Guidelines and Limitations for VMID
• The VMID feature is not supported on Cisco N-Port Virtualizer (Cisco NPV) switches.
• There is no mechanism in the VMID protocol for the VMIS to notify the attached hypervisor HBA driver

back into the fabric. Consequently, local clients will continue to tag the VM traffic with the previous
