snmpCommunityTable for the new trap community string. The trap community
string can be part of the TrapGroup, ReadGroup, or ReadWriteGroup. If the
trap community string is used solely for sending traps (recommended), then it
should be made part of the TrapGroup.

You must add GroupName and RowStatus on the same set.

SNMP v3 USM Users

You can define up to 10 User-based Security Model (USM) users (USM users are referred to
as "v3 users"). Each v3 user can be associated with an authentication type (none, MD5, or
SHA-1) and a privacy type (none, DES, 3DES, or AES).
