Description: Ubiquiti EdgeSwitch DNS resolver MIB for configuring DNS name resolution settings and monitoring resolver status.

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 EdgeSwitch-DNS-RESOLVER-CONTROL-MIB?

The EdgeSwitch-DNS-RESOLVER-CONTROL-MIB is a private enterprise MIB module for Ubiquiti Networks' EdgeSwitch line of managed switches, built on the Broadcom-derived FastPath switch software stack. It exposes configuration and status objects for the switch's built-in DNS client/resolver, covering enabling or disabling name resolution, the configured DNS server addresses, and default domain name settings. Though mostly configuration-oriented, it lets an administrator confirm the operational status of the resolver service on the switch, effectively verifying that a piece of management-plane software critical to name-based configuration is functioning. It depends on the vendor's broader FastPath enterprise MIB tree and standard SNMPv2 conventions rather than any external standards body MIB. It is typically polled or configured by network management systems administering fleets of Ubiquiti EdgeSwitch access and aggregation switches in enterprise or ISP networks. Engineers can download the EdgeSwitch-DNS-RESOLVER-CONTROL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EdgeSwitch-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.

Monitoring Examples

An administrator would check a resolver-enable flag together with a table of configured DNS server IP addresses to confirm the switch can resolve hostnames used elsewhere, such as an NTP server or RADIUS server configured by name rather than IP. If the resolver is enabled but no configured DNS server responds, hostname-based configuration on the switch will silently fail, and this MIB is where that misconfiguration would first surface. No object names were extracted from the parsed source for this module, so specifics are inferred from FastPath's standard DNS client control conventions.
