CIST port parameters are used to modify MRST operation on an individual port basis. CIST
parameters do not affect operation of STP/PVST.
For each port, CIST is turned on by default. Port parameters include:
•
Port priority
•
Port path cost
•
Port Hello time
•
Link type
•
Edge
•
On and off
•
Current port configuration
The port option of MRST is turned on by default.
The following table describes the commands used to configure CIST Port Configuration Menu options.

Description
Configures the CIST port priority. The port priority helps determine which
bridge port becomes the designated port. In a network topology that has
multiple bridge ports connected to a single segment, the port with the
lowest port priority becomes the designated port for the segment. The
range is 0 to 240, in steps of 16 (0, 16, 32...), and the default is 128.
Configures the CIST port path cost. The port path cost is used to help
determine the designated port for a segment. Generally speaking, the
faster the port, the lower the path cost. The default for Gigabit ports is
20000, and for 10Gb ports is 2000.
Configures the CIST port Hello time. The Hello time specifies how often the
root bridge transmits a configuration bridge protocol data unit (BPDU). Any
bridge that is not the root bridge uses the root bridge Hello value. The
range is 1 to 10 seconds, and the default is 2 seconds.
Defines the type of link connected to the port, as follows:
•
auto—Configures the port to detect the link type, and automatically
match its settings.
•
p2p—Configures the port for Point-To-Point protocol.
•
shared—Configures the port to connect to a shared medium (usually a
hub).
The default link type is auto.
