Adding a New VoIP Monitor
When you want to
test a link from your office to another location, you need a
router ( IOS version 12.4 or later ) at each end.
Steps to set up the monitor
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
- Open a CLI session on the destination router and
enable the EXEC mode as follows:
- Start the global configuration mode:
- Enable the IP SLA responder:
(Note: Enter any one of the command to enable IP SLA responder as it
varies according to the IOS versions.)
- Repeat the above steps for all the destination routers
on which you want to monitor VoIP performance.
Step 3: Creating the VoIP monitor:
- Go to Home-> VoIP Monitors->Configure VoIP
Monitor-> Create New, and enter a name for the monitor.
- Select the source router from the
list of routers
discovered in OpManager, and select the relevant interface.
- Specify the destination router either by using the
'Search' option to
pick from the discovered routers, or use the 'Add' option to specify
address of the destination router and submit the details.
- 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.
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
( 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
