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 14. 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 in determining 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 242.
