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 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. HP 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 BPDU guard function is disabled, the port functions as a non-edge port, even if you configure it as an edge port. You cannot configure edge port settings and loop guard on a port at the same time. Related commands: stp loop-protection.

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 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. HP 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 BPDU
guard function is disabled, the port functions as a non-edge port, even if you configure it as an edge
port.
You cannot configure edge port settings and loop guard on a port at the same time.
