View the STP statistics
You can view information about the number and type of bridge protocol data units (BPDUs)
transmitted and received on each port.
To view the Spanning Tree statistics:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
For information about finding the IP address of the switch, see Access the switch on
page 14.
The Local Device Login page displays.
Port Forwarding State The current STP state of a port. If enabled, the port state determines what
forwarding action is taken on traffic. The options are as follows:
• Disabled. STP is currently disabled on the port. The port forwards traffic
while learning MAC addresses.
• Discarding. The port is currently blocked. The port cannot forward traffic
nor can it learn MAC addresses.
• Manual Forwarding. STP is currently disabled on the port. The port
forwards traffic while learning 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 Each MST bridge port that is enabled is assigned a port role for each spanning
tree. The port role is one of the following: Root Port, Designated Port, Alternate
Port, Backup Port, Master Port, or Disabled Port.
Designated Root The root bridge for the selected MST instance. It is made up using the bridge
priority and the base MAC address of the bridge.
Designated Cost 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.
Designated Bridge The bridge identifier of the bridge with the designated port. It is made up using
the bridge priority and the base MAC address of the bridge.
Designated Port The port identifier on the designated bridge that offers the lowest cost to the
LAN. It is made up from the port priority and the interface number of the port.
