R3303-HP HSR6800 Routers Layer 2 - LAN Switching Configuration Guide

11
When the port attribute configurations or class-two configurations of a member port change, the
Selected/Unselected state of all other member ports in the dynamic aggregation group might change.
Load-sharing criteria for link aggregation groups
In a link aggregation group, traffic can be load-shared across the selected member ports based on a set
of criteria, depending on your configuration.
You can choose one or any combination of the following criteria for load sharing:
• Source/Destination MAC addresses
• Source/Destination IP addresses
Alternatively, you can configure the system to perform per-packet load sharing.
Configuration restrictions and guidelines
Follow these guidelines when you configure a link aggregation group:
• To ensure stable aggregation state and service continuity, do not change port attributes or class-two
configurations on any member port. If you must, make sure you understand its impact on the live
network. Any port attribute or class-two configuration change might affect the aggregation state of
link aggregation member ports and ongoing traffic.
• Avoid assigning ports to a static aggregation group that has reached the limit on Selected ports.
These ports will be placed in Unselected state to avoid traffic interruption on the current Selected
ports. However, a device reboot can cause the aggregation state of member ports to change.
