DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide Parameters disable edge network Specifies to set the port to the port fast disabled mode. Specifies to set the port to the port fast edge mode. Specifies to set the port to the port fast network mode. Default By default, this option is edge. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline A port can be in one of the following three port fast modes: • Edge mode - The port will directly change to the spanning-tree forwarding state when a link-up occurs without waiting for the forward-time delay. If the interface receives a BPDU later, its operation state changes to the non-port-fast state. • Disable mode - The port will always be in the non-port-fast state. It will always wait for the forward-time delay to change to forwarding state. • Network mode - The port will remain in the non-port-fast state for three seconds. The port will change to the port-fast state if no BPDU is received and changes to the forwarding state. If the port received the BPDU later, it will change to the non-port-fast state This command should be used with caution. Otherwise, an accidental topology loop and data-packet loop may be generated and disrupt the network operation. Example This example shows how to configure port Ethernet 1/0/7 to the port-fast edge mode. Switch# configure terminal Switch(config)# interface ethernet 1/0/7 Switch(config-if)# spanning-tree portfast edge Switch(config-if)# 98-22 spanning-tree port-priority This command is used to configure the value of the STP port priority on the specified port. It is only used for RSTP and STP versions. Use the no form of this command to revert to the default setting. spanning-tree port-priority PRIORITY no spanning-tree port-priority Parameters PRIORITY Specifies the port priority. Valid values are from 0 to 240. 954
