Configure an Aggregation Group

After configuring an aggregation group, you can manage multiple physical ports in a centralized manner. Any configuration on the aggregation group will be applied to each member port.

• ---

  A maximum of 32 ports can join in one aggregation group at the same time.

None

Create an Aggregation Group

The aggregation groups at the two ends of an aggregated link must be configured to the same type. Description can be added to each aggregation group to make it easier for network administrators to distinguish the aggregation groups.

Table 1-9 Creating an Aggregation Group

• ---

  The protocols that are applied in an aggregation group receive and send protocol packets through the root port of the aggregation group. In static aggregation mode, because the member ports between the devices at two ends do not exchange LACPDU packets, the root ports of the two devices may be on different physical links. In this way, other protocol packets on the aggregation group may fail to be received or sent. To prevent this problem, ensure that the root ports of the devices at the two ends are on the same physical link. In dynamic aggregation mode, the member ports of the devices at two ends exchange LACPDU packets. The negotiation between the two member ports ensures that the root ports of the two devices are on the same physical link.
• After an aggregation group is deleted, all the member ports of the aggregation group are removed from the aggregation group, and then the all the member ports adopt the default settings. This may result in loops in the network. Therefore, before deleting an aggregation group, ensure that the spanning tree function has been enabled or ensure that no loop may occur in the network.

Add Ports into the Aggregation Group

When an aggregation group is created, it is only a logic interface which contains no physical port. In this case, the aggregation function does not take effect. The aggregation function takes effect after ports are added to a static aggregation group. The aggregation function takes effect after local or peer ports are added into a dynamic aggregation group.

Table 1-10 Adding a Port into the Aggregation Group

• ---

  Before adding a port into an aggregation group, the aggregation group must have been created; otherwise, an error message is displayed.
• A port can be added one aggregation group at a time.
• After a port is added into an aggregation group, the some existing configurations (such as loopback detection and VLAN) will be removed from the port.
• Some functions (such as loopback detection) cannot be configured on a member port in an aggregation group; otherwise, an error message is displayed.
• If a port is added into a dynamic aggregation group in passive mode, its peer port must be added into the dynamic aggregation group in active mode. Otherwise, the two ports are both in the unselected status and they cannot participate in user service traffic forwarding.
