USING THE WEB MANAGEMENT INTERFACE
To display STP information for a specific port, use the same method as the one described in "Displaying STP
Information for an Entire Device" on page 12-7:
1. Log on to the device using a valid user name and password for read-only or read-write access. The System
configuration panel is displayed.
2. Click on the plus sign next to Monitor in the tree view to display the monitoring options.
3. Select the STP link to display the STP bridge and port parameters.
Displaying the STP State of a Port-Based VLAN
When you display information for a port-based VLAN, that information includes the STP state of the VLAN. Use
either of the following methods to display port-based VLAN information.
USING THE CLI
To display information for a port-based VLAN, enter a command such as the following at any level of the CLI:
BigIron(config)# show vlan
Total PORT-VLAN entries: 2
Maximum PORT-VLAN entries: 16
legend: [S=Slot]
PORT-VLAN 1, Name DEFAULT-VLAN, Priority level0, Spanning tree On
Untagged Ports: (S3)
Untagged Ports: (S3) 17 18 19 20 21 22 23 24
Untagged Ports: (S4)
Untagged Ports: (S4) 18 19 20 21 22 23 24

Uplink Ports: None
PORT-VLAN 2, Name greenwell, Priority level0, Spanning tree Off
Untagged Ports: (S1)
Untagged Ports: (S4)
