RSTP


The Rapid Spanning Tree Protocol (RSTP) provides rapid convergence of the spanning tree by assigning port roles and by determining the active topology. The RSTP builds upon the IEEE802.1D STP protocol to select the switch with the highest switch priority as the root switch.


Enable RSTP
Enable RSTP of the switch will allow you to control the RSTP parameters from the bridge point of view.


Property (Bridge Setting)

Priority
Specifies the bridge priority value. When switches or bridges are running STP, each is assigned a priority.The default value is 32768. The port priority value is provided in increments of 4096. For example, 4096, 8192, 12288, etc. The range is 0 to 61440.

Max Age
The max age timer controls the maximum length of time that passes before a bridge port saves its configuration BPDU information.

Forward Delay
Forward delay is a time value, which controls how fast a port changes its state. The value determines how long the port stays in each of the listening and learning states which precede the forward state. This value is also used to age all dynamic entries in the forwarding databases when a topology change has been detected and is underway.


Root Status
The bridge identifier of the root of the spanning tree is determined by the RSTP protocol as executed by this node. The bridge identifier value is used as the root identifier parameter in all configuration bridge BPDUs originated by this node.
