Versions Supported

Extreme Networks devices support three versions of SNMP:

• Version 1 (SNMPv1) — This is the initial implementation of SNMP. Refer to RFC 1157 for a full description of functionality.
• Version 2 (SNMPv2c) — The second release of SNMP, described in RFC 1907, has additions and enhancements to data types, counter size, and protocol operations.
• Version 3 (SNMPv3) — This is the most recent version of SNMP, and includes significant enhancements to administration and security. The major difference between SNMPv3 and earlier versions is that v3 provides a User-Based Security Model (USM) to associate users with managed access to security information. In addition to better security and better access control, SNMPv3 also provides a higher degree of reliability for notifying management stations when critical events occur.

  SNMPv3 is fully described in RFC 2571, RFC 2572, RFC 2573, RFC 2574, and RFC 2575.
