Simple Network Management Protocol (SNMP)

Protocol Overview

Network management stations use the Simple Network Management Protocol (SNMP) to retrieve or alter
management data from network elements. A datum of management information is called a managed
object; the value of a managed object can be static or variable. Network elements store managed objects in
a database called a Management Information Base (MIB).
MIBs are hierarchically structured and use object identifiers to address managed objects, but managed
objects also have a textual name called an object descriptor.
Note: On Dell Force10 routers, standard and private SNMP MIBs are supported, including all Get and a
limited number of Set operations (such as

Implementation Information

• FTOS 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.
• FTOS supports up to 16 trap receivers.
• The FTOS implementation of the sFlow MIB supports sFlow configuration via SNMP sets.
• SNMP traps for STP and MSTP state changes are based on BRIDGE MIB (RFC 1483) for STP and
IEEE 802.1 draft ruzin-mstp-mib-02 for MSTP.
• All objects in the LLDP-EXT-DOT1-DCBX-MIB and IEEE8021-PFC-MIB tables are read-only.
• In the LLDP-EXT-DOT1-DCBX-MIB, lldpXdot1dcbxRemoteData tables are not supported.

Configure Simple Network Management Protocol

Note: The configurations in this chapter use a UNIX environment with net-snmp version 5.4. This is only
one of many RFC-compliant SNMP utilities you can use to manage your Dell Force10 system using
SNMP. Also, these configurations use SNMP version 2c.
Configuring SNMP version 1 or version 2 requires only a single step:
1. Create a community. See
