Software Configuration Manual
15-201
Configure the maximum number of configuration BPDUs sent by interface in each Hello time to be number
spanning-tree transit-limit
number
For example :
! Configure the maximum number of configuration BPDUs that can be transmitted by the Ethernet 0/0/1 in
each Hello time to 2
QTECH(config-if-ethernet-0/0/1)#spanning-tree transit-limit 2
15.2.15
STP monitor and maintainenance
15.2.15.1
Display STP status
The displaying information is as following :
·
STP status
·
BridgeID
·
Root BridgeID
·
All kinds of configuration parameter of STP
Use following command in any configuration mode to display STP status globally or on a port :
show spanning-tree interface
For example :
! Display STP configuration
QTECH(config)#show spanning-tree interface ethernet 0/0/1
