Description
This command is used to enable the Multiple Spanning Tree Protocol
(MSTP) on the selected ports or the switch. By default, MSTP is disabled.
Here are the guidelines for MSTP:
When MSTP is enabled on a port, the port cannot be a mirror port,
authenticator or supplicant port for Port-based authentication.
When MSTP is enabled on a port, the port-security feature on the
port is disabled.
When MSTP is enabled, Bridge Protocol Data Unit (BPDU)
protection is disabled.
To enable MSTP on a trunk port, you must specify all member
ports in the trunk group.
