This memo is informational. It specifies an approach to add floating-point types to versions 1 and 2 of the SNMP SMI[1][2][3][4][5][6], and versions 1 and 2 of the SNMP protocol[7][8][9] without changes. Thus, this addition requires no modifications to existing SNMP MIB compilers, and no changes to existing SNMP protocol engines used in SNMP agents and SNMP management applications. This memo does not specify a standard for the Internet community.
