2.7.5 Configuring MST region and its maximum number of hops

You can configure region information about the ISCOM2600G-HI series switch when it is
running in MSTP mode. The device MST region is determined by the region name, VLAN
mapping table and configuration of MSTP revision level. You can configure current device in
a specific MST region through following configuration.
The MST region scale is restricted by the maximum number of hops. Starting from the root
bridge of spanning tree in the region, the number of forwarding hops decreases by 1 when the
configuration message (BPDU) passes a device; the ISCOM2600G-HI series switch discards
