|
Protocol Type
|
The current operating version of the Spanning Tree Protocol.
|
Priority
|
Sets the Bridge priority--0 to 65,535. The default is 32,768.
Controls which bridge on the network is the STP root bridge. To make the WSM the root bridge, configure the bridge priority lower than all other switches and bridges on your network. The lower the value, the higher the bridge priority.
|
Last Topology Change
|
Time elapsed since a topology change was last detected by the bridge, displayed as days, hours:minutes:seconds.
|
Total Topology Changes
|
Total number of topology changes, detected by the bridge, since the management entity was last reset or initialized.
|
Root Identifier
|
The bridge identifier of the root of the spanning tree. This value is used as the Root Identifier parameter in all configuration bridge protocol data units (PDU) that were originated by this node.
|
Root Cost
|
Cost of the path to the root as seen from this bridge.
|
Root Port
|
Number of the port that offers the lowest-cost path from this bridge to the root bridge.
|
Maximum Age
|
Maximum age (in seconds) of Spanning Tree Protocol information learned from the network, on any port, before it is discarded.
|
Hello Interval
|
Time, in seconds, between the transmission of the configuration bridge PDUs by this node on any port. The time is measured when it is the root of the spanning tree (or trying to become so). The default is 300.
|
Forwarding Delay
|
Time, in seconds, for a port to change its spanning state when moving towards the Forwarding state. Forwarding Delay determines how long the port stays in each of the Listening and Learning states that precede the Forwarding state. This value is also used for aging all dynamic entries in the Forwarding Database, after a topology change has been initiated. The bridge uses this value, unless the bridge becomes the root. In that case, Forwarding Delay becomes the value that all bridges, including this one, will start using when this bridge becomes the root.
|
Root Maximum Age
|
Sets the Maximum bridge age in seconds. When this bridge is acting as the root, all bridges use Maximum Age for Maximum Information Age--600 to 4,000 seconds.
The maximum age specifies the maximum time the bridge waits to receive a configuration bridge protocol data unit (BDPU) before it reconfigures the STP network. The range is 6 to 40 seconds, and the default is 20 seconds.
The value of Maximum Age is an integer. An agent may return a badValue error if the input value is not a whole number.
|
Root Hello Interval
|
Sets the value, in seconds, that all bridges use for Hello Time when this bridge is acting as the root--100 to 1,000 seconds.
The Hello Time specifies how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge hello value. The range is 1 to 10 seconds, and the default is 2 seconds
The value of Bridge Hello Time Period is an integer. An agent may return a badValue error if the input value is not a whole number.
|
Root Forwarding Delay
|
Sets the state change delay value, in seconds as an integer. When this bridge is acting as the root, all bridges use Bridge State Change Delay for State Change Delay--400 to 3,000 seconds.
The forward delay parameter specifies the amount of time that a bridge port has to wait before it changes from the listening state to the learning state and from the learning state to the forwarding state. The range is 4 to 30 seconds, and the default is 15 seconds.
An agent may return a badValue error if the input value is not a whole number.
|
Hold Interval
|
The interval (in units of hundredths of a second) during which no more than two Configuration bridge PDUs shall be transmitted by this node.
|
Tree
|
Sets the Spanning Tree Group for this configuration.
Spanning Tree Group 1 contains all configured VLANs until you assign individual VLANs to other Spanning Tree Groups. See Configuring a Spanning Tree Group.
