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.
Configuring the global load sharing mode for link aggregation groups
Follow these steps to configure the global load sharing mode for link aggregation groups:
To do... Use the command... Remarks
Enter system view

Configure the global link
aggregation load sharing
mode
link-aggregation load-sharing mode
{ destination-ip | destination-mac |
destination-port | ingress-port |
source-ip | source-mac |
source-port } *
Optional
By default, the hash keys
for Layer 2 packets are
source/destination MAC
addresses, and those for
Layer-3 packets are
source/destination IP
addresses.
After you configure this
command, the load
sharing modes in all link
aggregation groups
change accordingly
Configuring a load sharing mode for a link aggregation group
Follow these steps to configure a load sharing mode specific to a link aggregation group:
