Usage guidelines
If a port directly connects to a user terminal rather than to another device or a shared LAN segment, this
port is regarded 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. HP recommends that you 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. If a port receives a configuration BPDU when the BPDU guard
function is disabled, the port functions as a non-edge port, even if you configure it as an edge port.
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 on only that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect on only 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 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
