As you know, Commvault’s alerts are supported with SNMPv1 and SNMPv3, but do you know why SNMPv2 is not supported?
One of our customers is using v2 and he is interesting to use this protocol…

SNMP V2 uses only primary authentication where as SNMP v3 uses both primary and secondary authentication(two level of password protection).
Since SNMP v3 is more secure and an industry standard commonly used method, we suggest to use SNMP v3 method to send or receive traps.
