Item Description
Port-Priority Displays the LACP priority value for the port.
LACP Timeout
Displays the administrative LACP timeout. The possible field values are:

Long: Specifies the long timeout value. This is the default.

Short: Specifies the short timeout value.
Group ID Display LAG ID which the port belongs to. N/A: unassigned.
Configuring STP
STP (Spanning Tree Protocol) is a bridge-based system for providing fault tolerance on networks and can be
used to detect and disable network loops. The spanning tree ensures that the optimal path is maintained
between spanning tree-compliant networked devices by:

Disabling redundant paths when the main paths are operational.
 Enabling redundant paths if the main paths fail.
Spanning tree uses a distributed algorithm to select a bridging device that serves as the root of the spanning
tree network.
The bridging device, known as the Root Bridge, generates bridge protocol data units (BPDUs) on all ports
at a regular interval known as the Hello Time. All other spanning tree-compliant devices on the network have
a designated Root Port. This is the Port nearest the Root Bridge and it is used for receiving the BPDUs
initiated by the Root Bridge. If a bridge does not get a Hello BPDU after a predetermined interval, the bridge
assumes that the link to the Root Bridge is down. This bridge will then initiate negotiations with other bridges
to reconfigure the network to reestablish a valid network topology.
