Description: Huawei DHCP snooping MIB providing objects to configure and monitor DHCP snooping security, binding tables, and untrusted port filtering.

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 HUAWEI-DHCP-SNOOPING-MIB?

HUAWEI-DHCP-SNOOPING-MIB is a Huawei-proprietary security MIB implemented on Huawei switches to configure and monitor the DHCP Snooping feature, which inspects DHCP traffic to prevent rogue DHCP servers and IP/MAC spoofing on access ports. Its data spans configuration objects (enabling snooping per VLAN or port, marking ports as trusted/untrusted) and state objects such as the DHCP snooping binding table that records learned IP-to-MAC-to-port associations. As a security/access-control feature it is monitored primarily for software/configuration status: whether snooping is enabled on the expected VLANs, how many bindings are currently learned, and whether untrusted-port filtering is actively blocking unauthorized DHCP server responses. It builds on the standard DHCP protocol (RFC 2131) and VLAN tagging (IEEE 802.1Q) concepts, since bindings and enforcement are scoped per VLAN. It is typically deployed on Huawei enterprise or campus access switches at the network edge to protect subscriber or client ports from DHCP-based attacks, and administrators typically download the HUAWEI-DHCP-SNOOPING-MIB file directly from Huawei to compile into their monitoring system.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-DHCP-SNOOPING-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

  • Huawei enterprise/campus access switches

Monitoring Examples

An administrator would poll the VLAN-scoped snooping-enabled object and the DHCP snooping binding table to confirm which ports have learned legitimate client IP/MAC bindings, and would check the untrusted-port filtering counters to see how many rogue DHCP packets were dropped. The supplied module description text actually describes the 12-bit VLAN ID field format rather than binding-table object names, so specific binding-table object names cannot be confirmed from the given data. A sudden spike in dropped/filtered DHCP packets on an untrusted port would indicate an attempted rogue DHCP server or spoofing attack on that segment.

What Can Be Monitored

  • DHCP snooping enable/disable status per VLAN or port
  • DHCP binding table entries (IP/MAC/port)
  • trusted vs untrusted port configuration
  • filtered/dropped rogue DHCP packet counts
