The following example creates and enables an STPD named 
Backbone_st. It assigns the Manufacturing VLAN to the STPD. It 
disables STP on ports 1 through 3, and port 4.

create stpd backbone_st

config stpd backbone_st add vlan manufacturing

enable stpd backbone_st

disable stpd backbone_st port 1-3,4

To display STP settings, use the following command:

show stpd {<stpd_name> | all}

This command displays the following information:

■

STPD name

■

Bridge ID

■

STPD configuration information

Sample output from the command is displayed below:

show stpd

Stpd:s0                Stp:DISABLED        Number of Ports:8

Ports: 1,2,3,4,5,6,7,8

Vlans:   Default

BridgeID           80:00:00:e0:2b:00:a4:00

Designated root:   00:00:00:00:00:00:00:00

RootPathCost: 0

MaxAge: 0s         HelloTime: 0s       ForwardDelay: 0s

CfgBrMaxAge: 20s   CfgBrHelloTime: 2s  CfgBrForwardDelay:15s

Topology Change Time: 35s              Hold time: 1s

Topology Change Detected: FALSE        Topology Change:FALSE

Number of Topology Changes: 0

Time Since Last Topology Change: 0s

To display port-specific STP information, use the following command:

show stpd <stpd_name> port <portlist>

This command displays the following:

■
