Information
Table 60 Configure a static LACP aggregation group (Continued)
Operation
Add the port to the
aggregation group
Enable LACP on the port
A dynamic LACP aggregation group is automatically created by the system based on
LACP-enabled ports. The adding and removing of ports to/from a dynamic
aggregation group are automatically accomplished by LACP.
You need to enable LACP on the ports whom you want to participate in dynamic
aggregation of the system, because, only when LACP is enabled on those ports at
both ends, can the two parties reach agreement in adding/removing ports to/from
dynamic aggregation groups.
LACP cannot be enabled on the following types of ports: mirroring port, port with
static MAC address configured, port with static ARP configured, port with 802.1x
enabled.
In addition, enabling LACP on a member port of a manual aggregation group will not
take effect.
