<WorkspaceDirectory>\DataFiles\xio.SNMP.UserDefinitions.dat The SNMP Module provides the transfer of encrypted data If SNMP v3 is used, the transferred data is encrypted between the device and the NETx BMS Core Server. The defined user have to be added to the SNMP device definition file, to allow the successful decryption of data from the device.
The structure of the SNMP user definition file is as follows: 'SNMP user configuration file
'Authentication name; Authentication Protocol; Authentication key; Privacy Protocol; Privacy password user;NONE;NoAuthenticationKey;NONE;Noprivacykey; myuser;MD5;mypassword;DES;myotherpassword; theuser;SHA1;AuthenticationKey;AES;PrivacyKey;
Each line – except comment lines that start with ' – defines a single SNMP user definition.
...
To pariticapte in the encryted communication, an SNMP user has to be defined. The user definition specifies the used cryptographic algorithms and secrets.
