The LACP Summary Page contains the following fields: 

Table 3-24 LACP Summary Page item description 

Port-Priority 

Displays the LACP priority value for the port. 

LACP Timeout 

Displays the administrative LACP timeout. The possible field values are: 

z 

Long: Specifies the long timeout value. This is the default. 

z 

Short: Specifies the short timeout value. 

Group ID 

Display LAG ID which the port belongs to. N/A: unassigned. 

 

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: 

z 

Disabling redundant paths when the main paths are operational. 

z 

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. 

After all the bridges on the network have determined the configuration of their ports, each bridge only 

forwards traffic between the Root Port and the ports that are the Designated Bridge Ports for each
