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.

Registration
