Link Aggregation Configuration 71
■ Aggregation groups with the minimum master port numbers if they reach the
equal rate with other groups after the resources are allocated to them
When aggregation groups of higher priority levels appear, the aggregation groups of
lower priority levels release their hardware resources. For single-port aggregation
groups, if they can transceive packets normally without occupying hardware
resources, they shall not occupy the resources.
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.
