Note

If you want all switches to be in the same MST region, they should all have a software version that supports this enhancement installed, or have the same VLANS configured.

It is likely that switches with a VLAN range configured prior to this enhancement and switches with a VLAN range configured after updating the switch with this enhancement will have different Configuration Digests.

The Common Spanning Tree (CST) will still have the correct root associations.

Operating Notes

■Configuring MSTP on the switch automatically configures the Internal Spanning Tree (IST) instance and places all statically and dynamically configured VLANs on the switch into the IST instance. The spanning-tree instance vlan command creates a new MST instance and moves the VLANs you specify from the IST to the MSTI.

You must map a least one VLAN ID to an MSTI when you create it. You cannot map a VLAN ID to more than one instance. You can create up to 16 MSTIs in a region.

■The no form of the spanning-tree instance vlan command removes one or more VLANs from the specified MSTI. If no VLANs are specified, the no form of the command deletes the specified MSTI.

When you remove a VLAN from and MSTI, the VLAN returns to the IST instance, where it can remain or be re-assigned to another MSTI configured in the region.
