Link Aggregation Configuration
1-8
Caution:
A load-sharing aggregation group contains at least two selected ports, however, a
non-load-sharing aggregation group can have one selected port at most and others are
standby ports.
1.2 Link Aggregation Configuration
Caution:
z The following ports cannot be added to an aggregation group: destination ports to
be mirrored to, reflection ports of remote mirroring, ports configured with static MAC
addresses, static-ARP-enabled ports, and 802.1x-enabled ports.
z Ports where the IP-MAC address binding is configured cannot be added to an
aggregation group.
Note that:
1) When creating an aggregation group:
z If the aggregation group you are creating already exists but contains no port, its
type will change to the type you set.
z If the aggregation group you are creating already exists and contains ports, the
possible type changes may be: changing from dynamic or static to manual, and
changing from dynamic to static; and no other kinds of type change can occur.
z When you change a dynamic/static group to a manual group, the system will
automatically disable LACP on the member ports. When you change a dynamic
group to a static group, the system will remain the member ports LACP-enabled.
2) When a manual or static aggregation group contains only one port, you cannot
remove the port unless you remove the whole aggregation group.
1.2.1 Configuring a Manual Aggregation Group
You can create a manual aggregation group through the following operations. And you
can remove an existing manual aggregation group. After that, all the ports in the group
are removed from the group).
A port can only be manually added/removed to/from a manual aggregation group.
Follow these steps to configure a manual aggregation group:
