The MIB module for the management of preferred path. This MIB enables managers to configure and monitor Preferred Path parameters. Preferred path provides a method of routing traffic over the selected paths, not necessarily the preferred shortest path as chosen by routing protocols such as FSPF. This kind of control allows users to choose shortest paths based on characteristics, such as frames received on a selected interface or frames with selected source FC-ID. This feature allows users to ensure paths seperation between switches for different traffic between a host and a target. Glossary: FC-ID - Fibre Channel Identifier. VSAN - Virtual Storage Area Network. fcroute - Fibre Channel route to host or target. FSPF - Fibre Shortest Path First. IVR - Inter-VSAN Routing.
