Modify TrCRF Spanning-Tree Protocol Configuration
You can change the path cost and priority of a TrCRF.
This dialog box displays the following information:
STP State (dot1dStpPortState)
Current status of this TrCRF within the spanning tree. Possible values are
disabled, blocked, listening, learning, and forwarding.
Cost (dot1dStpPortPathCost)
Cost associated with the TrCRF. The Spanning-Tree Protocol uses path costs to
determine which VLAN to select as a forwarding VLAN. Therefore, lower numbers
should be assigned to VLANs that use faster media (such as full-duplex), and
higher numbers should be assigned to VLANs that use slower media. The possible
range is 1 to 65535. The default is 62. A rule of thumb for the path cost is 1000
/ LAN speed, in megabits per second.
Priority (dot1dStpPortPriority)
Priority associated with the TrCRF. The VLAN with the lowest priority value
has the highest priority and will forward the spanning-tree frames. The possible
range is 0 through 255 (decimal). The default is 128. If all VLANs have the
same priority value, the lowest VLAN ID forwards the spanning-tree frames.
