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:
