Configure the short LACP
timeout interval (3 seconds)
on the interface.
lacp period short
By default, the long LACP timeout
interval (90 seconds) is adopted by
the interface. The peer sends
LACPDUs slowly.
Do not configure the short LACP
timeout interval before performing
an ISSU. Otherwise, traffic
interruption will occur during the
ISSU. For more information about
ISSU, see

2.
Set the system LACP priority.
lacp
system-priority
system-priority
By default, the system LACP priority
is 32768.
Changing the system LACP priority
might affect the aggregation state
of the ports in the dynamic
aggregation group.
3.
Create a Layer 3 aggregate
interface and enter Layer 3
aggregate interface view.
interface route-aggregation
interface-number
When you create a Layer 3
aggregate interface, the system
automatically creates a Layer 3
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.

group.
7.
Set the LACP operating mode
on the interface.
•
Set LACP to operate in passive
mode:
