Shutting Down an Aggregate Interface
Shutting down or bringing up an aggregate interface affects the selected state of the ports in the
corresponding aggregation group. When an aggregate interface is shut down, all selected ports in its
aggregation group become unselected; when the aggregate interface is brought up, the selected state
of the ports in the corresponding aggregation group is re-calculated.
Follow these steps to shut down an aggregate interface:

shutdown
Required
By default, aggregate interfaces
are up.
After shutting down an aggregate interface, you are recommended not to use the shutdown command
and then the undo shutdown command on the member interfaces of the corresponding link
aggregation group. Otherwise, the member interfaces may be brought up.
Configuring a Load Sharing Mode for Load-Sharing Link
Aggregation Groups
The hash algorithm is adopted to calculate load sharing for load-sharing link aggregation groups. Hash
keys used for calculation could be service port numbers, IP addresses, MAC addresses, incoming
ports, or any combinations of them. One hash key or a combination of multiple hash keys represents a
load sharing mode. You can change the load sharing mode of a link aggregation group for different
types of traffic as needed. For example, for Layer 3 traffic, you can use IP addresses as hash keys for
load sharing calculation.
You can configure a global load sharing mode for all link aggregation groups or a load sharing mode
specific to a link aggregation group as needed.
