Configuring A Dynamic Aggregation Group - H3C S5120-SI Series Configuration Manual

To do...
Create a Layer 2 aggregate
interface and enter the Layer 2
aggregate interface view
Exit to system view
Enter Layer 2 Ethernet
interface view
Assign the Ethernet interface to
the aggregation group

Configuring a Dynamic Aggregation Group

To guarantee a successful dynamic aggregation, ensure 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 dynamic aggregation group:
To do...
Enter system view
Set the system LACP priority
Create a Layer 2 aggregate
interface and enter the Layer 2
aggregate interface view
Configure the aggregation
group to work in dynamic
aggregation mode
Exit to system view
Enter Layer 2 Ethernet
interface view
Use the command...
interface bridge-aggregation
interface-number
quit
interface interface-type
interface-number
port link-aggregation group
number
Use the command...
system-view
lacp system-priority
system-priority
interface bridge-aggregation
interface-number
link-aggregation mode
dynamic
quit
interface interface-type
interface-number
1-9
Remarks
Required
When you create a Layer 2
aggregate interface, the system
automatically creates a Layer 2
static aggregation group
numbered the same.

Required
Repeat these two steps to
assign multiple Layer 2
Ethernet interfaces to the
aggregation group.
Remarks
—
Optional
By default, the system LACP
priority is 32768.
Changing the system LACP
priority may affect the
aggregation state of the ports in
a dynamic aggregation group.
Required
When you create a Layer 2
aggregate interface, the system
automatically creates a Layer 2
static aggregation group
numbered the same.
Required
By default, an aggregation
group works in static
aggregation mode.
