no spanning-tree bpduguard
Command Mode
Interface Configuration Mode (interface fastEthernet / interface range
fastEthernet / interface gigabitEthernet / interface range gigabitEthernet/
interface ten-gigabitEthernet / interface range ten-gigabitEthernet)
Example
Enable the BPDU protect function for Gigabit Ethernet port 1/0/2:
T3700G-28TQ(config)#interface gigabitEthernet 1/0/2
T3700G-28TQ(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
Command Mode
Interface Configuration Mode (interface fastEthernet / interface range
fastEthernet / interface gigabitEthernet / interface range gigabitEthernet/
interface ten-gigabitEthernet / interface range ten-gigabitEthernet)
Example
Enable the Loop Protect function for Gigabit Ethernet port 1/0/2:
T3700G-28TQ(config)#interface gigabitEthernet 1/0/2
T3700G-28TQ(config-if)#spanning-tree guard loop

spanning-tree guard root

Description
The spanning-tree guard root command is used to enable the Root Protect
function for a port. With the Root Protect function enabled, the root bridge will
