Configuration types

Port configurations include attribute configurations and protocol configurations. Attribute configurations affect the aggregation state of the port but the protocol configurations do not.

Attribute configurations

To become a Selected port, a member port must have the same attribute configurations as the aggregate interface. Table 1 describes the attribute configurations.

Attribute configurations

VLAN

VLAN attribute configurations:

  • Permitted VLAN IDs.

  • PVID.

  • Link type (trunk, hybrid, or access).

  • VLAN tagging mode.

For information about VLANs, see "Configuring VLANs."

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.

Protocol configurations

Settings that do not affect the aggregation state of a member port even if they are different from those on the aggregate interface. MAC address learning settings are examples of protocol configurations.

For an aggregation, only the protocol configurations on the aggregate interface take effect. The protocol configurations on the member ports will not take effect until after the ports leave the aggregation group.
