/*
* There currently exists the following SNMP versions.
* * (Note that only SNMPv1 is in widespread usage, and this code supports
* * only SNMPv1, SNMPv2c, and SNMPv3.
* *
* * SNMPv1 - (full) the original version, defined by RFC 1157
* * SNMPsec - (historic) the first attempt to add strong security
* * to SNMPv1, defined by RFCs 1351, 1352, and 1353.
* * SNMPv2p - (historic) party-based SNMP, which was another
* * attempt to add strong security to SNMP, defined
* * by RFCs 1441, 1445, 1446, 1448, and 1449.
* * SNMPv2c - (experimental) community string-based SNMPv2,
* * which was an attempt to combine the protocol
* * operations of SNMPv2 with the security of
* * SNMPv1, defined by RFCs 1901, 1905, and 1906.
* * SNMPv2u - (experimental) user-based SNMPv2, which provided
* * security based on user names and protocol
* * operations of SNMPv2, defined by RFCs 1905,
* * 1909, and 1910.
* * SNMPv2* (or SNMPv2star) - (experimental) an attempt to add the
* * best features of SNMPv2p and SNMPv2u, defined
* * by unpublished documents found at WEB site
* * owned by SNMP Research (a leading SNMP vendor)
* * SNMPv3 - the current attempt by the IETF working group to merge
* * the SNMPv2u and SNMPv2* proposals into a more widly
* * accepted SNMPv3. It is defined by not yet published
* * documents of the IETF SNMPv3 WG.
* *
* * SNMPv1, SNMPv2c, SNMPv2u, and SNMPv3 messages have a common
* * form, which is an ASN.1 sequence containing a message version
* * field, followed by version dependent fields.
* * SNMPsec, SNMPv2p, and SNMPv2* messages have a common form,
* * which is a tagged ASN.1 context specific sequence containing
* * message dependent fields.
* *
* * In the #defines for the message versions below, the value
* * for SNMPv1, SNMPv2c, SNMPv2u, and SNMPv3 messages is the
* * value of the message version field. Since SNMPsec, SNMPv2p,
* * and SNMPv2* messages do not have a message version field,
* * the value in the defines for them is choosen to be a large
* * arbitrary number.
* *
* * Note that many of the version ID's are defined below purely for
* * documentational purposes. At this point the only protocol planned
* * for future implementations is SNMP3, as the other v2 protocols will
* * not be supported by the IETF (ie, v2u, v2sec, v2star) or used by
* * the snmp community at large (at the time of this writing).
