Configuring an EdgePort

The EdgePort feature enables interfaces to begin forwarding traffic approximately 30 seconds sooner.

In this mode an interface forwards frames by default until it receives a BPDU that indicates that it should behave otherwise; it does not go through the Learning and Listening states. The bpduguard shutdown-on-violation option causes the interface hardware to be shut down when it receives a BPDU. When only bpduguard is implemented, although the interface is placed in an Error Disabled state when receiving the BPDU, the physical interface remains up and spanning-tree drops packets in the hardware after a BPDU violation. BPDUs are dropped in the software after receiving the BPDU violation. This feature is the same as PortFast mode in Spanning Tree.
  • CAUTION: Configure EdgePort only on links connecting to an end station. If you enable EdgePort on an interface connected to a network, it can cause loops.
Dell Networking OS Behavior: Regarding bpduguard shutdown-on-violation behavior:
  • If the interface to be shut down is a port channel, all the member ports are disabled in the hardware.
  • When you add a physical port to a port channel already in the Error Disable state, the new member port is also disabled in the hardware.
  • When you remove a physical port from a port channel in the Error Disable state, the error disabled state is cleared on this physical port (the physical port is enabled in the hardware).
  • You can clear the Error Disabled state with any of the following methods:
    • Perform an shutdown command on the interface.
    • Disable the shutdown-on-violation command on the interface (the no spanning-tree stp-id portfast [bpduguard | [shutdown-on-violation]] command).
    • Disable spanning tree on the interface (the no spanning-tree command in INTERFACE mode).
    • Disable global spanning tree (the no spanning-tree command in CONFIGURATION mode).

To enable EdgePort on an interface, use the following command.

Enable EdgePort on an interface. INTERFACE mode spanning-tree rstp edge-port [bpduguard | shutdown-on-violation][bpdufilter]

Example of Verifying an EdgePort is Enabled on an Interface

To verify that EdgePort is enabled on a port, use the show spanning-tree rstp command from EXEC privilege mode or the show config command from INTERFACE mode.
  • NOTE: Dell Networking recommends using the show config command from INTERFACE mode.

In the following example, the bold line indicates that the interface is in EdgePort mode. 

Dell(conf-if-te-2/0)#show config
                                 !
                                 interface TenGigabitethernet 2/0
                                 no ip address
                                 switchport
                                 
                                 spanning-tree rstp edge-port
                                 shutdown
                                 Dell(conf-if-te-2/0)#
