Description: Configures DNS client settings including server addresses on D-Link switches.

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 DLINKSW-DNS-MIB?

DLINKSW-DNS-MIB is a D-Link switch MIB for configuring the device's DNS client, primarily the configured DNS server address(es) used for name resolution by the switch's own management functions, such as resolving a syslog or NTP server hostname. It would expose the configured primary/secondary DNS server addresses and possibly domain-name settings, though no sample objects were extracted for this module. Its relevance to monitoring is confirming the switch can actually resolve hostnames for other management features that depend on DNS, since a misconfigured or unreachable DNS server would silently break hostname-based configuration elsewhere. It has no stated dependency beyond the general DNS protocol itself. It is deployed on any D-Link switch where management features reference servers by hostname rather than IP address, making DLINKSW-DNS-MIB SNMP monitoring useful for confirming the configured resolver is reachable.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINKSW-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

D-Link managed switch

Monitoring Examples

No object names were provided in sample_objects for this MIB, so a concrete polling scenario with real identifiers cannot be given honestly. Conceptually, an administrator would check the configured DNS server address to confirm it matches the intended resolver, particularly after diagnosing a failure in a hostname-dependent feature like NTP or syslog, but the exact object/table names are not confirmed here.
