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.
