NMS-DHCP-SNOOPING-MIB

Description: Monitors NMS Communications DHCP snooping binding tables and untrusted port enforcement for LAN security.

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.

NMS-DHCP-SNOOPING-MIB is a vendor MIB from NMS Communications that governs DHCP snooping, a Layer 2 security feature used to prevent rogue DHCP servers and IP/MAC spoofing on access switches. It exposes configuration-style data, principally a global enable/disable status flag for the snooping feature on the device. Rather than hardware health, its monitoring value is in software/feature-state status: an operator polls this object to confirm the security feature is actually active (rather than silently disabled) as part of compliance or security posture checks. It is a self-contained vendor MIB with no explicit dependency noted on other standard MIBs. It is typically deployed on NMS Communications-branded access or aggregation switches in enterprise or carrier LAN environments where DHCP spoofing protection is required. Engineers can download the NMS-DHCP-SNOOPING-MIB file directly to load it into their MIB browser.

The single scalar status object (0-disable, 1-enable) documented in the module description would typically be polled periodically to verify DHCP snooping remains enabled; a value flipping to 0 unexpectedly would indicate the security control was disabled, either by misconfiguration or a malicious change, and should trigger an alert. No per-binding or per-port table objects are disclosed in the available data, so detailed snooping-binding monitoring cannot be described from this source alone.

Monitors DHCP bindings and snooping activity with IP-MAC address association tracking.
