DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide 78-23 spanning-tree priority This command is used to configure the bridge priority. It is only used for RSTP and STP versions. Use the no form of this command to revert to the default setting. spanning-tree priority PRIORITY no spanning-tree priority Parameters PRIORITY Specifies that the bridge priority and bridge MAC address together forms the Spanning-Tree Bridge-ID, which is an important factor in the Spanning-Tree topology. The range is from 0 to 61440. Default By default, this value is 32768. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline The bridge priority value is one of the two parameters used to select the Root Bridge. The other parameter is system's MAC address. The bridge's priority value must be divisible by 4096 and a smaller number represents a better priority. This configuration will take effect on STP version and RSTP mode. In the MSTP mode, use the command spanning-tree mst priority to configure the priority for an MSTP instance. Example This example shows how to configure the STP bridge priority value to 4096. Switch# configure terminal Switch(config)# spanning-tree priority 4096 Switch(config)# 78-24 spanning-tree tcnfilter This command is used to enable Topology Change Notification (TCN) filtering at the specific interface. Use the no form of this command disable TCN filtering. spanning-tree tcnfilter no spanning-tree tcnfilter Parameters None. Default By default, this option is disabled. 810
