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.
If you do not know the IP address of the switch, see
Change the default IP address of
the switch on page 13.
The login window opens.
4. Enter the switch’s password in the Password
field.
Port Forwarding 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 as follows:
• Disabled. STP is currently disabled on the port.
The port forwards traf
fic
while learning MAC addresses.
• Blocking. The port is currently blocked and cannot be used to forward
traffic or learn MAC addresses.
• 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 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.
