View
Any view
Parameters
interface { interface-type interface-number [ to interface-type interface-number ]:
interface-type specifies port type and interface-number specifies port number. You can
specify a port with the first interface-type interface-number or specify a port range with
the interface-type interface-number to interface-type interface-number where the end

Note that since a manual aggregation group cannot get the information of the peer end,
every item of the peer end is displayed as 0, which does not indicate the actual state of
the peer system.

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.
zIn 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.
zIn 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.
