Topology View - Brocade Communications Systems StoreFabric SN6500B Developer's Manual

Topology view

The Topology View class was introduced in SMI-S 1.3 to increase the performance and reduce the
number of traversals required to discover topology.
The Network Advisor SMI Agent cannot provide a complete topology and its related information
including instances of classes like Brocade_TopologyView, Brocade_SanActiveConnection if one of
the switches involved goes unreachable or unmanageable.
Objectives
The objective is to deliver a class that can be enumerated, gives better performance than
enumerating Brocade_SANActiveConnection(CIM_ActiveConnection), and traverse to each
endpoint to gather data about the link between switch ports or between N_Ports and switchports.
Performance considerations
Performance should be significantly better than the combined performance of enumeration of
Brocade_SANActiveConnection (CIM_ActiveConnection) and traversals to endpoint instances
through CIMClient.associators call.
