*************THIS OBJECT IS DEPRECATED **********
This object is used to indicate what version of
SNMP should be used to send the trap to this
destination. When the value of this object is
'snmpv1', the trap will be sent to this destination
as a Trap-PDU using an SNMPv1 message wrapper, as
specified in RFC 1157. When the value of this
object is 'snmpv2c', the trap will be sent to this
destination as a SNMPv2-Trap-PDU using the
Community-based SNMPv2 framework as specified in
RFC 1901.
An agent should reject an attempt to set an instance
of this object to a value representing a version of
the SNMP framework that is not supported by that
agent.
