Introduction
Cisco VAMS 2.0 delivers to service providers real-time, centralized monitoring of headend, backbone, regional, and aggregation networks for broadcast video transport. Cisco VAMS 2.0 provides the framework for a flexible end-to-end assurance platform for video. See the "Solution Requirements" section for descriptions of the solution components and required software versions.
Cisco VAMS 2.0 uses Cisco Multicast Manager (CMM 2.5) with patch 2.5.4 for multicast monitoring and troubleshooting functions and the Cisco ROSA Copernicus Network Management System (NMS) for monitoring of video headend events. Additionally, the Cisco VAMS 2.0 system architecture includes an interface between the Cisco Info Center product suite1 and CMM. Cisco has bundled this interface with the Object Server (central DB) and Webtop (web GUI for event list viewing) from the Cisco Info Center product suite.
The Cisco Info Center product suite includes two additional product components from the IBM Tivoli product suite:
•
•
This combination of Cisco Info Center and Netcool functionality accomplishes two key objectives for Cisco VAMS 2.0. It provides:
•
•
Cisco Info Center contains rules files that specify the rules that define multicast alerts from various sources, such as probes, routers, Digital Content Managers (DCMs), and other network management systems. The rules file contains code that extracts the multicast group and source information from these alerts and provides the operator with a Launch CMM Multicast Trace option.
By integrating CMM and the Cisco ROSA NMS with Cisco Info Center you can view all the alarm conditions and data for service level correlation and analysis. Additionally, for CMM events, you can launch troubleshooting and diagnostic analysis directly from Cisco Info Center.
Cisco VAMS 2.0 supports several third-party probes, including the Bridge Technologies, IneoQuest, Mixed Signals, PixelMetrix, and Tektronix video probes. You can add these video quality monitoring probes to key points in the transport network. Functionally, these probes detect impairments and validate the integrity of the Moving Pictures Expert Group (MPEG) transport stream, which carries video.
The video probes communicate with the Cisco VAMS components as follows:
•
•
Cisco VAMS 2.0 uses Cisco ANA 3.6 Service Pack 3 to build an abstracted network model through a set of virtual network elements (VNEs). Each VNE represents an element in the managed network. Cisco VAMS 2.0 extends the base functions of the Cisco ANA 3.6.3 VNEs for Cisco 7600 Series routers, Cisco Carrier Routing System (CRS-1) devices, Cisco 12000 series routers, and Cisco Catalyst 4948 Series switches. These VNE extensions address the specific requirements of video delivery across the IP network.
Finally, Cisco VAMS 2.0 includes generic VNEs supporting specific video probes; this release includes VNEs for IneoQuest, Mixed Signals, and Tektronix video probes.
See Figure 1 and Figure 2 for an overview of the Cisco VAMS components (the topology shown in the figures are examples). Figure 1 shows Cisco VAMS in the video headend network, and Figure 2 shows Cisco VAMS in a video transport network.

The ROSA Copernicus NMS receives events either directly from the DCM, or, if the ROSA EMS is deployed in the headend network, from the ROSA EMS by way of the ROSA NMS server.

The uninstallation procedure is contained in the User Guide for the Cisco Video Assurance Management Solution 2.0.
Important Notes
This section includes the following topics:
•
Nonclearing Events in Cisco Info Center When Repetitive Alarm Suppression Rule Is Enabled in the ROSA NMS
When a ROSA NMS has the Repetitive Alarm Suppression Rule enabled, events might not clear automatically in Cisco Info Center because this ROSA rule causes the ROSA NMS to generate Summary messages in place of individual alarm messages. These Summary messages use incremented trpMsgID values, so Cisco Info Center cannot associate them with the initial alarm event.
The ROSA Repetitive Alarm Suppression Rule is disabled by default.
The workaround for this issue is to:
•
•
For information on these tasks, see "Ensuring that the Alarm Suppression Rule is Disabled" and "Configuring End Debouncing Timers on the DCM" in chapter 5 of the User Guide for Cisco Video Assurance Management System, 2.0, "Configuring the Components of Cisco Video Management Solution 2.0." The User Guide for Cisco Video Assurance Management System, 2.0 is available online at this location:
http://www.cisco.com/en/US/products/ps9518/products_user_guide_list.html
Incorrect Generation of S, G Threshold High Events in CMM with CLI Polling of Cisco 7600
CMM might incorrectly generate S,G Threshold High events from CLI polling of Cisco 7600 devices following a reconvergence event. This is due to the condition described in CSCsy82569—"Show ip mroute count reports negative pps or > 10 x pps for CBR flows." There is no workaround for this issue; however, the false event will clear when the 7600 internal counters are corrected at the next counter interval.
Limitations and Restrictions
This section contains these topics:
•
•
Java Version for Cisco Info Center Browsers
The IBM TBSM browser must run on JRE 1.4.2 or JRE 1.5. Java versions higher than 1.5 in client web browsers might result in a failure of the Service Viewer and Service Details in the TBSM window.
Cisco Multicast Manager Limitation with Naming Services
Disable any naming service such as Network Information Service (NIS) or NIS+ before running CMM 2.5.4.
Cisco Multicast Manager Trap Limitations
The following Cisco Multicast Manager Normalized traps do not clear their corresponding Threshold Exceeded traps:
'High L2 Port Threshold Exceeded','Low L2 Port Threshold Exceeded','L2 Threshold Normailzed',---'SG Delta Threshold Exceeded','SG Threshold Normalized',---'Multicast Bandwidth Percent High Threshold Exceeded','Multicast Bandwidth Percent Low Threshold Exceeded','Multicast Bandwidth Percent Threshold Normalized',---'High BPS Threshold Exceeded','Low BPS Threshold Exceeded','BPS Threshold Normalized',Cisco ANA processes all Cisco Multicast Manager traps, but currently lacks the capability to correlate threshold normalized traps to their corresponding threshold exceeded traps.
In addition, the following Cisco Multicast Manager traps do not have corresponding clears.
'RP Group Threshold Exceeded',---'RPF Failure Threshold Exceeded',---'High Threshold Exceeded PPS','Low Threshold Exceeded PPS',Open Caveats
Table 3 indicates the open caveats for Cisco VAMS 2.0.
