CIST port configuration
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 commands.

Description
Displays the current CIST bridge configuration.
Command mode: All
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.
Command mode: Interface port
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 is 20000 for Gigabit
ports.
Command mode: Interface port
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.
Command mode: Interface port
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.
Command mode: Interface port
Enables or disables this port as an edge port. An edge port is not
connected to a bridge, and can begin forwarding traffic as soon as the
link is up. Configure server ports as edge ports (enabled). This command
is disabled by default.
Command mode: Interface port
Enables CIST on the port.
Command mode: Interface port
Disables CIST on the port.
