38
{
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 have the same operational key.
Configuration types
Port configurations include attribute configurations and protocol configurations. Attribute
configurations of a link aggregation member port affect its aggregation state.
•
Attribute configurations
—To become a Selected port, a member port must have the same
attribute configurations as the aggregate interface. Table 2 describes the attribute
configurations.
Attribute configuration changes on an aggregate interface are automatically synchronized to all
member ports. If the device fails to synchronize the changes to a Selected port, the port might
become Unselected. For the port to become Selected again, you can modify the attribute
configurations on the aggregate interface or the port. The synchronization failure does not
affect the attribute configuration changes made on the aggregate interface. The configurations
that have been synchronized from the aggregate interface are retained on the member ports
even after the aggregate interface is deleted.
Any attribute configuration change on a member port might affect the aggregation states and
running services of the member ports. The system displays a warning message every time you
try to change an attribute configuration setting on a member port.

Feature Considerations
Port isolation
Indicates whether the port has joined an isolation group and which isolation
group the port belongs to.
VLAN mapping
VLAN mapping configured on the port. For more information about VLAN
mapping, see "
Configuring VLAN mapping ."
VLAN
VLAN attribute configurations include the following:
•
Permitted VLAN IDs.
•
PVID.
•
Link type (trunk, hybrid, or access).
•
VLAN tagging mode.
For information about VLANs, see " Configuring VLANs ."
•
Protocol configurations
—Protocol configurations of a member port do not affect the
aggregation state of the member port. MAC address learning and spanning tree settings are
examples of protocol configurations.
NOTE:
•
The protocol configurations for an aggregate interface take effect only on the current
aggregate interface.
•
The protocol configurations for a member port take effect only when the port leaves its
aggregation group.
