The path cost setting of a port can affect the role selection of the port. When the path cost of a port is
changed, the system will re-calculate the role of the port and initiate a state transition.

stp edged-port
Syntax
stp edged-port
{

|

}
undo stp edged-port
View
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default level
2: System level
Parameters
enable
: Configures the ports as edge ports.
disable
: Configures the ports as non-edge ports.
Description
Use
stp edged-port enable
to configure the ports as edge ports.
Use
stp edged-port disable
to configure the ports as non-edge ports.
Use
undo stp edged-port
to restore the default.
By default, all ports are non-edge ports.
Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate
interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port
leaves the aggregation group.
If a port directly connects to a user terminal rather than another device or a shared LAN segment,
this port is regarded as an edge port. When the network topology changes, an edge port will not
cause a temporary loop. You can enable the port to transition to the forwarding state rapidly by
configuring it as an edge port. Hewlett Packard Enterprise recommends you to configure ports
directly connecting 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. Therefore, if a port receives a configuration BPDU when the
