9.2.12 Configure link type of specified interface

In rstp, the requirement of interface quickly in transmission status is that the interface must be

point to point link not media sharing link. It can specified interface link mode manually and can

also judge it by network bridge.

Configure it in interface configuration mode:

 Configure interface to be point-to-point link

spanning-tree point-to-point forcetrue

 Configure interface not to be point-to-point link

spanning-tree point-to-point forcefalse

 Configure switch auto-detect whether the interface is point-to-point link

spanning-tree point-to-point auto

For example:

! Configure the link connected to Ethernet 0/1 as a point-to-point link

QTECH(config-if-ethernet-0/1)#spanning-tree point-to-point forcetrue

9.2.13 Configure the current port as an edge port

Edge port is the port connecting to the host which can be in transmission status in very short

time after linkup, but once the port receiving STP packet, it will shift to be non-edge port.

Configure it in interface configuration mode:

 Configutr the port to be edge port

spanning-tree portfast

 Configutr the port to be non-edge port

no spanning-tree portfast

For example:

! Configure Ethernet 0/1 as a non-edge port.

QTECH(config-if-ethernet-0/1)#spanning-tree portfast

9.2.14 Configure the speed limit of sending BPDU of specified

interface

Restrict STP occupying bandwidth by restricting the speed of sending BPDU packet. The

speed is determined by the number of BPDU sent in each hello time.

Configure it in interface configuration mode:

 Configure the maximum number of configuration BPDUs sent by interface in each Hello

time to be 2

spanning-tree transit-limit 2

For example:

! Configure the maximum number of configuration BPDUs that can be transmitted by the

Ethernet 0/1 in each Hello time to 2

QTECH(config-if-ethernet-0/1)#spanning-tree transit-limit 2

9.2.15 STP monitor and maintainenance

The displaying information is as following:

 STP status

 BridgeID

 Root BridgeID
