CIST bridge parameters are used only when the switch is in MSTP mode. CIST parameters do not affect operation of STP/PVST.

The following table describes the commands used to configure CIST Bridge Configuration Menu options parameters.

Table 108 CIST Bridge Configuration Menu options

Command

Description

 

 

prior <0-65535>

Configures the CIST bridge priority. The bridge priority parameter controls which bridge on

 

the network is the MSTP root bridge.

 

To make this switch the root bridge, configure the bridge priority lower than all other

 

switches and bridges on your network. The lower the value, the higher the bridge priority.

 

The range is 0 to 65535, and the default is 32768.

 

This command does not apply to RSTP. See the "Bridge Spanning Tree configuration"

 

section for more information.

 

 

mxage <6-40>

Configures the CIST bridge maximum age. The maximum age parameter specifies the

 

maximum time the bridge waits without receiving a configuration bridge protocol data unit

 

before it reconfigures the MSTP network. The range is 6 to 40 seconds, and the default is 20

 

seconds.

 

This command does not apply to RSTP. See the "Bridge Spanning Tree configuration"

 

section for more information.

 

 

fwd <4-30>

Configures the CIST bridge forward delay parameter. The forward delay parameter

 

specifies the amount of time that a bridge port has to wait before it changes from the

 

listening state to the learning state and from the learning state to the forwarding state. The

 

range is 4 to 30 seconds, and the default is 15 seconds.

 

This command does not apply to RSTP. See the "Bridge Spanning Tree configuration"

 

section for more information.

 

 

cur

Displays the current CIST bridge configuration.

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
