> # NP Links

> An NP link is basically an NPIV uplink to a specific end device. NP links are established when the uplink to the NPV core switch comes up; the links are terminated when the uplink goes down. Once the uplink is established, the NPV switch performs an internal FLOGI to the NPV core switch, and then (if the FLOGI is successful) registers itself with the NPV core switch’s name server. Subsequent FLOGIs from end devices in this NP link are converted to FDISCs. For more details refer to the "Internal FLOGI Parameters" topic.

> Server links are uniformly distributed across the NP links. All the end devices behind a server link will be mapped to only one NP link.
