Description: Provides SNMP management objects for monitoring packet filter rule counters and traffic 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 PacketFilter-MIB?
PacketFilter-MIB is a generic-sounding SNMP module intended to provide management objects for monitoring packet filter rules and their associated traffic counters/statistics, though the specific vendor origin is not clear from the available module description alone. It is expected to expose configuration-style data about defined filter rules along with performance/traffic counters showing how much traffic each rule has matched, permitted, or denied. As a security/traffic-filtering MIB it is more relevant to software-level packet-processing status than to physical hardware health - it would be used to confirm packet filter rules are active and to monitor how much traffic is being blocked or passed, which can reveal firewall/ACL misconfiguration or attack traffic. No sample objects or module description text were available to determine specific dependencies, so it should be cross-checked against the actual MIB source before deployment. It would typically be deployed on a firewall, router, or security appliance that implements packet-filtering/ACL functionality. Engineers can download the PacketFilter-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in PacketFilter-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
- Microsoft Internet Information Server/Proxy Server, Windows NT era (packet filter rule statistics)
Monitoring Examples
No sample objects were provided for this MIB, so a concrete polling scenario referencing real object names cannot be given; based on the description alone, an operator would likely poll per-rule match/permit/deny counters to detect unexpectedly high deny rates (possible attack or misconfiguration) or zero-hit rules (stale/unused ACL entries). This should be verified against the actual MIB definition before building monitoring around it.
What Can Be Monitored
- packet filter rule counters
- matched/permitted traffic
- denied/dropped traffic
- filter rule status
