stpState

Enables or disables the Spanning Tree Protocol (STP) on your system. 

Valid Minimum Abbreviation

b sp stps

Important Considerations

■

The state of STP is configured in two places: the entire bridge (this 
command) and individual bridge ports. (See Chapter 10.) The 
combination of the states determines the forwarding behavior of each 
port, as shown in the following table:

■

After you enable STP, the system takes several seconds to process the 
command before the Administration Console menu reappears.

■

Although bridge-wide STP is initially disabled, default values exist for 
the following STP bridge parameters: priority, max age, hello time, 
forward delay, and group address. These values do not function until 
STP is enabled.

■

CoreBuilder

®

 3500 and CoreBuilder 9000 Layer 3 modules include an 

ignore STP mode

 option. See Chapter 14

 

in this guide or see your 

system 

Implementation Guide

 for more information.

■

Bridge-wide STP must be disabled on a CoreBuilder 9400 switch if you 
configure it as a MultiPoint Link Aggregation (MPLA) core switch. For 
more information about MPLA, see the 

CoreBuilder 9400
