What is rlMaxDnsClNCacheErrEntriesAfterReset?

This read-write INTEGER sets the future maximum size of the DNS client's negative (failed-lookup) cache, effective after the device's next reset. An admin raises this ahead of a reboot if many distinct hostnames are expected to fail resolution at once, such as during a DNS outage affecting several configured server names. For example, doubling this after-reset value ensures the negative cache doesn't overflow when several syslog and NTP hostnames simultaneously become unresolvable.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.29.18.4
snmpwalk -v2c -c public <target> CISCOSB-Tuning::rlMaxDnsClNCacheErrEntriesAfterReset

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.29.18.4.1
snmpget -v2c -c public <target> CISCOSB-Tuning::rlMaxDnsClNCacheErrEntriesAfterReset.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.6.1.101.29.18.4.1 i <value>
