Bridge Max Age - Specifies the bridge max age for the Common and Internal Spanning tree (CST). The value lies between 6 and 40, with the value being less than or equal to "2 * (Bridge Forward Delay - 1)" and greater than or equal to "2 * (Bridge Hello Time + 1)". The default value is 20.

Bridge Hello Time - Specifies the bridge hello time for the Common and Internal Spanning tree (CST), with the value being less than or equal to "(Bridge Max Age / 2) - 1". The default hello time value is 2.

Bridge Forward Delay- Specifies the time spent in "Listening and Learning" mode before forwarding packets. Bridge Forward Delay must be greater or equal to "(Bridge Max Age / 2) + 1". The time range is from 4 seconds to 30 seconds. The default value is 15.

Spanning Tree Maximum Hops- Configure the maximum number of hops for the Spanning tree.

Non-Configurable Data

Bridge identifier - The bridge identifier for the CST. It is made up using the bridge priority and the base MAC address of the bridge.

Time since topology change - The time in seconds since the topology of the CST last changed. Topology change count - Number of times topology has changed for the CST.

Topology change - The value of the topology change parameter for the switch indicating if a topology change is in progress on any port assigned to the CST. It takes a value if True or False.

Designated root - The bridge identifier of the root bridge. It is made up from the bridge priority and the base MAC address of the bridge.

Root Path Cost - Path Cost to the Designated Root for the CST. Root Port - Port to access the Designated Root for the CST. Max Age - Path Cost to the Designated Root for the CST.

Forward Delay - Derived value of the Root Port Bridge Forward Delay parameter. Hold Time - Minimum time between transmission of Configuration BPDUs.

CST Regional Root - Priority and base MAC address of the CST Regional Root. CST Path Cost - Path Cost to the CST tree Regional Root.

Command Buttons

Submit - Applies the new configuration and causes the changes to take effect. These changes will not be retained across a power cycle unless a save configuration is performed.

Refresh - Refreshes the screen with most recent data.
