User's Manual

The v3 protocol security level. Switches on/off Authentication (Auth) and the SNMP data encryption
(Priv).
• Authentication
List box {MD5_legacy; SHA1_legacy; SHA224; SHA256; SHA384; SHA512}, default = "SHA256"
Authentication algorithm. Legacy algorithms are not recommended to use, they are available for
compatibility reasons only.
• Authentication passphrase
String {8..128 char}, default = <empty>
Passphrase used for authentication with SNMP server.
• Encryption
List box {DES_legacy; AES128; AES192; AES256}, default = "AES128"
Encryption algorithm.
• Encryption passphrase
String {8..128 char}
Passphrase used for data encryption when communicating with SNMP server.
• Engine ID mode
List box {Default; User defined}, default = "Default"
Engine Id serves for unique identification of the SNMP instance (i.e. the RipEX unit) according to
RFC3411. When the "Default" Engine ID mode is selected the MAC address of the Eth1 interface is
used for the unique part of the Engine Id (the whole Engine ID example: 800083130302a92006ef).
• Engine ID
String {1..27 char}
When "User defined" Engine ID mode is selected the differentiated part of the Engine ID can be
entered as ASCII characters or generated (e.g. U3qPrisWoDYbBVNsAWluZYGL3M5). This string
is converted into HEX number (i.e. 55 33 71 50 72 69 73 57 6f 44 59 62 42 56 4e 73 41 57 6c 75 5a
59 47 4c 33 4d 35). The whole Engine ID for mentioned example:
800083130455337150726973576f44596242564e7341576c755a59474c334d35.
Notification
Notification is used for asynchronous notification from a RipEX unit into the SNMP server.
• Notification mode
List box {Off; Trap; Inform}, default = "Off"
Mode of notification; Inform is not supported by SNMPv1
• Notification version
List box {v1; v2c; v3}, default = "v2c"
Notification packets version.
• Inform repeats
Number {0 – 10}, default = 3
Number of repeats used when Inform acknowledge was not received.
• Inform timeout [s]
Number {1 – 20}, default 10
Inform acknowledge timeout.
