Step
1. Enter system view.
2. Enter aggregate
interface or subinterface
view.
3. Configure the
description of the
aggregate interface or
subinterface.
Configuring a dynamic aggregation group to use port speed
as the prioritized criterion for reference port selection
CAUTION:
• Changing reference port selection criteria might cause transient traffic interruption. Make sure
you understand the impact of this task on your network.
• You must perform this task at both ends of the aggregate link so the peer aggregation systems
use the same criteria for reference port selection.
Perform this task to ensure that a dynamic aggregation group selects a high-speed member port as
the reference port. After you perform this task, the priority order of criteria for reference port selection
is device ID > port speed > port ID.
To configure a dynamic aggregation group to use port speed as the prioritized criterion for reference
port selection:
Step
1. Enter system view.
2. Enter aggregate interface
view.
3. Shut down the interface.
4. Specify port speed as the
prioritized criterion for
reference port selection.

Changing reference port selection
criteria might cause transient traffic
interruption. As a best practice,
shut down the aggregate interface
before you make a change.
By default, port ID is the prioritized
criterion for reference port
selection of a dynamic aggregation
group.
