The Spanning Tree VLAN Table has the following sub-menus/commands:
Tag — The VLAN Tag value . The maximum tag value is 4000.
VLAN Enabled — Specifies if STP is enabled on the VLAN.
Time Since Topology Change — Indicates the amount of time that has passed since the last topological change in the VLAN.
Topology Changes Count — Indicates the total amount of topographic changes in the VLAN since the bridge was initialized or reset. The time is displayed in a day hour minute second format, for example, 3 days 5 hours 10 minutes and 4 seconds.
Designated Root — Specifies the bridge ID that the current bridge considers the root.
Root Cost — The cost of the path from this bridge to the root.
Root Port — Indicates the port number that offers the lowest cost path from this bridge to the Root Bridge. It is significant when the Bridge is not the Root. The default is zero.
Max Age (Sec) — Indicates the amount of time in seconds that the bridge waits before discarding learned information. Identifies the timeout value used by all Bridges. This ensures that each Bridge has a consistent value against which to test the age of stored configuration information.
Hello Time (Sec) — Indicates the amount of time a bridge waits between CMs.
Hold Time (Sec) — Indicates the amount of time between the relaying of configuration messages through a port. The default value is 1 second.
Forward Delay (Sec) — Indicates the amount of time that a port remains in the listening and learning state before forwarding the traffic. This value is also used, when a topology change has been detected and is underway, to age all dynamic entries in the Forwarding Database. Forward Delay ensures that each Bridge uses a consistent value for the Forward Delay Timer when changing the State of a Port to the Forwarding State.
