Adding a New VoIP Monitor



When you want to test a link from your office to another location, you need  a Cisco router ( IOS version 12.4 or later )  at each end.

Steps to set up the monitor

Using OpManager, you can now monitor the voice and video quality of a 'call path'. Call path is the WAN link between the router in your main office and the one in the branch office that you want to monitor.

Step 1 :  Enable Add (/discover) the router in your LAN to OpManager. And make sure the SNMP read and write community are configured properly, for that router.

Step 2:   Enable SLA responder on the destination device you wish to monitor, Steps are detailed below.

  1. Open a CLI session on the destination router and enable the EXEC mode as follows: 

  2. Start the global configuration mode:

    Router#configure terminal

  3. Enable the IP SLA responder:

    Router(config)#ip sla responder
    Router(config)#ip sla monitor responder
    (Note: Enter any one of the command to enable IP SLA responder as it varies according to the IOS versions.)

  4. Repeat the above steps for all the destination routers on which you want to monitor VoIP performance.

Step 3: Creating the VoIP monitor:
  1. Go to Home-> VoIP Monitors->Configure VoIP Monitor-> Create New, and enter a name for the monitor.
  2. Select the source router from the list of routers discovered in OpManager, and select the relevant interface.
  3. Specify the destination router either by using the 'Search' option to pick from the discovered routers, or use the 'Add' option to specify the IP address of the destination router and submit the details.
  4. You will see the summary of the monitor you are about to configure. Now click 'Apply to device' to submit the details to the device. This will take few seconds to configure.
    Refresh the page after few seconds to see the new monitor. The data will be collected every hour, from the time you have configured.

You can also create the VoIP monitor from the Router snapshot page. To do so, go to Router snapshot page, click on Action tab and select Add VoIP Monitor. Enter the Monitor Name and Destination IP. Click Submit to create the monitor or Click Advanced button to go to Create New VoIP Monitor page and follow the steps from b to d given under Step 3.

To edit any of the configuration details, go to the respective template, make the changes and save the details. When you create a new monitor, the updated values take effect. When the configuration is complete, the router starts collecting the data at the specified frequency 60 seconds ( default value). OpManager updates this statistics (collected data) every hour and the reports are generated after one hour of configuration.  Go through the FAQs section to understand QoS parameters.
