Use thespanning-tree forward-timeGlobal Configuration mode command to configure the spanning-tree bridge forward time, which is the amount of time a port remains in the listening and learning states before entering the forwarding state. Use thenoform of this command to restore the default co...
· ROOT—Root guard. · LOOP—Loop guard. · BPDU—BPDU guard. If no spanning tree protection feature is configured or spanning tree protection is not triggered, this field displays NONE. TC-Restriction Status of TC transmission restriction on the port. Role-Restriction Status of port role rest...
The spanning-tree guard command, with the root option, enables root guard on the configuration mode interface. Example This command enables root guard on interface ethernet 5. switch(config)# interface ethernet 5 switch(config-if-Et5)# spanning-tree guard root switch(config-if-Et5)# Loop guar...
To enable root guard on all spanning-tree instances on an interface, use thespanning-tree guard rootcommand in interface switch configuration mode. Root guard prevents the interface from becoming the root port of the device. Use thenoform of this command to disable the root gu...

配置Root Guard: Switch(config-if)# spanning-tree guard root /---启用Root Guard特性---/ 注意,Root Guard和Loop Guard特性不可同时使用,也不要在启用了Uplink Fast特性的端口上启用该特性.该特性一旦配置后,对所有VLAN都生效. 另外,也可以使用Loop Guard技术替代端口(AP)或RP由于单向链路的故障问题成为指定...
spanning-tree guard root: if a port recv superior bpdu from a connected switch then the witch sending superior bpdu will become root. This command prohibits the switch sending superior bpdu's from becoming the root & blocks the port recvng such bpdu's. Once bpdu ceases on this port, it ...
To configure loop guard use the following command: switch (config interface ethernet <inf>)# spanning-tree guard root MSTP Spanning Tree Protocol (STP) is a mandatory protocol to run on L2 Ethernet networks to eliminate network loops and the resulting broadcast storm caused by these loops. Mul...
The no form of this command resets the priority to its default value. The priority value is changed to its default value even if the spanning tree Mode is changed. In RSTP, this value is used during the election of root. In MSTP, this value is used during the electio...
