SNMP Configuration
This chapter describes the Simple Network Management Protocol (SNMP) set of commands and
how to use them.
5.1 SNMP CONFIGURATION SUMMARY
SNMP is an application-layer protocol that facilitates the exchange of management information
between network devices. SNMP enables network administrators to manage network performance,
find and solve network problems, and plan for network growth.
Matrix E1 Series 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 (SNMPv2) — 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. SNMPv3 is fully described in RFC 2571, RFC
2572, RFC 2573, RFC 2574, and RFC 2575.
5.1.1 SNMPv1 and SNMPv2
The components of SNMPv1 and SNMPv2 network management fall into three categories:
• Managed devices (such as a switch).
• SNMP agents and MIBs, including SNMP traps, community strings, and Remote Monitoring
(RMON) MIBs, which run on managed devices.
• SNMP network management applications, such as Enterasys Networks’ NetSight Atlas, which
communicate with agents to get statistics and alerts from the managed devices.
