This MIB module is for the management of N_Port Virtualization or NPV within the framework of N_Port virtualization(NPV) architecture. N_Port virtualization reduces the number of Fibre Channel domain IDs in SANs(Storage Aera Network). Switches operating in the NPV mode do not join a fabric; rather, they pass traffic between NPV core switch links and end-devices, which eliminates the domain IDs for these edge switches. NPV core switch is a fibre channel edge switch connected to one or more NPV devices.
