• Authenticates all messages to verify they are from a valid source.
• Verifies the integrity of each message by making sure each packet has not been tampered with in-transit.
SNMPv3 also provides security models and security levels. A security model is an authentication strategy that is
set up for a user and the group in which the user resides. A security level is a permitted level of security within a
security model. A combination of a security model and security level will determine which security mechanism is
employed when handling an SNMP packet.
Before configuring SNMP, note the following:
• each user belongs to a group
• a group defines the access policy for a set of users
• an access policy defines what SNMP objects can be accessed for: reading, writing and creating notifications
• a group determines the list of notifications its users can receive
• a group also defines the security model and security level for its users

The current MIB files supported by RUGGEDCOM ROX II can be downloaded from the
https://www.siemens.com/ruggedcom .
NOTE
SNMP traps are not configurable in RUGGEDCOM ROX II.
The MIB files support the following SNMP traps:
Standard MIB Trap and Description
RFC 3418 SNMPv2-MIB authenticationFailure
An authenticationFailure trap signifies that the SNMP entity has received a protocol
message that is not properly authenticated. While all implementations of SNMP
entities MAY be capable of generating this trap, the snmpEnableAuthenTraps
object indicates whether this trap will be generated.
