Configuring Link Aggregation 39
■ Displaying and Debugging Link Aggregation
Enabling or Disabling LACP at a Port
You should first enable LACP at the ports before performing dynamic aggregation,
so that both parties can agree on adding/deleting the ports into/from a dynamic
LACP aggregation group.
Perform the following configuration in Ethernet port view.
LACP is disabled at the port by default.
Note that:
■ You cannot enable LACP at a
■ Mirrored port
■ Port with a static MAC address configured
■ Port with static ARP configured
■ Port with 802.1x enabled.
■ You cannot enable LACP on a port in a manual aggregation group.
■ You can add a port with LACP enabled to a manual aggregation group, but the
LACP will be disabled on it automatically. However, you can add a port with
LACP disabled into a static LACP aggregation group, and the LACP will be
enabled automatically.
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.
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
