Planet SGS-6341 Series - Spanning-Tree Portfast

14-114
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)#
14.1.25 spanning-tree portfast
Command:
spanning-tree portfast [bpdufilter | bpduguard] [recovery <30-3600>]
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)#
