wfNhrpServerNegativeCaching
Module: Wellfleet-NHRP-MIB
OID (symbolic): Wellfleet-NHRP-MIB::wfNhrpServerNegativeCaching
OID (numeric): 1.3.6.1.4.1.18.3.5.3.23.1.1.24
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enable/disable negative caching of DNS records.
What is wfNhrpServerNegativeCaching?
Read-write enable(1)/disable(2) switch (default enable) for caching negative (failed) DNS lookup results so the server doesn't repeatedly re-query DNS for a name that recently failed to resolve. An admin disables this if stale negative results are causing resolutions to fail even after the DNS record becomes available.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.23.1.1.24 snmpwalk -v2c -c public <target> Wellfleet-NHRP-MIB::wfNhrpServerNegativeCaching
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.23.1.1.24.1 snmpget -v2c -c public <target> Wellfleet-NHRP-MIB::wfNhrpServerNegativeCaching.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.23.1.1.24.1 i <value>
