Description: Manages Expand Networks AcceleratorOS WAN optimization appliance configuration and performance metrics.

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 EXPAND-ACCELERATOROS-MIB?

EXPAND-ACCELERATOROS-MIB is a vendor-specific SNMP module from Expand Networks, a WAN optimization/acceleration vendor later acquired by Riverbed, covering their AcceleratorOS-based WAN optimization appliances. Based on its stated purpose it exposes configuration and performance metrics tied to WAN traffic acceleration and optimization on these appliances. As a hardware/software status MIB it would be expected to surface appliance health indicators such as uptime, CPU/memory load, and compression or throughput statistics reflecting the optimization engine's operating state, though no concrete object names are available in the source data to confirm the exact structure. It likely depends on standard system MIBs (e.g., SNMPv2-MIB, IF-MIB) for base interface and system identity alongside its own acceleration-specific objects. It's typically deployed at branch-office or data-center WAN edges where Expand Networks appliances optimize and accelerate wide-area network traffic, and the EXPAND-ACCELERATOROS-MIB download would be sourced from Expand Networks (or its successor Riverbed) to monitor these appliances via SNMP.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXPAND-ACCELERATOROS-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

No sample objects were provided for this module, so specific table or scalar names can't be confirmed; based on its stated purpose, an admin would typically poll it for WAN link utilization, compression/optimization ratio, or optimized-versus-raw traffic counters to detect degraded acceleration performance or a link nearing capacity.

What Can Be Monitored

WAN link utilization
traffic compression/optimization ratio
appliance operating status
optimization performance metrics
