CIST port configuration

Command: /cfg/l2/mrst/cist/port <port number>

[CIST Port	1	Menu]
prior	- Set port Priority (0-240)
cost	- Set port Path Cost (1-200000000)
hello	- Set CIST port Hello Time (1-10 secs)
link	- Set MSTP link type (auto, p2p, or shared; default: auto)
edge	- Enables or disables this port as an edge port
on	- Turn port's Spanning Tree ON
off	- Turn port's Spanning Tree OFF
cur	- Display current port Spanning Tree parameters

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.

Table 111 CIST Port Configuration Menu options

Command	Description
prior <0-240>	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.
cost <1-200000000>	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.
hello <1-10>	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.
link autop2pshared	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.
