Enabling Local-First Load Sharing For Link Aggregation - HP A5120 EI Series Configuration Manual

Any two or all three of these elements – ingress port number, source MAC address, and destination

MAC address
Configuring group-specific load-sharing criteria
Follow these steps to configure load-sharing criteria for a link aggregation group:
To do...
Enter system view
Enter aggregate interface
view
Configure the load-sharing
criteria for the aggregation
group
You can set the following group-specific load-sharing criteria:
Source IP address

Destination IP address

Source IP address and destination IP address

Source MAC address

Destination MAC address

Destination MAC address and source MAC address

CAUTION:
By default, an aggregation group uses the global link-aggregation load sharing criteria. You can
configure the group-specific link-aggregation load-sharing criteria to overwrite the global ones, except
those specified with the destination-port, source-port, or ingress-port keywords.

Enabling local-first load sharing for link aggregation

Use the local-first load sharing mechanism in a cross-switch link aggregation scenario to distribute traffic
preferentially across all member ports on the ingress switch rather than all member ports.
When you aggregate ports on different member switches in an IRF fabric, you can use local-first load
sharing to reduce traffic on IRF links, as shown in
Configuration Guide.
Use the command...
system-view
interface bridge-aggregation
interface-number
link-aggregation load-sharing mode
{ destination-ip | destination-mac |
source-ip | source-mac } *
