Spanning Tree for TrCRF Screen

When you select the TrCRF & Port Spanning Tree Parameters... item on the Spanning Tree for TrBRF screen, you are presented with a screen showing the TrCRFs that have the currently selected TrBRF as parent. When you select a TrCRF from the list, the screen shown below is displayed.

STP Mode (TrBRF to TrCRF)

Determines the mode of the internal port from this TrCRF to its TrBRF. Possible values are auto, forwarding, blocked. If the parent TrBRF is participating in the spanning tree protocol, then auto is the default, and the protocol will be determined by the parent TrBRF. If the TrBRF is not participating in the spanning tree protocol, then forwarding is the default.

STP Priority

Priority associated with the TrCRF. The TrCRF with the lowest priority value has the highest priority and will forward the spanning tree frames. The default is 128. The possible range is 0 through 255 (decimal).

STP Cost

Cost associated with the TrCRF. The spanning tree protocol uses path costs to determine which CRF to select as a forwarding CRF. Therefore, lower numbers should be assigned to CRFs that use faster media (such as FDX or CrossLink), and higher numbers should be assigned to CRFs that use slower media. The possible range is 1 to 65,535. The default is 62. The recommended path cost is 1000 /LAN speed in Mbps.
