Description: Manages Peribit Sequence Reducer WAN optimization device, reporting compression effectiveness, tunnel state, and throughput statistics.

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 PERIBIT-SR-MIB?

PERIBIT-SR-MIB is a Peribit Networks enterprise MIB for the Sequence Reducer family of WAN optimization appliances, which use data deduplication/compression to reduce WAN bandwidth usage. Although its sample objects were not enumerated in the source, such a MIB would typically expose objects covering compression ratio, tunnel/peer connection state, and throughput statistics between paired appliances. It would be used to monitor both the software status of the optimization tunnels (e.g., peer connectivity and compression effectiveness) and general appliance performance, revealing when a WAN link's effective throughput has dropped or a peer tunnel has gone down. It is a self-contained Peribit enterprise module that registers under the PERIBIT-GLOBAL-REG OID tree rather than extending an IETF standard. It is deployed on Peribit Sequence Reducer appliances positioned at each end of a WAN link to accelerate and monitor optimized traffic, making the PERIBIT-SR-MIB MIB the standard reference for tracking tunnel and compression status between paired appliances.

IPNetwork Monitor allows you to monitor SNMP objects defined in PERIBIT-SR-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

Peribit Sequence Reducer appliance
WAN optimization appliance

Monitoring Examples

Because no sample_objects were provided for this module, specifics cannot be grounded in real object names; a realistic scenario would involve polling a tunnel/peer status table to confirm a Sequence Reducer pair is connected, and compression/throughput counters to see the effective bandwidth savings on a WAN link. A drop in reported compression ratio or a tunnel status change to down would indicate a WAN optimization problem needing investigation. This description should be treated as inferred from the short description rather than grounded in specific MIB objects.

What Can Be Monitored

tunnel/peer connection status
compression ratio
WAN throughput statistics

How to Use in IPNetwork Monitor

Example using pnSrSysStatsBytesInAe OID:

Select a Peribit Sequence Reducer appliance, WAN optimization 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 pnSrSysStatsBytesInAe into the Find box to locate it in the OID tree, then select it and click OK. It reports the total number of bytes that entered the SR Assembly Engine since the system was started. 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.
