CISCO-NPORT-VIRTUALIZATION-MIB
The MIB module for the management of N_port Virtualization or NPV within the framework of Cisco's N_port virtualization (NPV) Architecture. N_Port virtualization reduces the number of Fibre Channel domain IDs in SANs. 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. Glossary of terms Used in this MIB: ---------------------------------- SAN - Storage Area Network VSAN - Virtual Storage Area Network, Similar to a VLAN. NPV - N Port Virtualization, a technique using which the number of domain IDs in fibre channel fabric can be reduced, leading to easier management. When operating in this mode, a fibre channel switch (typically, a fabric/blade switch) acts as a HBA with respect to the fibre channel fabric and as a switch with respect to the connected devices. NPV Device - A fibre channel switch working in NPV special mode. NPV Core Switch - A fibre channel edge switch connected to one or more NPV devices. Server - Host connected to the NPV device. Typically, a Blade Server connected to Blade switch in NPV mode in a Blade Chassis. Server Interface - Interface on the NPV Device that connects to end devices(hosts/disks). Also, known as F-port, as it operates in F port mode. External Interface - Interface on the NPV Device that connects to the NPV Core Switch. Also known as NP-port as it operates in NP port mode. Traffic Map - Traffic map is a way to restrict traffic flow from an interface to only a set of interfaces. In NPV device, traffic map can be used to present a server interface to the fibre channel fabric only through one of the valid external interfaces specified in the set of interfaces.
