Node type: NOTIFICATION-TYPE

Description: This notification indicates that a DNS secondary server cannot reach any of its configured masters to obtain a zone transfer. Once this situation is encountered generation of this notification will be suppressed until a complete zone transfer has completed as indicated by the ciscoNetRegMastersResp notification.

The identity of the secondary server is given by cnrNotifDnsServerIpAddress; the identity of the master servers is given by the cnrNotifDnsRemoteServersList; and the zone is given by cnrNotifZoneName.

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::ciscoNetRegMastersNotResp
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.120.2.0.17

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:

zoo11-linux.zoo [UDP: [192.168.30.111]:54655->[192.168.30.10]:162]:
