SNMP and MIB Support

The Express 10/100 Switch contains a built-in SNMP agent running on the SNMP processor board. This allows each Express 10/100 Switch to be managed from a centralized management station via any SNMP-compliant NMS.

The SNMP agent software complies with the following standards:

•RFC 1155, The Structure of Management Information (SMI) for TCP/IP Based Internets, 5/90.

•RFC 1556, Management Information Base (MIB) for Network Managers of TCP/IP Based Internets, 5/90.

•RFC 1557, The Simple Network Management Protocol (SNMP), 5/90.

•RFC 1213, The Management Information Base II (MIB II), 3/91.

•RFC 1643, Definitions of Managed Objects for the Ethernet-like Interface Types.

•RFC 1573, Evolution of the Interfaces Group of MIB-II, 1/94.

•RFC 1493, Definitions of Managed Objects for Bridges, 7/93.

•RFC 793, Transmission Control Protocol.

•RFC 854, Telnet Protocol Specification.

•RFC 1055, Nonstandard for transmission of IP datagrams over serial lines: SLIP, 1/88.

The SNMP agent uses UDP/IP (RFC 768, RFC 950, RFC 1071 and RFC 791) as OSI layers 3 and 4 protocols, and ICMP (RFC 792) and ARP (RFC 826) to complete the UDP/IP protocol suite.

The UDP/IP stack implementation is conformant to:

•RFC 1122, Requirements for Internet hosts, communication layers.

•RFC 1123, Requirements for Internet hosts, application and support.

You can manage the Express 10/100 Switch with any SNMP Manager that conforms to the above standards.

The Express 10/100 Switch implements an Intel Enterprise MIB. Download SWCH2MIB.EXE from the Intel Customer Support World Wide Web site (http://support.intel.com) or Intel’s FTP site (see inside back cover).
