Deleting a VLAN to MSTI mapping
You can optionally remove a VLAN to MSTI mapping using the no mstp instance command. To do
so, enter a command such as the following.
PowerConnect(config)#no mstp instance 7 vlan 4 to 7
This command deletes the VLAN to MSTI mapping from the running configuration and triggers an
MSTP reconvergence.
Syntax: no mstp instance <instance-number> vlan <vlan-id> | vlan-group <group-id> ]

<----- VLAN 20 configuration
