated. The two ends can automatically negotiate the aggregation state of each
member port.
Configuring a Layer 2 dynamic aggregation group
Step Command Remarks
1. Enter system view. system-view N/A
2. Set the system LACP priority. lacp system-priority system-priority
Optional.
By default, the system LACP priority
is 32768.
Changing the system LACP priority
might affect the aggregation state
of the ports in dynamic
aggregation groups.
3. Create a Layer 2 aggregate
interface and enter the Layer
2 aggregate interface view.
interface bridge-aggregation
interface-number
When you create a Layer 2
aggregate interface, the system
automatically creates a Layer 2
static aggregation group
numbered the same.
4. Configure the aggregation
group to operate in dynamic
aggregation mode.
link-aggregation mode dynamic
By default, an aggregation group
operates in static aggregation
mode.
5. Return to system view. quit N/A
6. Assign an Ethernet interface
to the aggregation group.
a. Enter Layer 2 Ethernet
interface view:
interface interface-type
interface-number
b. Assign the Ethernet
interface to the
aggregation group:
port link-aggregation
group number
Repeat this step to assign multiple
Layer 2 Ethernet interfaces to the
aggregation group.
7. Assign the interface an
aggregation priority. link-aggregation port-priority
port-priority
Optional.
By default, the aggregation priority
of a port is 32768.
Changing the aggregation priority
of a port might affect the
aggregation state of the ports in
the dynamic aggregation group.
8. Set the LACP timeout interval
on the port to the short timeout
interval (1 second).
lacp period short
Optional.
By default, the LACP timeout
interval on a port is the long
timeout interval (30 seconds).
