SET RSTP
Syntax
set rstp [default] [priority= priority ] [hellotime= hellotime ]
[forwarddelay= forwarddelay ] [maxage= maxage ]
[rstptype|forceversion=stpcompatible|
forcestpcompatible|normalrstp]
Parameters
default Returns all bridge and port RSTP settings to the default
values. This parameter cannot be used with any other
command parameter and only when RSTP is disabled.
(This parameter performs the same function as the
PURGE 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 61,440 in increments of 4,096. The range
is divided into sixteen increments, as shown in
Table 14. You specify the increment that represents the
desired bridge priority value. The default value is
32,768, which is increment 8.
