User Manual

Chapter 1. Commands for MSTP 16

www.qtech.ru

1.1.25 spanning-tree mst rootguard

 Command: spanning-tree [mst <instance-id>] rootguard

 no spanning-tree [mst <instance-id>] rootguard

 Function: Enable the rootguard function for specified instance, the rootguard function

forbid the port to be MSTP root port. “no spanning-tree mst <instance-id> rootguard”

disable the rootguard function.

 Parameter: <instance-id>: MSTP instance ID.

 Command mode: Port Mode.

 Default: Disable rootguard function.

 Usage Guide: The command is used in Port Mode, if the port is configured to be a

rootguand port, it is forbidden to be a MSTP root port. If superior BPDU packet is

received from a rootguard port, MSTP did not recalculate spanning-tree, and just set

the status of the port to be root_inconsistent (blocked).If no superior BPDU packet is

received from a blocked rootguard port, the port status will restore to be forwarding.

The rootguard function can maintain a relative stable spanning-tree topology when a

new switch is added to the network.

 Example: Enable rootguard function for port 1/0/2 in instance 0.

 Switch(config)#interface ethernet 1/0/2

 Switch(Config-If-Ethernet1/0/2)#spanning-tree mst 0 rootguard

 Switch(Config-If-Ethernet1/0/2)#



1.1.26 spanning-tree portfast

 Command: spanning-tree portfast [bpdufilter | bpduguard] [recovery <30-3600>]

o no spanning-tree portfast

 Function: Set the current port as boundary port, and BPDU filter、BPDU guard as

specified mode or default mode; the command “no spanning-tree portfast” sets the

current port as non-boundary port.

 Parameter: bpdufilter: configure the border port mode as BPDU filter

 bpduguard: configure the border port mode as BPDU guard

 recovery: configure the border port can be recovered automatically after

implement bpduguard violation operation

 <30-3600>: the recovery time, do not recover it by default

 Command mode: Port Mode

 Default: All the ports are non-boundary ports by default when enabling MSTP.

 Usage Guide: When a port is set to be a boundary port, the port converts its status

from discarding to forwarding without bearing forward delay. Once the boundary port

receives the BPDU, the port becomes a non-boundary port.

 Example: Configure the border port mode as BPDU guard, the recovery time as 60s.

 Switch(config)#interface ethernet 1/0/2

 Switch(Config-If-Ethernet1/0/2)#spanning-tree portfast bpduguard recovery 60

 Switch(Config-If-Ethernet1/0/2)#
