instance

To create an MST instance and map it to VLANs, use the command instance in MSTP Configuration Mode. The no form of this command deletes the instance and unmaps specific VLANs from the MST instance.

instance { <instance ID (1-64/4094)> } { vlan } { <vlan-range> }

no instance

no instance { <instance ID (1-64/4094)> } { vlan } { <vlan-range> }

Examples

iS5Comm(config)# spanning-tree mode mst

Spanning Tree enabled protocol is RSTP, now RSTP is being shutdown and MSTP is being enabled

iS5Comm(config)# spanning-tree mst configuration

Note:

This how MSTP Configuration Mode is entered.

iS5Comm(config-mst)# instance 1 vlan 2
