3-9. STP Configuration

The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D)

for avoiding loops in switched networks. When STP is enabled, ensure that only
one path is active between any two nodes on the network at a time. User can
enable Spanning Tree Protocol on switch’s web management and then set up other
advanced items. We recommend that you enable STP on all switches to ensure a
single active path on the network.

3-9-1. STP Status

Function name:

STP Status

Function description:

In the Spanning Tree Status, user can read 12 parameters to know STP
current status. The 12 parameters’ description is listed in the following table.

Parameter description:

STP State:

Show the current STP Enabled / Disabled status. Default is “Disabled”.

Bridge ID:

Show switch’s bridge ID which stands for the MAC address of this switch.

Bridge Priority:

Show this switch’s current bridge priority setting. Default is 32768.

Designated Root:

Show root bridge ID of this network segment. If this switch is a root
bridge, the “Designated Root” will show this switch’s bridge ID.

Designated Priority:

Show the current root bridge priority.

Root Port:

Show port number connected to root bridge with the lowest path cost.

Root Path Cost:

Show the path cost between the root port and the designated port of the
root bridge.

Current Max. Age:

Show the current root bridge maximum age time. Maximum age time is
used to monitor if STP topology needs to change. When a bridge does
not receive a hello message from root bridge until the maximum age time
is counted down to 0, the bridge will treat the root bridge malfunctioned
and issue a Topology Change Notification (TCN) BPDU to all other
bridges.
