rlMaxDnsClNCacheErrEntriesAfterReset
Module: CISCOSB-Tuning
OID (symbolic): CISCOSB-Tuning::rlMaxDnsClNCacheErrEntriesAfterReset
OID (numeric): 1.3.6.1.4.1.9.6.1.101.29.18.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The future (after reset) maximal number of DNS client negative cache entries.
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.
