Changes in Authentication protocol, Authentication passphrase, Privacy protocol or Privacy passphrase, made without changing the Security name, will take effect only after the cache on a server/proxy is manually cleared (by using -R snmp_cache_reload) or the server/proxy is restarted. In cases, where Security name is also changed, all parameters will be updated immediately.
