You can configure global or group-specific load-sharing criteria. A link aggregation group preferentially
uses the group-specific load-sharing criteria. If no group-specific load-sharing criteria is available, the
group uses the global load-sharing criteria.
Configuring the global link-aggregation load sharing criteria
Step Command Remarks
1. Enter system view.
system-view N/A
2. Configure the global
link-aggregation
load-sharing criteria.
link-aggregation load-sharing mode
{ { destination-ip | destination-mac |
source-ip | source-mac } * |
per-packet }
The default settings are source and
destination MAC addresses for
Layer 2 traffic and source and
destination IP addresses for Layer 3
traffic.
Global link-aggregation load
sharing criteria configuration
applies to all aggregation groups.
Configuring load-sharing criteria for an aggregation group
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter aggregate interface
view.
• Enter Layer 2 aggregate interface
view:
interface bridge-aggregation
interface-number
• Enter Layer 3 aggregate interface
view:
interface route-aggregation
interface-number
Use either command.
3. Configure the load-sharing
criteria for the aggregation
group.
link-aggregation load-sharing mode
{ { destination-ip | destination-mac |
source-ip | source-mac } * |
per-packet }
The default setting is the global
load-sharing criteria.
Layer 2 aggregate interfaces do
not support the per-packet
keyword.
Enabling local-first load sharing for link aggregation
Use the local-first load sharing mechanism in a multi-device link aggregation scenario to distribute traffic
preferentially across 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 Figure 6.
