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, a port configured as an edge
port functions 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 setting is configured in Layer 2 Ethernet interface view, it takes effect only on that
interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after
the port leaves the aggregation group.
Examples
# Configure GigabitEthernet 1/0/1 as an edge port.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp edged-port

Usage guidelines
When you enable the spanning tree feature, the device operates in STP, RSTP, PVST, or MSTP
mode, depending on the spanning tree mode setting.
When you enable the spanning tree feature, the device dynamically maintains the spanning tree
status of VLANs, based on received configuration BPDUs.
When you disable the spanning tree feature, the device stops maintaining the spanning tree status.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that
interface.
