Operational Key; Configuration Types - HP FlexFabric 12900 Series Configuration Manual

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 exist:
Its aggregate interface is configured as an edge aggregate interface.
The port has not received Link Aggregation Control Protocol Data Units (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. The system displays a warning message every time you try to change
an attribute configuration setting on a member port.

• Protocol configurations—Protocol configurations do not affect the aggregation state of the member
ports, even if they are different from those on the aggregate interface. MAC address learning and
spanning tree settings are examples of protocol configurations.
