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:
Bridge STP State Port STP State
Disabled Disabled
Enabled
Removed
Enabled Disabled
Enabled
Removed
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
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
Implementation Guide .
