SET STP
Syntax
set stp [default] [priority=priority]
[hellotime=hellotime] [forwarddelay=forwarddelay]
[maxage=maxage]
Parameters
default Disables STP and returns all bridge and port STP
settings to the default values. This parameter cannot
be used with any other command parameter and can
only be used when STP is disabled. (This parameter
performs the same function as the PURGE STP
command.)
priority Specifies the priority number for the bridge. This
number is used in determining the root bridge for
STP. The bridge with the lowest priority number is
selected as the root bridge. If two or more bridges
have the same priority value, the bridge with the
numerically lowest MAC address becomes the root
bridge.
The range is 0 to 61,440 in increments of 4,096. The
range is divided into sixteen increments, as shown in
the following table. You specify the increment that
represents the desired bridge priority value. The
default value is 32,768 (increment 8).
