MSTI ID Displays the MSTI ID previously set by the user.
Type This field allows the user to choose a desired method for altering the MSTI settings.
The user has four choices.
• Add - Select this parameter to add VIDs to the MSTI ID, in conjunction with
the VID List parameter.
• Remove - Select this parameter to remove VIDs from the MSTI ID, in conjunction
with the VID List parameter.
• Delete - Select this parameter to delete this MSTI ID.
• Set Priority Only - Select this parameter to set the priority for the MSTI ID.
This field is used in conjunction with the Priority field.
VID List (1-4094) This field is used to specify the VID range from configured VLANs set on the Switch
that the user wishes to add to this MSTI ID. Supported VIDs on the Switch range from
ID number 1 to 4094. This parameter can only be utilized if the Type chosen is Add or
Remove.
Priority (0-61440) Select a value between 0 and 61440 to specify the priority for a specified MSTI for
forwarding packets. The lower the value, the higher the priority. This entry must be
divisible by 4094 and can only be utilized if the Type chosen is Set Priority Only.
Click Apply to implement changes made.
MSTI Settings
This window displays the current MSTI configuration settings and can be used to update the port
configuration for an MSTI ID. If a loop occurs, the MSTP function will use the port priority to select
an interface to put into the forwarding state. Set a higher priority value for interfaces to be selected for
forwarding first. In instances where the priority value is identical, the MSTP function will implement
the lowest MAC address into the forwarding state and other interfaces will be blocked. Remember that
lower priority values mean higher priorities for forwarding packets.
