30 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 set vlan and copy cmd). 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 page 517. Simple Network Management Protocol (SNMP) | 515
