stp edged-port
Function
The stp edged-port enable command sets the current port as an edge port.
The stp edged-port disable command sets the current port as a non-edge port.
The undo stp edged-port command restores the default attribute of an edge port.
By default, all the ports on the switching device are non-edge ports.
Parameters
| Parameter | Description | Value |
|---|---|---|
| enable | Sets the current port as an edge port. | - |
| disable | Sets the current port as a non-edge port. | - |
Usage Guidelines
Usage Scenario
On a Layer 2 network running a spanning tree protocol, a port connected to terminals does not need to participate in spanning tree calculation. If the port participates in spanning tree calculation, the network convergence speed will be affected. In addition, status changes of the port may cause network flapping, interrupting user traffic. To address this problem, you can run the stp edged-port enable command to configure the port as an edge port. Then, the port will not participate in the spanning tree calculation. This speeds up network convergence and improves network stability.
Precautions
If a port of a switching device receives a BPDU after being configured as an edge port, the switching device will automatically set the port as a non-edge port and recalculate the spanning tree.
