Create instances

You can create multiple MSTP instances and map VLANs. To take full advantage of the MSTP, create multiple MSTIs and map VLANs to them.

  1. Enter an instance number in CONFIGURATION mode.
    spanning tree mst configuration
  2. Enter the MST instance number in MULTIPLE-SPANNING-TREE mode, from 0 to 63. For Z9332F-ON platform, the MULTIPLE-SPANNING-TREE mode is from 0 to 61.
    instance instance-number
  3. Enter the VLAN and IDs to participate in the MST instance in MULTIPLE-SPANNING-TREE mode, from 1 to 4096.
    instance vlan-id

Create MST instances
