Use stp edged-port to configure a port as an edge port.

Use undo stp edged-port to configure a port as a non-edge port.

Usage guidelines

A port directly connecting to a user terminal rather than another device or a shared LAN segment can be configured as an edge port. In case the network topology changes, an edge port does not cause a temporary loop. You can enable the port to transit to the forwarding state rapidly by configuring it as an edge port. As a best practice, configure ports that directly connect to user terminals as edge ports.

Typically, configuration BPDUs from other devices cannot reach an edge port, because the edge port does not connect to any other device. When BPDU guard is disabled on a port configured as an edge port, the port acts as a non-edge port if it receives configuration BPDUs.

On a port, the loop guard function and the edge port setting are mutually exclusive.

When the command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.

When the command is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate interface.

When the command is configured on a member port in an aggregation group, it takes effect only after the port leaves the aggregation group.

Examples

# Configure Ten-GigabitEthernet 1/0/1 as an edge port.

<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] stp edged-port
