7.2.1 Viewing a LAN’s STP Statistics
Each access point LAN has the ability to track its own unique STP statistics. Refer to the LAN STP
Stats page when assessing mesh networking functionality for each of the two access point LANs.
Access points in bridge mode exchange configuration messages at regular intervals (typically 1 to 4
seconds). If a bridge fails, neighboring bridges detect a lack of configuration messaging and initiate
a spanning-tree recalculation (when spanning tree is enabled).
To view access point LAN’s STP statistics:
1. Select Status and Statistics -> LAN Stats -> LAN1 Stats (or LAN2 Stats) > STP Stats
from the access point menu tree.
2. Refer to the Spanning Tree Info field to for details on spanning tree state, and root
access point designation.
Spanning Tree State Displays whether the spanning tree state is currently enabled or
disabled. The spanning tree state must be enabled for a unique
spanning-tree calculation to occur when the bridge is powered up
or when a topology change is detected.
Designated Root Displays the access point MAC address of the bridge defined as the
root bridge in the Bridge STP Configuration screen. For information
on defining an access point as a root bridge, see Setting the LAN
Configuration for Mesh Networking Support on page 9-5.
