Example Enable the BPDU filter function for port 2: TL-SG2424P(config)# interface gigabitEthernet 1/0/2 TL-SG2424P(config-if)# spanning-tree bpdufilter spanning-tree bpduguard Description The spanning-tree bpduguard command is used to enable the BPDU protect function for a port. With the BPDU protect function enabled, the port will set itself automatically as ERROR-PORT when it receives BPDU packets, and the port will disable the forwarding function for a while. To disable the BPDU protect function, please use no spanning-tree bpduguard command. Syntax spanning-tree bpduguard no spanning-tree bpduguard Command Mode Interface Configuration Mode (interface gigabitEthernet / interface range gigabitEthernet) Example Enable the BPDU protect function for port 2: TL-SG2424P(config)# interface gigabitEthernet 2 TL-SG2424P(config-if)# spanning-tree bpduguard spanning-tree guard loop Description The spanning-tree guard loop command is used to enable the Loop Protect function for a port. Loop Protect is to prevent the loops in the network brought by recalculating STP because of link failures and network congestions. To disable the Loop Protect function, please use no spanning-tree guard loop command. Syntax spanning-tree guard loop no spanning-tree guard loop 117

Example
Enable the BPDU filter function for port 2:
TL-SG2424P(config)#
interface gigabitEthernet
1/0/2
TL-SG2424P(config-if)# spanning-tree bpdufilter
spanning-tree bpduguard
Description
The
spanning-tree bpduguard
command is used to enable the BPDU protect
function for a port. With the BPDU protect function enabled, the port will set itself
automatically as ERROR-PORT when it receives BPDU packets, and the port
will disable the forwarding function for a while. To disable the BPDU protect
function, please use
no spanning-tree bpduguard
command.

spanning-tree guard loop
Description
The
spanning-tree guard loop
command is used to enable the Loop Protect
function for a port. Loop Protect is to prevent the loops in the network brought by
recalculating STP because of link failures and network congestions. To disable
the Loop Protect function, please use
no spanning-tree guard loop
command.
