Enabling an MISTP Instance

You can enable up to 16 MISTP instances. Each MISTP instance defines a unique spanning tree
topology. MISTP instance 1, the default instance, is enabled by default; however, you must map a VLAN
to it in order for it to be active. You can enable a single MISTP instance, a range of instances, or all
instances at once using the all keyword.
The software does not display the status of an MISTP instance until it has a VLAN with an active
