Abstract
Techniques are disclosed for zoning information to be shared with an NPIV proxy device or an NPV device such as a blade switch in a blade chassis. Doing so allows the NPV device to enforce zoning locally for the attached server blades and virtualized systems. The NPV device may learn zoning rules using Fiber Channel name server queries and registered state change notifications. Additionally, the NPV device may snoop name server queries to retrieve zoning information (or state change messages) without using the zoning change protocols and without consuming a Fiber Channel domain from the Fiber Channel fabric.
