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 10. You specify the increment that represents
the desired bridge priority value. The default value is
32,768, which is increment 8.
