{ None of the full-duplex ports can be chosen as Selected ports.
{ Only half-duplex ports exist in the group.
• To ensure stable aggregation and service continuity, do not change the operational key or attribute
configurations on any member port.
• When the aggregation state of a local port changes in a dynamic aggregation group, the
aggregation state of the peer port also changes.
• A port that joins a dynamic aggregation group after the Selected port limit has been reached is put
in Selected state if it is more eligible than a current member port.
Load sharing criteria for link aggregation groups
In a link aggregation group, traffic can be load-shared across the Selected member ports based on the
per-flow load sharing criterion. The system classifies traffic flows and forwards packets of the same flow
on the same link by one or any combination of the following criteria:
• Source or destination port number.
• Source or destination IP address.

(Required.) Configuring an aggregation group:
• Configuring a static aggregation group
• Configuring a dynamic aggregation group
(Optional.) Configuring an aggregate interface:
• Configuring the description of an aggregate interface
• Configuring the MTU of a Layer 3 aggregate interface
• Setting the minimum and maximum numbers of Selected ports for an aggregation group
• Configuring the expected bandwidth of an aggregate interface
• Shutting down an aggregate interface
• Restoring the default settings for an aggregate interface
(Optional.) Configuring load sharing for link aggregation groups

Configuring an aggregation group
This section explains how to configure an aggregation group.
Configuration guidelines
When you configure an aggregation group, follow these guidelines:
• Deleting an aggregate interface also deletes its aggregation group and causes all member ports to
leave the aggregation group.
• You must configure the same aggregation mode on the two ends of an aggregate link.
