STP linkState Changes
The linkState of a port is now a factor in determining the Spanning Tree port 
state. This change helps prevent bridge loops when making network 
connections to previously inactive ports. 
The bridge port summary and the bridge port detail screens include a new 
linkState column. 
To display the bridge information:
1 From the top level of the Administration Console, enter:
bridge port summary
OR
bridge port detail
The system prompts you for slot number(s).
2 Enter the number(s) of the slot(s) or 
all
 to view port parameters for all 
bridges in the system.
The system prompts you for the port type.
3 Enter 
Ethernet
The system prompts you for port number(s).
4 Enter the number(s) of the port(s) or 
all
 to view port parameters for all 
ports on the bridge.
