Description: Manages DNS client configuration including server addresses, domain lists, and resolution statistics on H3C devices.
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 HH3C-DNS-MIB?
HH3C-DNS-MIB is an H3C (Huawei-3Com/New H3C) enterprise MIB that manages the DNS client resolver configuration on H3C routers and switches. It exposes configuration-type data — configured DNS server addresses and domain search lists — alongside operational resolution statistics rather than physical sensor data. Its monitoring value is primarily in software/service status: it lets an operator confirm which name servers a device is actually configured to use and track whether DNS resolution attempts from the device are succeeding or failing, useful in diagnosing management or logging features on the device that depend on hostname lookups. It stands largely on its own as a vendor extension rather than depending on the standard DNS-related IETF MIBs. It is typically deployed on H3C enterprise switches and routers where SNMP-based centralized auditing of DNS settings is required. Engineers can download the HH3C-DNS-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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
- H3C (Huawei-3Com) routers and switches
Monitoring Examples
An operator would poll the configured DNS server address list and domain list objects to verify a device is pointed at the correct resolvers after a network change, and check resolution statistics counters for a spike in failed lookups that would indicate a DNS server outage is affecting the device's own hostname-based features (like NTP or syslog-by-name). No concrete object names were available for this module, so specific table/object names cannot be quoted, but they would follow the typical hh3cDns*Table/Entry naming convention used across other HH3C MIBs.
What Can Be Monitored
- configured DNS server addresses
- domain search list
- DNS resolution success/failure statistics
