A previously configured name set on the Switch to uniquely identify the MSTI (Multiple

 

 

 

 

Spanning Tree Instance). If a configuration name is not set, this field will show the MAC

 

 

 

 

address to the device running MSTP. This field can be set in the STP Bridge Global Set-

 

 

 

 

tings window.

 

 

 

 

 

 

 

Revision Level

 

This value, along with the Configuration Name will identify the MSTP region configured on

This field shows the MSTI IDs currently set on the Switch. This field will always have the

 

 

 

 

CIST MSTI, which may be configured but not deleted. Clicking the hyperlinked name will

 

 

 

 

open a new window for configuring parameters associated with that particular MSTI.

 

 

 

 

 

 

 

Type

 

This field allows the user to choose a desired method for altering the MSTI settings. The

 

 

 

 

user has two choices.

 

 

 

 

Add VID – Select this parameter to add VIDs to the MSTI ID, in conjunction with the VID List

 

 

 

 

parameter.

 

 

 

 

Remove VID – Select this parameter to remove VIDs from the MSTI ID, in conjunction with

 

 

 

 

the VID List parameter.

STP Instance Settings

This table is used to create STP Instance Settings on the Switch. An STP instance may have multiple members with the same MSTP configuration. There is no limit to the number of STP regions in a network but each region only supports a maximum of 16 spanning tree instances (one unchangeable default entry). VIDs can belong to only one spanning tree instance at a time.

To view this window, click L2 Features > Spanning Tree > STP Instance Settings as shown below:

61440.
