Some interfaces on a Cisco 6509 switch are "missing" in Availability Manager

Issue/Introduction

• Some interfaces on a Cisco 6509 switch are "missing" in Smarts IP Availability Manager.
  
  
• Few interfaces are showing in interface section and not in port section, does it has any negative impact?

Environment

All supported releases of Smarts.

Cause

Part of the criteria for classifying Interfaces on devices like the Cisco 6509 switch is that they must be assigned IP addresses. In particular, the Cisco 6509 catalyst switch (OID .1.3.6.1.4.1.9.1.283) is qualified to be a hybrid device. This means it is a layer 3 device capable of discovering both interfaces as well as ports. Smarts IP will create interfaces for all those indices which have an underling IP address, and will create ports for those indices which do not have IP addresses. So, some interfaces that appear to be "missed" by Smarts IP are actually created as ports. The code for this is the following:

GA_CompoundDriver::Containment-Cisco-IOS-Switch-Driver {
drivers = {
{"Containment-Create-Interface-Driver", 10},   <<<<<<<<<<<<<<<<<<<< interface created when there is an underlying IP address

{"Containment-Create-Interface-Ext-Driver", 15},
{"Containment-Create-Port-IfDescr-Driver", 20},   <<<<<<<<<<<<<<<<< rest of the indices are created as ports here.
{"Cisco-Check-IpSec-Driver", 25},
{"Containment-IfMIB-Stack-Driver", 30},
{"Containment-IfTable-Driver", 40},
{"Cisco-Vlan-Layering-Driver", 50}

 }

    waitForCompletion = TRUE

}

Resolution

No fix is required. Smarts IP is functioning as designed.
