SNMPv3 primarily added security and encryption to SNMP. Security has been the biggest weakness of SNMP since the beginning. Authentication in SNMP Versions 1 and 2 amounts to nothing more than a password (community string) sent in clear text between a manager and agent.

Each SNMPv3 message contains security parameters which are encoded as an octet string. The meaning of these security parameters depends on the security model being used. SNMPv3 provides important security features:

• Confidentiality - Encryption of packets to prevent snooping by an unauthorized source.
• Integrity - Message integrity to ensure that a packet has not been tampered with in transit.
• Authentication - to verify that the message is from a valid source.

To configure your Communications Manager for SNMPv3 traps follow the procedures listed in 'Configuring SNMP traps' and populate the V3 sections as described below:

CM SNMP Traps

 Once a destination has been configured for SNMPv3 trap, enter the matching information in AlarmTraq under SNMP v3 Users.
