[Initial value]

spanning-tree bpdu-guard disable

[Input mode]

interface mode

[Description]

Sets BPDU guard for the applicable interface.

If this command is executed with the "no" syntax, the setting returns to the default.

[Note]

This command can be specified only for LAN/SFP port and logical interface.

It is not possible to specify this command for a LAN/SFP port that is associated to a logical interface.

If a LAN/SFP port is associated with a logical interface, the setting of this command for the corresponding LAN/SFP port

returns to the default.

If a LAN/SFP port is shutdown by BPDU guard, it can be brought back by executing the no shutdown command for that

interface.

If a logical interface is shutdown by BPDU guard, it can be brought back by executing the shutdown command for that

interface and then executing the no shutdown command.

[Example]

Enable BPDU guard for LAN port #1.

SWR2310(config)#interface port1.1

SWR2310(config-if)#spanning-tree bpdu-guard enable

6.3.9 Set interface path cost

[Syntax]

spanning-tree path-cost path-cost

no spanning-tree path-cost

[Parameter]

path-cost : <1-200000000>

Path cost value

[Initial value]

Use the following values according to the link speed of the interface.

Link speed Path cost value

1000Mbps 20000

100Mbps 200000

10Mbps 2000000

For a logical interface, the path cost value is calculated based on totaling the link speed of each associated LAN/SFP port.
