Aggregation States Of Member Ports In An Aggregation Group; Operational Key; Configuration Types - HP 6125XLG Configuration Manual

Aggregation states of member ports in an aggregation group

A member port in an aggregation group can be in any of the following aggregation states:
• Selected—A Selected port can forward traffic.
Unselected—An Unselected port cannot forward traffic.
•
Individual—An Individual port can forward traffic as a normal physical port. A port is placed in
•
Individual state when the following conditions are met:
The corresponding aggregate interface is configured as an edge aggregate interface.
The port does not receive LACPDUs from its peer port.

Operational key

When aggregating ports, the system automatically assigns each port an operational key based on port
information, such as port rate and duplex mode. Any change to this information triggers a recalculation
of the operational key.
In an aggregation group, all Selected ports are assigned the same operational key.

Configuration types

Every configuration setting on a port might affect its aggregation state. Port configurations include the
following types:
Attribute configurations—To become a Selected port, a member port must have the same attribute
•
configurations as the aggregate interface.
Attribute configurations made on an aggregate interface are automatically synchronized to all
member ports. These configurations are retained on the member ports even after the aggregate
interface is removed.
Any attribute configuration change might affect the aggregation state of link aggregation member
ports and running services. To make sure that you are aware of the risk, the system displays a
warning message every time you attempt to change an attribute configuration setting on a member
port.
