Description: Huawei DNS MIB providing objects for configuring DNS client settings, server addresses, domain search lists, and name resolution 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 HUAWEI-DNS-MIB?

HUAWEI-DNS-MIB is a Huawei proprietary MIB reporting the device's dynamic DNS host cache, for both IPv4 and IPv6 resolution entries. Its dynamic-hosts tables record each cached domain name's resolved IP (or IPv6) address, TTL, and any alias, maintained separately for IPv4 and IPv6 lookups. As a software-status MIB it lets an administrator inspect the device's current DNS cache contents and TTLs, useful when diagnosing a stale-DNS-entry-related connectivity problem. It is deployed on Huawei routers/switches performing DNS resolution for local services. Engineers can download the HUAWEI-DNS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-DNS-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/switches (DNS resolution)

Monitoring Examples

An administrator checks hwDnsTtl for a cached entry showing an outdated IP address, confirming whether the cache simply hasn't expired yet or whether a resolution problem is preventing the refresh.

What Can Be Monitored

cached DNS host entries and TTLs (IPv4/IPv6)
