Usage Guidelines

When a port is disabled for MSTP, the port blocks all the VLAN traffic that is controlled by Multiple Spanning Tree Protocol (MSTP) instance and the Common and Internal Spanning Tree (CIST) instances.

You can combine individual Ethernet ports, Ethernet port ranges, LAGs, and LAG ranges in the same command if you wish.

The no form of the command enables MSTP.

Examples

The following example shows how to disable MSTP.

device(config)# mstp disable ethernet 1/2/1
