Spanning Tree Tab - STP Interface Settings
The STP Interface Settings screen shows STP properties assigned to individual ports. This screen contains the
following fields:
Port. Specifies the port number on which STP settings are to be to modified.
STP. Enables or disables STP on the port.
Port Fast. 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 mode optimizes the time it takes for the STP protocol to converge. STP
convergence can take 30-60 seconds in large networks.
Root Guard. Indicates that this port cannot be configured as a root port.
Port State - Indicates 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 - STP is currently disabled on the port. The port forwards traffic while learning MAC addresses.
Blocking - The port is currently blocked and cannot be used to forward traffic or learn MAC addresses.
Blocking is displayed when Classic STP is enabled.
Listening - The port is currently in the listening mode. The port cannot forward traffic nor can it learn MAC
addresses.
Learning - The port is currently in the learning mode. The port cannot forward traffic however it can learn new
MAC addresses.
Forwarding - The port is currently in the forwarding mode. The port can forward traffic and learn new MAC
addresses.
Port Role. Indicates the port role assigned by the STP algorithm that provides STP paths. The possible field
values are:
Root-Provides the lowest cost path to forward packets to root switch.
Designated-Indicates that the port via which the designated switch is attached to the LAN.
Alternate-Provides an alternate path to the root switch from the root interface.
