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
clients of a new VE ID range. For clients to detect a new range, they must query the VMIS again. To
force the clients to query again after a range modification, the user must manually log the FCIDs out and
back into the fabric. Consequently, local clients will continue to tag the VM traffic with the previous
shows how VE ID changes during a VM life cycle:
