7. Proxy to SNMPv1

The rfc1157Domain is deprecated in favor of snmpUDPDomain. The OBJECT-IDENTITY value rfc1157Domain was defined in the historical SNMPv2-TM-MIB module and is deprecated. All future transport mappings for SNMPv1 should be done using OBJECT-IDENTITY snmpUDPDomain instead.

The coexistence between SNMPv1, SNMPv2c, and SNMPv3 is described in [RFC2576].
