SET RSTP
Syntax
set rstp [default] [priority=priority]
[hellotime=hellotime] [forwarddelay=forwarddelay]
[maxage=maxage]
[forceversion=forcestpcompatible|normalrstp]
Parameters
default Disables RSTP and returns all bridge and port RSTP
settings to the default values. This option performs the
same function as the RESET RSTP command. This
parameter should not be used with any other
command parameter. RSTP must be disabled in order
for you to use this parameter. To disable RSTP, use the
DISABLE RSTP command.
priority Specifies the priority number for the bridge. This
number is used in determining the root bridge for
RSTP. 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 61440 in increments of 4096.
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 32768 (increment 8).
