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.

To do...
Enter system view
Enter Layer 2 aggregate
interface view
Shut down the aggregate
interface
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
