Description: Manages QoS policy load balancing group configuration and traffic distribution on Cisco routing platforms.

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-QP-LBG-MIB?

CISCO-QP-LBG-MIB is a Cisco-specific module for cable/video headend equipment that manages QAM-Partition (QP) and Load Balance Group (LBG) parameters, used to distribute video or DOCSIS traffic load across servers in a cable headend. It exposes configuration data such as management and server IP addresses, communication protocol, and keepalive timers, together with operational status objects for each QAM partition and its associated server. From a monitoring standpoint it is primarily a service/process health MIB: cqlqpState and cqlqpServerState reveal whether a load-balancing partition or its backend server is up, down, or unresponsive, and the keepalive timer setting governs how quickly a failure is detected. It does not appear to depend on other standard IETF MIBs beyond the general SNMP framework, being a purely Cisco headend-management extension. It is typically deployed in cable MSO headends on platforms handling QAM/video partitioning and load balancing across server farms. Engineers can download the CISCO-QP-LBG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-QP-LBG-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 cable headend / video delivery platforms (e.g., cBR-8 class devices)

Monitoring Examples

An operator polling cqlqamPartitionTable/cqlqamPartitionEntry would check cqlqpState and cqlqpServerState for a partition identified by cqlqpId, alongside cqlqpMgmtIp and cqlqpServerIp. If cqlqpServerState shows a server as unreachable while cqlqpKeepAliveTime has elapsed with no response, that flags a backend load-balancing server outage requiring failover to a healthy partition. Tracking cqlqpProtocol confirms which control protocol is in use for that partition's communication with its server.

What Can Be Monitored

QAM partition state
load-balance server state
server IP reachability
keepalive timer
management protocol in use

How to Use in IPNetwork Monitor

Example using cqlqpState OID:

Select a Cisco cable headend/video delivery platform as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cqlqpState into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This object specifies the state of the QP. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'active', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.
