Virtual interface port in reports in Spectrum Report Manager (SRM) or JasperReports

Issue/Introduction

Can virtual interfaces be viewed in reports in Spectrum Report Manager (SRM) - CABI / JasperReports / Jasper

Environment

DX NetOps Spectrum all currently supported releases
CABI JasperServer 7.9.2.x

Resolution

Only physical interfaces are displayed in SRM

SRM uses the value of the ifConnectorPresent attribute from the ifMIB on an interface to determine if the interface is a physical or virtual port.

The ifMIB defines the ifConnectorPresent attribute as follows:

ifConnectorPresent OBJECT-TYPE
 SYNTAX TruthValue {
   true(1),
   false(2)
 }

 ACCESS read-only
 STATUS current

 DESCRIPTION
 "This object has the value 'true(1)' if the interface sublayer has a physical connector and the value 'false(2)' otherwise."
  ::= { ifXEntry 17 }

SRM will only report on interface models where the value of ifConnectorPresent is true(1).

Example: Ad Hoc Reports for Virtual Interfaces

Spectrum collects the data related to virtual interfaces in the SRM database for historical reporting. This allows users to consume that data through ad hoc reports. They can run ad hoc reports against only virtual interfaces or in combination with physical interfaces to get the appropriate information.

Enable Processing for Virtual Interfaces

Before you generate ad hoc reports for virtual interfaces, enable the processing for virtual interfaces.

• For the existing models and devices, enabling the parameter pulls the virtual interfaces after 24 hours of scheduled device polling.
• Only virtual interfaces of SNMP models will be synchronized.

Follow these steps for 22.2.9 and higher:

• Access the Spectrum Report Manager Administration tab.
• Select the  Reporting Manager, Preferences  option. 
  The  Preferences  page appears. 
  
• Locate and set the  Sync Virtual Interfaces  option to  True . This option lets you synchronize the virtual interface models for the devices.
• Click  Update Preferences  to save the preference settings.
