Node type: NOTIFICATION-TYPE
Description: This notification indicates that a DNS recursive resolver was able to reach at least one of its configured forwarders and indicates start of normal operation. This notification is generated the first time normal operation is established after a DNS recursive resolver was not able to reach any of its configured forwarders.

Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CISCO-NETWORK-REGISTRAR-MIB::ciscoNetRegDnsForwardersResp snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.120.2.0.21
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
