Configuring a Layer 2 dynamic aggregation group
To guarantee a successful dynamic aggregation, make sure 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.
To configure a Layer 2 dynamic aggregation group:
Ste
p
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 a dynamic
aggregation group.
3. Create a Layer 2 aggregate
interface and enter 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. Exit to system view.
quit N/A
6. Assign a Layer 2 Ethernet
interface to the aggregation
group.
a. interface interface-type
interface-number
b. port link-aggregation
group number
Repeat these two sub-steps to
assign more Layer 2 Ethernet
interfaces to the aggregation
group.
7. Assign the port an
aggregation priority.
link-aggregation port-priority
port-priority
Optional.
By default, the aggregation priority
of a port is 32768.
When the number of ports eligible
for Selected ports exceeds the
maximum number of Selected ports
allowed in a dynamic aggregation
group, 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).
