MST Configuration Table

The following screens in the MST Configuration Table window allow the user to configure a MSTI instance on the Switch.
These settings will uniquely identify a multiple spanning tree instance set on the Switch. The Switch initially possesses one CIST
or Common Internal Spanning Tree of which the user may modify the parameters for but cannot change the MSTI ID for, and
cannot be deleted. To view the Current MST Configuration Identification window, click Configuration > Spanning Tree >
MST Configuration Table:
The window above contains the following information:
Parameter
Configuration Name
Revision Level
MSTI ID
VID List
Clicking the Add button will reveal the following window to configure:
The user may configure the following parameters to create a MSTI in the Switch.
Parameter Description
MSTI ID Enter a number between 1 and 15 to set a new MSTI on the Switch.
Type Create is selected to create a new MSTI. No other choices are available for this field when
creating a new MSTI.
VID List (1-4094) This field is used to specify the VID range from configured VLANs set on the Switch. Supported
VIDs on the Switch range from ID number 1 to 4094.
Priority (0-61440) Select a value between 0 and 61440 to specify the priority for a specified MSTI for forwarding

Description
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 Settings
window.
This value, along with the Configuration Name will identify the MSTP region configured on
the Switch. This field can also be set in the STP Bridge Global Settings window.
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.
This field displays the VLAN IDs associated with the specific MSTI.
