Description: Manages Cisco WAN optimization settings including compression and deduplication on WAAS appliances.

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-WAN-OPTIMIZATION-MIB?

CISCO-WAN-OPTIMIZATION-MIB manages and monitors Cisco's WAN optimization systems, such as WAAS appliances, that reduce WAN traffic and improve application response time through techniques like TCP flow optimization, compression, and deduplication, operating as peer-based systems at both ends of a WAN link. It exposes general system health objects such as active peer counts and CPU throttling thresholds, alongside detailed TCP Flow Optimization (TFO) statistics covering total, active, and maximum optimized connections, broken down by connection type such as TCP-plus, TCP-only, and application-data. This MIB is heavily monitoring-oriented for both software and hardware status: CPU throttle high/low thresholds and throttle period reveal when the appliance is CPU-constrained and throttling optimization to protect itself, while active peers versus maximum active peers shows whether the device is near its peer-scaling limit. It functions as a peer-based system that depends on matching WAAS optimization peers at the other end of each WAN link to be effective. It is deployed on Cisco WAAS (Wide Area Application Services) appliances or WAN-optimization-capable routers at branch and data-center WAN edges. Engineers can download the CISCO-WAN-OPTIMIZATION-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-OPTIMIZATION-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 WAAS (Wide Area Application Services) appliance
  • Cisco WAN-optimization-capable router

Monitoring Examples

An administrator would poll cwoGeneralActivePeers against cwoGeneralMaxActivePeers to check whether a WAAS device is approaching its peering capacity, and cwoGeneralCpuThrottleHigh/cwoGeneralCpuThrottleLow to see if the appliance has begun throttling new optimized connections due to CPU load. cwoTfoStatsActiveOptConn versus cwoTfoStatsMaxActiveConn shows current TFO connection utilization, while a drop in cwoTfoStatsActiveOptTCPPlusConn relative to cwoTfoStatsActiveOptTCPOnlyConn could indicate optimization peers are falling back to basic TCP-only mode rather than full optimization. cwoTfoStatsTotalOptConn provides a cumulative count useful for capacity trending over time.

What Can Be Monitored

  • active vs max optimization peers
  • CPU throttle thresholds and period
  • total/active optimized connections
  • optimized connections by type (TCP-plus/TCP-only/app-data)

How to Use in IPNetwork Monitor

Example using cwoTfoStatsTotalOptConn OID:

Select a Cisco WAAS (Wide Area Application Services) appliance 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 cwoTfoStatsTotalOptConn into the Find box to locate it in the OID tree, then select it and click OK. This object contains total number of TCP connections optimized since TFO was started or its statistics were last reset. 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, 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.
