usrDnsNCacheErrStatus
Module: USR-DNS-MIB
OID (symbolic): USR-DNS-MIB::usrDnsNCacheErrStatus
OID (numeric): 1.3.6.1.4.1.429.4.17.25.1.8
Node type: OBJECT-TYPE
Type: RowStatus
Access: read-write
Description: Status column for the resolver negative response cache table. Since only the agent (DNS resolver) creates rows in this table, the only values that a manager may write to this variable are active(1) and destroy(6).
What is usrDnsNCacheErrStatus?
Controls the row status of this negative-cache entry; since only the resolver creates rows, a manager may only set this to active(1) or destroy(6). An admin uses destroy to manually clear a stale negative-cache entry so the name gets re-queried.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.17.25.1.8 snmpwalk -v2c -c public <target> USR-DNS-MIB::usrDnsNCacheErrStatus
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.17.25.1.8.1 snmpget -v2c -c public <target> USR-DNS-MIB::usrDnsNCacheErrStatus.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.429.4.17.25.1.8.1 s <value>
