Description: Monitors WAN optimization appliance settings, compression ratios, deduplication statistics, and accelerated application performance.

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 WAN-OPT-MIB?

WAN-OPT-MIB is a vendor-specific MIB for a WAN optimization/acceleration appliance (its object naming, e.g. cdx6500PSTLANConnectionGroup, points to a "CDX6500"-class optimization platform) that improves application performance over wide-area links via compression, deduplication, and protocol acceleration. It exposes configuration and statistics objects for LAN-side connection groups, along with compression-ratio, deduplication, and accelerated-throughput counters for optimized WAN traffic flows. From a monitoring perspective it lets an operator track how effectively the appliance is optimizing traffic — compression/dedup ratios achieved and connection counts per group — which indirectly reflects both the appliance's software processing health and the WAN link's traffic load. It likely complements standard interface/host MIBs (IF-MIB, HOST-RESOURCES-MIB) for baseline device health while adding optimization-specific statistics unique to WAN acceleration appliances. It is deployed in enterprise branch/data-center pairs at each end of a WAN optimization solution to accelerate application traffic (e.g., file transfer, backup, or replication traffic) across a wide-area network. Engineers can download the WAN-OPT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WAN-OPT-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

WAN optimization/acceleration appliance (CDX6500-class)

Monitoring Examples

The cdx6500PSTLANConnectionGroup object grouping suggests the appliance tracks LAN-side connection groups on its interface, from which an admin would monitor active connection counts and their associated optimization statistics. A realistic scenario would have an operator polling this connection-group data to confirm that a given branch's traffic is actively being optimized and to spot a drop in the number of accelerated connections, which could indicate a WAN link outage or a failure in the optimization tunnel between appliance pairs. Because only one object name was supplied, more granular compression/dedup counter names cannot be confirmed beyond what the short description implies.

What Can Be Monitored
