| dnsResConfigSbeltEntry OBJECT-TYPE An entry in the resolver's Sbelt table. Rows may be created or deleted at any time by the DNS resolver and by SNMP SET requests. Whether the values changed via SNMP are saved in stable storage across `reset' operations is implementation-specific. | 1.3.6.1.2.1.32.2.1.1.4.1 | not-accessible | current | |

| dnsResConfigResetTime OBJECT-TYPE If the resolver has a persistent state (e.g., a process) and supports a `reset' operation (e.g., can be told to re-read configuration files), this value will be the time elapsed since the last time the resolver was `reset.' For software that does not have persistence or does not support a `reset' operation, this value will be zero. | 1.3.6.1.2.1.32.2.1.1.6 | DnsTime | read-only | current |
| dnsResConfigReset OBJECT-TYPE Status/action object to reinitialize any persistant resolver state.

Query operations can return this state. disabled(2) means that the negative response cache is not being used. Query operations can return this state. Setting this variable to clear(3) deletes the entire contents of the resolver's negative response cache. The status will retain its previous value from before the clear operation (i.e., enabled(1) or disabled(2)).
