DESCRIPTION
"The value of the community string field of an SNMPv1
message containing a Trap PDU which is forwarded by a
a proxy forwarder application using an SNMP version
other than SNMPv1. The value of this object SHOULD
contain the value of the community string field from

The OMNM application always adds snmpTrapAddress to every trap forwarded as a proxy,
(never adding
snmpTrapCommunity ). It does not keep track of the community string on the
traps received.
