1.2.12 Configuring the Current Port as an Edge Port
Edge ports are ports that neither directly connects to other switches nor indirectly
connects to other switches through network segments. After a port is configured as an
edge port, the rapid transition mechanism is applicable to the port. That is, when the
port changes from the blocking state to the forwarding state, it does not have to wait for
a delay.
You can configure a port as an edge port in one of the following two ways.
I. Configure a port as an edge port in system view
Table 1-15 Configure a port as an edge port in system view
Operation Command Description
Enter system view system-view —
Configure the specified
ports as edge ports
stp interface
interface-list edged-port
enable
Required
By default, all the
Ethernet ports of a switch
are non-edge ports.
II. Configure a port as an edge port in Ethernet port view
Table 1-16 Configure a port as an edge port in Ethernet port view
Operation Command Description
Enter system view system-view —
Enter Ethernet port view
interface interface-type
interface-number
—
Configure the port as an
edge port
stp edged-port enable
Required
By default, all the
Ethernet ports of a switch
are non-edge ports.
On a switch with BPDU protection disabled, an edge port becomes a non-edge port
again once it receives a BPDU from another port.
