Create a new instance or map VLAN(s) to an existing one
Syntax
spanning-tree instance ist | 1-64 vlan VLAN-ID
Description
Used to create a new instance or map VLAN(s) to an existing one. Each instance must have at least one VLAN mapped to it. The VLANs unmapped from other instances are automatically mapped to the IST instance. Only IST VLANs can be directly mapped to other instances. When VLANs are mapped to an instance, they are automatically unmapped from the instance they were mapped to before. Any MSTP instance can have all the VLANs configured in the switch.
