Description: Manages bandwidth allocation and rate limiting within the Cisco CDS-TV content delivery system for video-on-demand services.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-CDSTV-BWMGR-MIB?

CISCO-CDSTV-BWMGR-MIB manages the Bandwidth Manager component of the Cisco Content Delivery System for TV (CDS-TV), a product family delivering ingest, storage, caching, streaming, and video-on-demand to television/set-top-box clients, placing it in the video/content-delivery technology area. It exposes configuration data for the Bandwidth Manager's network address and port, and for thread pool sizing (database, server, and sync thread pools) that governs how many concurrent operations the master streamer can handle. This is relevant to monitoring the software resource status of the Bandwidth Manager process: an admin can check thread pool configuration against observed load and watch for sync alarms that indicate the Bandwidth Manager has lost synchronization with peer components, both of which affect the CDS-TV system's ability to allocate streams and VOD network resources reliably. The MIB is largely self-contained to the CDS-TV product and does not appear to extend a standard IETF MIB, though it interoperates with the broader CDS-TV Cache Control Protocol (CCP) architecture referenced in its description. It is deployed on Cisco CDS-TV master streamer servers in cable/telco video-on-demand and TV content delivery networks. Network engineers evaluating or troubleshooting this functionality can download the CISCO-CDSTV-BWMGR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-CDSTV-BWMGR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco CDS-TV (Content Delivery System for TV) master streamer servers

Monitoring Examples

An admin would poll cdstvBWMgrAddressType/cdstvBWMgrAddress and cdstvBWMgrPort to confirm the Bandwidth Manager is reachable at its expected network location, then check cdstvBWMgrDatabaseThreadPool, cdstvBWMgrServerThreadPool, and cdstvBWMgrSyncThreadPool sizes against observed VOD session load to identify thread pool exhaustion as a cause of stream allocation delays. A raised cdstvBWMgrSyncAlarm would reveal that the Bandwidth Manager has failed to synchronize state with other CDS-TV components, a likely cause of inconsistent bandwidth allocation across the video delivery network. Notifications would surface via ciscoCdstvBWMgrMIBNotifs.

database/server/sync thread pool sizes
sync alarm status
allocated VOD streams/network resources

ciscoCdstvBwmgrMIB	1.3.6.1.4.1.9.9.749			This MIB module defines Bandwidth Manager configuration objects that facilitate the management of the Cisco Content Delivery System for TV (CDS-TV) product family. CDS-TV is a suite of products and software applications providing ingest, storage, caching, streaming, playout and on-demand delivery of video to television or set-top-box clients. The Bandwidth Manager runs on the master streamer and keeps track of allocated streams and VOD network resources. Abbreviations: CCP Cache Control Protocol CDS Content Delivery System CORBA Common Object Request Broker Architecture ISA Interactive Services Architecture ISV Integrated Streamer-Vault FSI File Service Interface FTP File Transfer Protocol MPEG Motion Picture Experts Group MSA Managed Services Architecture RTSP Real-Time Streaming Protocol SOAP Simple Object Access Protocol STB Set-Top Box VOD Video On-Demand Common terms: Catcher: Device responsible for receiving content (typically via satellite dishes and antennae) from content providers or from a Headend-In-The-Sky. Content Ingest: Acquisition of content from a source such as a catcher or an FTP server for storing it locally and making it available to streamers as needed. Device Roles: Vault: Content delivery application responsible for ingesting and storing video content and making it available to streamers and/or caching nodes. Caching Nodes: Content delivery application responsible for caching content from vault (using CCP) and then streaming content out to streamers over HTTP or CCP. Streamer: Content delivery application responsible for streaming video out to STB's. ISV: Content delivery application capable of acting as both a vault and as a streamer in a single device.

IPt cdstvBWMgrAddressType	1.3.6.1.4.1.9.9.749.1.1	InetAddressType	read-write	This object specifies the type of address used by the Bandwidth Manager. The address is specified by cdstvBWMgrAddress.
IP cdstvBWMgrAddress	1.3.6.1.4.1.9.9.749.1.2	InetAddress	read-write	This object specifies the address used by the Bandwidth Manager. The type of the address is specified by cdstvBWMgrAddressType.
INE cdstvBWMgrPort	1.3.6.1.4.1.9.9.749.1.3	InetPortNumber	read-write	This object specifies the port number to listen on for incoming connections from the RTSP server.
U32 cdstvBWMgrDatabaseThreadPool	1.3.6.1.4.1.9.9.749.1.4	Unsigned32	read-write	This object specifies the maximum number of threads in the database connection pool.
U32 cdstvBWMgrServerThreadPool	1.3.6.1.4.1.9.9.749.1.5	Unsigned32	read-write	This object specifies the maximum number of threads in the Bandwidth Manager server pool that are used to process RTSP requests for the duration of the connection.
U32 cdstvBWMgrSyncThreadPool	1.3.6.1.4.1.9.9.749.1.6	Unsigned32	read-write	This object specifies the maximum number of threads available to synchronize sessions with the RTSP during a synchronization operation.

The alarm is generated if the synchronization between RTSP client and server (typically, streamer and back-office, but varies by CDS deployment environment) fails. Note that this does not generate an SNMP notification.
