MIB to provide the information about the disjoint IP networks connected to the various gigabit ethernet interfaces in the 'Fabric' and objects to discover the same. It is possible that multiple disjoint IP networks may terminate on a single fibre channel switch in a Fabric. In such a scenario, the iSNS Server has to ensure that the targets returned on a query by iscsi devices are filter based on access control list (specified by the user during configuration) and also based on gigabit ethernet ports which are reachable to the IP network, on which the iscsi device is present. To achieve the above objective, the iSNS server partitions all known gigabit ethernet ports into disjoint sets based on IP reachability by sending discovery packets. Each set is referred to as an IP Network and the gigabit ethernet ports contained therein are referred to as IP Network members. This MIB provides ability to initiate, configure and show discovery results of the IP Networks in the fabric. GLOSSARY: Fabric - The set of physically connected fibre channel switches. WWN - World Wide Name. ISNS - Internet Storage Name Service.
