Figure 85: STP Interface Settings Page

The STP Interface Settings Page contains the following fields:

Interface — The interface for which the information is displayed.

STP Status — Indicates if STP is enabled on the port. The possible field values are:

–Enabled — Enables the STP on the port.

–Disabled — Disables the STP on the port.

Fast Link — Indicates if Fast Link is enabled on the port. If Fast Link mode is enabled for a port, the Port

State is automatically placed in the Forwarding state when the port link is up. Fast Link optimizes the STP protocol convergence. STP convergence can take 30-60 seconds in large networks.

Root Guard — Prevents devices outside the network core from being assigned the spanning tree root.

Port State — Displays the current STP state of a port. If enabled, the port state determines what forwarding action is taken on traffic. Possible port states are:

–Disabled — Indicates that STP is currently disabled on the port. The port forwards traffic while learning MAC addresses.

–Blocking — Indicates that the port is currently blocked and cannot forward traffic or learn MAC addresses. Blocking is displayed when Classic STP is enabled.

Speed — Indicates the speed at which the port is operating.

Path Cost — Indicates the port contribution to the root path cost. The path cost is adjusted to a higher or lower value, and is used to forward traffic when a path is re-routed.

Priority — Indicates the priority value of the port. The priority value influences the port choice when a bridge has two ports connected in a loop. The priority value is between 0 -240. The priority value is determined in increments of 16.

Designated Bridge ID — Indicates the bridge priority and the MAC Address of the designated bridge.

Designated Port ID — Indicates the selected port priority and interface.

Designated Cost — Indicates the cost of the port participating in the STP topology. Ports with a lower cost are less likely to be blocked if STP detects loops.

Forward Transitions — Indicates the number of times the port has changed from Forwarding state to Blocking state.

LAG — Indicates the LAG to which the port belongs.
