Description: Manages DNS resolver configuration including nameserver addresses and domain search lists on Dell DNOS 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 DNOS-DNS-RESOLVER-CONTROL-MIB?

DNOS-DNS-RESOLVER-CONTROL-MIB is a Dell enterprise MIB for Dell Networking OS (DNOS) switches that manages the device's DNS client/resolver configuration, such as configured nameserver addresses and domain search lists used when the switch itself needs to resolve hostnames. It exposes configuration-only data rather than performance counters, faults, or environmental readings. Its monitoring relevance is limited to configuration/software status verification: confirming which DNS servers and search domains a switch is configured to use, useful for diagnosing failures in features like NTP, syslog, or TACACS+ that depend on hostname resolution. No sample objects were provided in this batch, so specific object names are unavailable, but it would depend conceptually on standard DNS client MIB concepts and Dell's private enterprise MIB tree. It is deployed on Dell EMC Networking switches/routers running DNOS as part of general device configuration auditing. Engineers can download the DNOS-DNS-RESOLVER-CONTROL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DNOS-DNS-RESOLVER-CONTROL-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

Dell EMC Networking DNOS switches/routers

Monitoring Examples

No object or table names were provided in the source data for this MIB, so specific instances cannot be cited; based on its description, it would expose configuration objects for DNS nameserver addresses and domain search lists that an administrator polls to confirm the switch's resolver settings, which would explain a failure in any dependent feature (NTP, syslog, TACACS+) that relies on hostname resolution.

What Can Be Monitored

configured DNS nameserver addresses
DNS domain search list
DNS resolver configuration status
