MST Configuration Identification

This windo w allo ws the u ser to configure a MSTI i nstance on th e Switch . Th ese settings will un iquely id entify a m ultiple
spanning tree instance set on the Switch. The Switch in itially 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 following window, click L2 Features > Spanning Tree > MST Configuration Identification:
To modify an entry on the table at the bottom of the window, click the corresponding Edit button. To remove an entry on the table
at the bottom of the window, click the corresponding Delete button.
The window above contains the following information:
Parameter
Configuration Name
Revision Level (0-
65535)
MSTI ID
VID List (1-4094)
(e.g.: 2, 4-6)

Use the drop-down menu to enable or disable the flooding of BPDU packets when STP is
disabled.
Choosing the True parameter designates the port as an edge port. Edge ports cannot create
loops, however an edge port can lose edge port status if a topology change creates a poten-
tial for a loop. An edge port normally should not receive BPDU packets. If a BPDU packet is
received, it automatically loses edge port status. Choosing the False parameter indicates that
the port does not have edge port status. Alternatively, the Auto option is available.
Use the drop-down menu to toggle Restricted Role between True and False. If set to True,
the port will never be selected to be the Root port. The default is False.
This is a per-Bridge parameter in RSTP, but it becomes a per-Port parameter in MSTP. The
default value is 2.

Description
This name uniquely identifies 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 value, along with the Configuration Name, identifies the MSTP region configured on the
Switch.
Enter a number between 1 and 15 to set a new MSTI on the Switch.
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.
