Description: MIB for the Cisco ME1200 Metro Ethernet switch covering DNS proxy and resolver configuration objects.
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 ME1200-DNS-MIB?
ME1200-DNS-MIB is a Cisco private MIB providing DNS proxy and resolver configuration for the Cisco ME 1200 Metro Ethernet Access Switch, a carrier Ethernet demarcation device. It exposes global DNS configuration objects — server-selection setting, a statically configured DNS server address and VLAN ID, and DNS proxy admin state — alongside a status object reporting the DNS server's actual resolved IP address. For hardware/software status monitoring this MIB is a software/configuration health check: it lets an administrator confirm the switch's DNS proxy feature is administratively enabled and, more importantly, verify via the status table whether the switch is actually using the expected DNS server address, revealing a stale or unreachable DNS configuration that could impair other management functions relying on name resolution. It is described as a private version of the general DNS MIB concept, implying it parallels community DNS-server MIB conventions rather than depending on another vendor MIB directly. It is deployed on Cisco ME 1200 series switches in carrier/metro Ethernet access network deployments. Engineers can download the ME1200-DNS-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ME1200-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
- Cisco ME 1200 Metro Ethernet Access Switch
Monitoring Examples
An administrator would check me1200DnsGlobalsProxyAdminState to confirm DNS proxy is enabled, then compare me1200DnsGlobalsServerStaticAddress (and me1200DnsGlobalsServerStaticVlanId) against me1200DnsServerStatusIpAddress to verify the switch is actually resolving through the intended DNS server on the correct VLAN. If me1200DnsGlobalsServerSetting indicates static configuration but me1200DnsServerStatusIpAddress shows a different or unreachable address, that mismatch would explain DNS-dependent management features failing on the switch.
What Can Be Monitored
- DNS proxy admin state
- static DNS server address and VLAN
- actual resolved DNS server status
- DNS server selection mode
