Parameters

agg-id: Aggregation group ID, in the range of 1 to 31. IDs At present, you can configure the static and dynamic aggregation groups only.

Description

Use the link-aggregation group mode command to create an aggregation group.

Use the undo link-aggregation group command to delete an aggregation group.

& Note:

Port aggregation includes manual aggregation, static aggregation and dynamic aggregation.

l In the manual aggregation mode, ports working at different rates can be aggregated. Manual aggregation can be load balancing aggregation if the aggregation resource is available. In this case, if the traffic rate shared by a low-rate port exceeds the maximum rate of the port, packets may be lost.

l In the static aggregation mode, ports working at different rates can also be aggregated. However, the Selected/Standby state of statically aggregated ports is determined by the transmission rate. Only the ports with the maximum rate and in full-duplex mode can be selected to forward traffic, while other standby ports do not forward traffic.

# Create manual aggregation group 22.
