Description: Monitors transaction processor traffic statistics and flow counters on Cisco SCE Service Control Engine devices.

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-SERVICE-CONTROL-TP-STATS-MIB?

CISCO-SERVICE-CONTROL-TP-STATS-MIB provides statistics for the traffic processor(s) inside a Cisco Service Control Engine (SCE), a network element that inspects and polices subscriber traffic against configured policies. It belongs to the deep-packet-inspection/traffic-management technology area and exposes performance-counter data: total and active flow/packet counts, protocol-specific (TCP/UDP) active flow counts, blocked packet/flow counts, and discard counters for bandwidth and WRED policy enforcement. This data is explicitly noted to reflect the general load on the system, making it a direct software/performance-load monitoring tool for the SCE's packet-processing engine rather than a hardware-environmental MIB. It is a self-contained Cisco SCE data module with no strong dependency on other MIBs beyond general SNMP framework conventions. It is typically deployed on Cisco SCE platforms used by service providers for subscriber-aware traffic management and policy enforcement, where CISCO-SERVICE-CONTROL-TP-STATS-MIB SNMP monitoring gives operators direct visibility into traffic-processor load.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SERVICE-CONTROL-TP-STATS-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.

Monitoring Examples

An operator would poll cscTpTable entries for cscTpTotalHandledPackets/Flows and cscTpActiveFlows (with cscTpTcpActiveFlows and cscTpUdpActiveFlows broken out) to gauge current traffic load on each traffic processor. A sudden rise in cscTpTotalBlockedFlows, cscTpTotalBandwidthDiscardedPackets, or cscTpTotalWredDiscardedPackets alongside high cscTpTotalFragments would indicate the processor is under congestion and actively shedding traffic per configured policy, a signal to investigate capacity or policy tuning.

What Can Be Monitored

total handled packets/flows
active TCP/UDP flow counts
blocked packets/flows
bandwidth/WRED discarded packets
fragment counts

How to Use in IPNetwork Monitor

Example using cscTpTotalHandledPackets OID:

Select a Cisco Service Control Engine (SCE) 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 cscTpTotalHandledPackets 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 indicates the number of packets handled by this traffic processor since last restart. 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 Counter64-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 packets), 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.
