Configuring MST instance parameters
When you enable MSTP on the switch, a spanning tree instance is enabled automatically. The
switch supports up to 16 configurable MST instances for each VLAN group that you want to operate
as an active topology within the region to which the switch belongs. When creating an instance,
you must include a minimum of one VID. You can add more VIDs later if desired.
Syntax:
[no] spanning-tree instance 1..16 vlan vid [vid..vid]
Configuring MSTP on the switch automatically configures the IST instance and places
all statically and dynamically configured VLANs on the switch into the IST instance.
This command creates a new MST instance (MSTI) and moves the VLANs you specify
from the IST to the MSTI.
