Description: Huawei Ethernet ARP MIB providing ARP table management, ARP aging configuration, and ARP entry statistics for Ethernet interfaces.

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-ETHARP-MIB?

HUAWEI-ETHARP-MIB is a Huawei MIB module for managing Ethernet ARP (Address Resolution Protocol) behavior on Huawei routers and switches, covering features like ARP speed-limiting and ARP entry limits. It exposes configuration objects for ARP rate-limiting and maximum-entry thresholds along with objects for monitoring current ARP table statistics and aging behavior. Its monitoring value lies in tracking network-layer/software state: administrators can watch ARP entry counts and rate-limit hit counters to detect ARP flooding, spoofing attacks, or misbehaving hosts on a LAN segment. It extends the standard ARP concepts found in the IETF IP-MIB/ARP table but adds Huawei-specific protection and limiting features. It is deployed on Huawei access and aggregation switches/routers in campus and metro networks to protect the control plane from ARP-based abuse. Engineers can download the HUAWEI-ETHARP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-ETHARP-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 routers
  • Huawei switches

Monitoring Examples

Under the top-level hwEthernetARPObjects branch, an administrator would poll ARP limit and speed-limit configuration objects to confirm thresholds are set appropriately for a given interface or VLAN, and would monitor current ARP entry counts against those limits. A sudden spike in ARP entries approaching the configured limit, or a rising rate-limit-drop counter, would indicate an ARP flood or scanning activity on that segment. Sustained rate-limit triggering on an access port often points to a compromised or misbehaving host.

What Can Be Monitored

  • ARP table entry count
  • ARP rate-limit threshold and hits
  • ARP entry limit configuration
  • ARP aging behavior
