! Enable STP

QTECH(config)#spanning-tree

9.2.3 Enable/disable interface STP

Disable STP of specified interface to make the interface not to attend STP calculating. Use

following command in interface configuration mode:

 Enable STP on specified interface

spanning-tree

 Disable STP on specified interface

no spanning-tree

By default, interface STP enables.

For example:

! Disable STP on Ethernet 01

QTECH(config-if-ethernet-0/1)#no spanning-tree

9.2.4 Configure STP mode

Configure it in global configuration mode:

 Configure switch running STP

spanning-tree mode stp

 Configure switch running RSTP

spannning-tree mode rstp

 Configure switch running MSTP

spanning-tree mode mstp

It is defaulted to run rstp.

Example:

! Configure switch running STP

QTECH(config)#spanning-tree mode stp

9.2.5 Configure STP priority

Configure STP priority when STP enables, and the inferior priority of the switch can be the root

bridge. Use following command in global configuration mode:

 Configure STP priority

spanning-tree priority bridge-priority

 Restore default STP priority

no spanning-tree priority

For example:

! Configure the priority of the switch in spanning tree to 36864

QTECH(config)#spanning-tree priority 36864

Caution: If the priorities of all network bridge in switching network are the same, choose

the one with the smallest MAC address to be the root. If STP enables, configuring network

bridge may cause the re-accounting of the STP. By default, the network bridge priority is

32768 and ranges from 0 to 61440 and should be the integrity of 4096.
