Description: Manages DNS client resolver configuration and cache statistics on Bay Networks (Nortel) routers.

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 BayNetworks-DNS-MIB?

BayNetworks-DNS-MIB is a Bay Networks (later Nortel) enterprise MIB that manages DNS client resolver configuration and reports DNS cache statistics on Bay Networks/Nortel routers. It exposes configuration-oriented data, such as which DNS servers/resolvers the device is configured to use, along with runtime cache statistics reflecting DNS lookup activity. Its monitoring emphasis is on software/service status rather than physical hardware: confirming the router's configured name servers are correct and watching cache hit/miss behavior as an indicator of DNS resolution health for the device's own management and operational lookups. No module description text or object list was available for this module, so its exact objects cannot be confirmed beyond what the short description implies, but as a name-resolution MIB it would implicitly depend on standard DNS protocol semantics rather than another SNMP MIB. It is deployed on Bay Networks/Nortel routers where the device itself performs DNS lookups (e.g., for logging, NTP, or management hostnames) and operators want visibility into resolver configuration and cache behavior. Network engineers evaluating or troubleshooting this functionality can download the BayNetworks-DNS-MIB file directly to load it into their MIB browser.

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

Bay Networks/Nortel routers

Monitoring Examples

No specific object or table names were provided in the available data for this module, so a detailed polling example cannot be grounded in real object identifiers; in general terms, an operator would expect to check the device's configured DNS server addresses and DNS cache statistics (such as query counts or cache entries) to confirm the router can still resolve hostnames it depends on for its own operation.

What Can Be Monitored

configured DNS server addresses
DNS resolver cache statistics
