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 the
following table. 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 181.
Example
The following command sets the CIST priority value to 45,056, which is
increment 11:
set mstp cist priority=11
