Displaying STP Information
To display STP information for a VLAN, enter a command such as the following:
This example shows STP information for VLAN 4. The line shown in bold type indicates that the VLAN’s STP
configuration is controlled by VLAN 2. This information indicates that VLAN 4 is a member of a topology group
and VLAN 2 is the master VLAN in that topology group.
Displaying Topology Group Information
To display topology group information, enter the following command:
FastIron SuperX Router(config)# show topology-group
Topology Group 3
=================
master-vlan 2
member-vlan none
Common control ports L2 protocol
ethernet 1/1 MRP
ethernet 1/2 MRP
ethernet 1/5 VSRP
ethernet 2/22 VSRP
Per vlan free ports
ethernet 2/3 Vlan 2
ethernet 2/4 Vlan 2
ethernet 2/11 Vlan 2
ethernet 2/12 Vlan 2
Syntax:
show topology-group [<group-id>]
This display shows the following information.

master-vlan
The master VLAN for the topology group. The settings for STP, MRP,
or VSRP on the control ports in the master VLAN apply to all control
ports in the member VLANs within the topology group.
member-vlan
The member VLANs in the topology group.
Common control ports
The master VLAN ports that are configured with Layer 2 protocol
information. The Layer 2 protocol configuration and state of these
ports in the master VLAN applies to the same port numbers in all the
member VLANs.
L2 protocol
The Layer 2 protocol configured on the control ports. The Layer 2
protocol can be one of the following:
•
MRP
•
STP
•
VSRP
FESX424 Router(config)# show span vlan 4
VLAN 4 BPDU cam_index is 14344 and the Master DMA Are(HEX) 18 1A
STP instance owned by VLAN 2
