Description: Manages subscriber and content awareness broadband policy enforcement statistics on Cisco CSG 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-SCAS-BB-MIB?

CISCO-SCAS-BB-MIB is the main SNMP MIB for the Cisco Subscriber and Content Awareness (SCAS) Broadband application, which runs on Cisco Service Control Engine (SCE) platforms used for deep packet inspection and subscriber traffic management. It belongs to Cisco's broadband/service-provider traffic-management product line, exposing per-link and per-service usage statistics for subscriber sessions traversing the SCE. The data it exposes falls into performance/traffic-counter categories: upstream/downstream traffic volume, session counts, session duration, concurrent sessions, active subscribers, and dropped-packet counts per service and per link. For hardware/software status monitoring it is used mainly to track the health and load of the SCE's traffic-classification engine, spotting abnormal drop rates or session-count spikes rather than classic CPU/temperature metrics, though it complements the platform's chassis-health MIBs for overall device status. It typically complements the base CISCO-SCE-MIB and platform hardware MIBs for chassis-level health, and is deployed in service-provider networks where SCE appliances perform subscriber-aware bandwidth management and content policy enforcement. Engineers can download the CISCO-SCAS-BB-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SCAS-BB-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 Service Control Engine (SCE) broadband platforms

Monitoring Examples

An operator would poll linkServiceUsageTable/linkServiceUsageEntry indexed by link and service to retrieve linkServiceUsageUpVolume, linkServiceUsageDownVolume, and linkServiceUsageNumSessions, tracking bandwidth consumption per service class on a broadband link. A sudden rise in linkServiceUpDroppedPackets or linkServiceDownDroppedPackets alongside linkServiceUsageConcurrentSessions nearing capacity would indicate the SCE is under-provisioned or a service is being throttled. linkServiceUsageActiveSubscribers gives a real-time view of how many subscribers are actively using a given service.

What Can Be Monitored

upstream/downstream traffic volume per service
concurrent sessions per link
active subscribers per service
session duration
dropped packets (upstream/downstream)
number of sessions per service

How to Use in IPNetwork Monitor

Example using linkServiceUsageUpVolume OID:

Select a Cisco Service Control Engine (SCE) broadband 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 linkServiceUsageUpVolume 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. The link service-counter upstream volume. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in KBytes), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
