SET MSTP CIST
Syntax
set mstp cist priority= priority
Parameter
priority Specifies the CIST priority number for the switch. The
range is 0 to 61,440 in increments of 4,096. The range
is divided into sixteen increments, as shown in
Table 20. You specify the increment that represents the
desired bridge priority value. The default value is
32,768, which is increment 8.
Description
This command sets the CIST priority number on the switch. This number is
used to determine the root bridge for the bridged network. The bridge with
the lowest priority number acts 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. To view the current CIST priority
number, see “SHOW MSTP” on page 575.
Example
The following command sets the CIST priority value to 45,056, which is
increment 11:
set mstp cist priority=11
