z
A load-sharing aggregation group contains at least two selected ports, but a non-load-sharing
aggregation group can only have one selected port at most, while others are unselected ports.
z
When more than eight load-sharing aggregation groups are configured on a single switch, fabric
ports cannot be enabled on this switch.
z
When no more than eight load-sharing aggregation groups are configured on a single switch, fabric
ports can be enabled on this switch. The aggregation groups added subsequently are all
non-load-sharing aggregation groups. If the fabric ports are disabled, the state of these
non-load-sharing aggregation groups will not be changed automatically. These non-load-sharing
aggregation groups will become load-sharing aggregation groups only after the unselected ports in
these aggregation groups are unplugged and then plugged or the
shutdown
command and then
the
undo shutdown
command are executed.
Link Aggregation Configuration
z
The commands of link aggregation cannot be configured with the commands of port loopback
detection feature at the same time.
z
The ports where the
mac-address max-mac-count
command is configured cannot be added to
an aggregation group. Contrarily, the
mac-address max-mac-count
command cannot be
configured on a port that has already been added to an aggregation group.
z
MAC-authentication-enabled ports and 802.1x-enabled ports cannot be added to an aggregation
group.
z
Mirroring destination ports and mirroring reflector ports cannot be added to an aggregation group.
z
Ports configured with blackhole MAC addresses, static MAC addresses, multicast MAC addresses,
or the static ARP protocol cannot be added to an aggregation group.
z
Ports where the IP-MAC address binding is configured cannot be added to an aggregation group.
z
Port-security-enabled ports cannot be added to an aggregation group.
z
The port with Voice VLAN enabled cannot be added to an aggregation group.
z
Do not add ports with the inter-VLAN MAC address replicating function of the selective QinQ
feature enabled to an aggregation group.
z
Do not add ports with IP filtering enabled to an aggregation group.
z
Do not add ports with ARP intrusion detection enabled to an aggregation group.
z
Do not add ports with source IP addresses/source MAC addresses statically bound to them to an
aggregation group.
Configuring a Manual Aggregation Group
You can create a manual aggregation group, or remove an existing manual aggregation group (after
that, all the member ports will be removed from the group).
