Link Aggregation Configuration 51
A load sharing aggregation group may contain several selected ports, but a
non-load sharing aggregation group can only have one selected port, while others
are standby ports. Selection criteria of selected ports vary for different types of
aggregation groups.
Link Aggregation
Configuration
Link aggregation configuration is described in the following sections:
■ Enabling/Disabling LACP
■ Creating/Deleting an Aggregation Group
■ Adding/Deleting an Ethernet Port into/from an Aggregation Group
■ Setting/Deleting the Aggregation Group Descriptor
■ Configuring System Priority
■ Configuring Port Priority
Enabling/Disabling LACP
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.
By default, LACP is disabled at the port.
Note that:
■ You cannot enable LACP at a
■ stack port
■ mirrored port
■ port with a static MAC address configured
■ port with static ARP configured
■ port with 802.1X enabled
■ port in a manual aggregation group
■ You can add a port with LACP enabled into a manual aggregation group, but
then the LACP will be disabled on it automatically. Or you can add a port with
LACP disabled into a static LACP aggregation group, and then the LACP will be
enabled automatically.
■ The Switch selects the port with the minimum port number as the master port
of the aggregation group. This rule applies to all aggregation groups.
Creating/Deleting an Aggregation Group
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
