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.
