Configuring Link Aggregation

47

Creating or Deleting an Aggregation Group

You can use the following command to create a manual aggregation group or static LACP aggregation group, but the dynamic LACP aggregation group is established by the system when LACP is enabled on the ports. You can also delete an existing aggregation group: when you delete a manual aggregation group, all its member ports are disaggregated; when you delete a static or dynamic LACP aggregation group, its member ports form one or several dynamic LACP aggregation groups.

Perform the following configuration in system view.

Table 40 Create or Delete an Aggregation Group

Operation

Command

 

 

Create an aggregation group

link-aggregation group agg-idmode

 

{ manual static }

Delete an aggregation group

undo link-aggregation group

 

agg-id

 

 

During creating an aggregation group, if it already exists in the system but contains no member port, it changes to the new type; if it already exists in the system and contains member ports, then you can only change a dynamic or static LACP aggregation group to a manual one, or a dynamic LACP aggregation group to a static one. In the former case, LACP shall be disabled at the member ports automatically, while in the latter case, LACP shall remain enabled.

Adding or Deleting Ethernet Ports to or from an Aggregation Group

You can add/delete ports into/from a manual or static LACP aggregation group, but the addition or deletion of member port for a dynamic LACP aggregation group is automatic.

Perform the following configuration in corresponding view.

Table 41 Add/Delete Ethernet Port to/from Aggregation Group

Operation

Command

 

 

Add an Ethernet port into the aggregation

port link-aggregation group agg-id

group (Ethernet port view)

 

Delete an Ethernet port from the aggregation

undo port link-aggregation group

port (Ethernet port view)

 

Aggregate Ethernet ports (System view)

link-aggregation interface_name1

 

to interface_name2 [ both ]

 

 

Note that:

You cannot enable LACP at the mirrored port, port with static MAC address configured, port with static ARP configured, port with 802.1x enabled.

You must delete the aggregation group, instead of the port, if the manual or static LACP aggregation group contains only one port.
