The Cisco IOS supports video monitoring on Cisco 76xx devices and on Cisco ASR 9000 Series devices.
IOS video monitoring, referred to as Vidmon, is implemented through IOS CLI commands.

CMM video monitoring includes support for the Vidmon capability provided in Cisco 7600 series routers
running IOS 12.2(33)SRE and in ASR 9000 Series (Viking) devices running IOS XR 3.9. 1.

The Vidmon support in CMM 3.1 varies for Cisco 7600 series routers and ASR 9000 devices. The Cisco
7600 supports VidMon metrics only on the enhanced service blade (ES+) line cards

CMM implements Vidmon support as follows:

When CMM monitors a video flow using Vidmon, depending on the device that is monitored, CMM
uses two tables: a Media Delivery Index (MDI) table and a Constant Bitrate Flows (CBR) table. The
monitored IOS devices support MDI and CBR as follows:

–

The Cisco 7600 platform supports both MDI and CBR. The Vidmon implementation on Cisco
7600 devices uses a MDI table or a CBR table.

The MDI table contains both Delay Factor (DF) and MDI information. The CBR table contains
DF and Media Rate Variation (MRV) information.

–

ASR 9000 Series devices support only CBR through a CBR table.

When CMM detects a video flow it looks for the presence of an MDI table. If there is an MDI table,
then CMM retrieves DF and Media Loss Rate (MLR) information.
