Chapter 8 Configuring Spanning Tree

Mapping VLANs to an MISTP Instance

When you are using MISTP-PVST+ or MISTP on a switch, you must map at least one VLAN to an
MISTP instance in order for MISTP-PVST+ or MISTP to be active. These sections describe how to
configure MISTP instances:
•

•
To use VLANs 1025–4094, you must enable MAC address reduction. See the
Note

using extended-range VLANs.
To map a VLAN to an MISTP instance, perform this task in privileged mode:
Task
Step 1 Map a VLAN to an MISTP instance.
Step 2 Verify the VLAN is mapped.
This example shows how to map a VLAN to MISTP instance 1 and verify the mapping:
Console> (enable) set vlan 6 mistp-instance 1
Vlan 6 configuration successful
Console> (enable) show spantree mist-instance 1

You can only map Ethernet VLANs to MISTP instances.
At least one VLAN in the instance must have an active port in order for MISTP-PVST+ or MISTP
to be active.
You can map as many Ethernet VLANs as you wish to an MISTP instance.
You cannot map a VLAN to more than one MISTP instance.
