Users Guide

MIBs are hierarchically structured and use object identifiers to address managed objects, but managed
objects also have a textual name called an object descriptor.
Implementation Information
The following describes SNMP implementation information.
• Dell Networking OS supports SNMP version 1 as defined by RFC 1155, 1157, and 1212, SNMP version 2c
as defined by RFC 1901, and SNMP version 3 as defined by RFC 2571.
• Dell Networking OS supports up to 16 trap receivers.
• Dell Networking OS implementation of the sFlow MIB supports sFlow configuration via SNMP sets.
• SNMP traps for the spanning tree protocol (STP) and multiple spanning tree protocol (MSTP) state
changes are based on BRIDGE MIB (RFC 1483) for STP and IEEE 802.1 draft ruzin-mstp-mib-02 for
MSTP.
Configuration Task List for SNMP
Configuring SNMP version 1 or version 2 requires a single step.
NOTE: The configurations in this chapter use a UNIX environment with net-snmp version 5.4. This
environment is only one of many RFC-compliant SNMP utilities you can use to manage your Dell
Networking system using SNMP. Also, these configurations use SNMP version 2c.
• Creating a Community
Configuring SNMP version 3 requires configuring SNMP users in one of three methods. Refer to
Setting Up User-Based Security (SNMPv3).
