MSTP PROPERTIES
1. STP Version: Click “STP Version” drop-down menu to choose “MSTP” from “STP Version”
drop-down list.
2. Region Name: Click in “Region Name” text box to create an MST region and specify a name to it.
MST bridges of a region form different spanning trees for different VLANs. By default, each MST
bridge starts with the region name as its bridge address. This means each MST bridge is a region
by itself, unless specifically added to one.
3. Revision Level: Click in “Revision Level” text box to specify the number for configuration
information. The default value of revision number is 0.
4. Max Hops: Click in “Max Hops” text box to specify the maximum allowed hops for BPDU in an
MST region. This parameter is used by all the instances of the MST. Specifying the max hops for a
BPDU prevents the messages from looping indefinetely in the network. When a bridge receives a
MST BPDU that has exceeded the allowed max-hops, it discards the BPDU.
5. Update Setting: Click “Update Setting” button when you finished MSTP Properties setting.
