T2700G-28TQ
JetStream 28-Port Gigabit Stackable L2+ Managed Switch CLI Guide
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:
T2700G-28TQ(config)#interface gigabitEthernet 1/0/2
T2700G-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:
T2700G-28TQ(config)#interface gigabitEthernet 1/0/2
T2700G-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
set itself automatically as ERROR-PORT when receiving BPDU packets with
