Spanning Tree Advanced


STP Setup

Hello Time[sec]
The time between Configuration BPDU packets in seconds. This is the same value as the Bridge Hello Time of the Root Bridge, and is used for all the Bridges in a network.

Forward Delay[sec]
The time the Bridge spends in the Listening State when moving from the Blocking State to the Learning State that the Bridge spends in the Learning State when moving from the Listening State to the Forwarding State. This is the same value as Forward Delay of the Root Bridge, and is used for all the Bridges in a network.

Max Age[sec]
The maximum age acceptable by the Bridge for information obtained from a Configuration Bridged Protocol Data Unit (BPDU). This is the same value as the Bridge Max Age of the Root Bridge and is used for all the Bridges in a network.

Aging Time[sec]
The maximum time that learned unicast entries in the forwarding table are retained. This is NOT defined by the Root Bridge. The Ageing Time is normally the same as the Bridge Aging Time; in special situations it is equal to the Forward Delay for the Bridge (refer to IEEE 802.1D).


STP Topology

Topology age
Days, hours, minutes, and seconds since the topology has changed.

Topology change time
Defined by the Spanning tree Standard. Refer to the IEEE 802.1D for further information.

Topology change count
The number of network topology changes made since the switch was last reset or the statistics were reset.


Bridge Setup

Bridge hello time[sec]
The Hello Time configured for this Bridge. The Bridge hello time is used when the Bridge is the Root bridge.

Bridge forward delay[sec]
The Forward Delay configured for this Bridge. The Bridge forward delay is used when the Bridge is the Root bridge.

Bridge max age[sec]
The Bridge Max Age configured for this Bridge. The Bridge Max Age is used when the Bridge is the Root bridge.
