NOTE:
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.
Follow these steps to configure a Layer 2 dynamic aggregation group:
To do...
Use the command...
Remarks
Enter system view
system-view
—
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.
Create a Layer 2 aggregate
interface and enter the Layer 2
aggregate interface view
interface bridge-aggregation
interface-number
Required
When you create a Layer 2
aggregate interface, the system
automatically creates a Layer 2
static aggregation group
numbered the same.
Configure the aggregation group
to work in dynamic aggregation
mode
link-aggregation mode dynamic
Required
By default, an aggregation group
works in static aggregation mode.
Exit to system view

Enter Layer 2 Ethernet interface

interface
interface-type
interface-number
Assign the Ethernet interface to the
aggregation group
port link-aggregation group
number
Required
Repeat these two steps to assign
more Layer 2 Ethernet interfaces to
the aggregation group.
Assign the port an LACP priority
lacp
port-priority
port-priority
Optional
By default, the LACP priority of a
port is 32768.
Changing the LACP priority of a
port might affect the aggregation
state of the ports in the dynamic
aggregation group.
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).
