If a password file is used, and the host definition exists in the password file, then the configuration will be read from the password file. For backwards compatibility, the exdesc can contain the SNMP version, community string, and authentication, however that information will only be read if a password file is not found. If a password file has been configured then the interface will expect to get the configuration from the file.
When parsing the password file, if the host is found but the version is not specified then the following defaults will be:
-
If you configure User=x, then V3 is used.
-
If you configure CS=x or WCS=x, then V1 is used
Typically the version is specified in the password file along with the other configuration options. For backwards compatibility, if the password file is not being used, the version must be set in the exdesc, or the same default values will be used.
