wfNhrpServerNegativeTTL
Module: Wellfleet-NHRP-MIB
OID (symbolic): Wellfleet-NHRP-MIB::wfNhrpServerNegativeTTL
OID (numeric): 1.3.6.1.4.1.18.3.5.3.23.1.1.25
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Time in seconds for negative caching of DNS records.
What is wfNhrpServerNegativeTTL?
Read-write time in seconds (1-65535, default 10) that a negative DNS cache entry (see wfNhrpServerNegativeCaching) remains valid before the server will retry the lookup. An admin shortens this to recover faster after a transient DNS outage.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.23.1.1.25 snmpwalk -v2c -c public <target> Wellfleet-NHRP-MIB::wfNhrpServerNegativeTTL
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.23.1.1.25.1 snmpget -v2c -c public <target> Wellfleet-NHRP-MIB::wfNhrpServerNegativeTTL.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.23.1.1.25.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> wfNhrpServerNegativeTTL.1
