usrDnsNCacheErrCode
Module: USR-DNS-MIB
OID (symbolic): USR-DNS-MIB::usrDnsNCacheErrCode
OID (numeric): 1.3.6.1.4.1.429.4.17.25.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The authoritative error that has been cached: nonexistantName(1) indicates an authoritative name error (RCODE = 3). noData(2) indicates an authoritative response with no error (RCODE = 0) and no relevant data. other(3) indicates some other cached authoritative error. At present, no such errors are known to exist.
What is usrDnsNCacheErrCode?
Reports the specific authoritative error cached: nonexistantName (authoritative name error, RCODE 3), noData (authoritative response with no error but no relevant data), or other. An admin uses this to distinguish a true NXDOMAIN from a valid-but-empty answer when a lookup keeps failing.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.17.25.1.7 snmpwalk -v2c -c public <target> USR-DNS-MIB::usrDnsNCacheErrCode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.17.25.1.7.1 snmpget -v2c -c public <target> USR-DNS-MIB::usrDnsNCacheErrCode.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> usrDnsNCacheErrCode.1
