instance. This command can be used only after the VLAN is defined. Use the no instance command
to unmap the VLAN from the MSTP instance.
Usage
Guidelines
The following rules apply:
• VLANs must be created before mapping to instances.
• VLAN instance mapping is removed from the configuration if the underlying VLANs are deleted.
Examples To map a VLAN to an MTSP instance:
switch(conf-mstp)#instance 1 vlan 2, 3
switch(conf-mstp)#instance 2 vlan 4-6
switch(conf-mstp)#instance 1 priority 4096
