6.4Diagnostics Using SNMP

With SNMP (Simple Network Management Protocol), a network management station can configure and monitor SNMP-compliant nodes such as the ELS. To make this possible, a management agent is installed in the DTE with which the management station exchanges data using SNMP Get and Set requests. The ELS supports SNMP V1.

The data that can be managed are in a database on the DTE (ELS) known as the MIB (Management Information Base) that can be accessed by the management station (or the applet of the ELS Web-Based Management) using the agent.

There are standardized MIBs defined in RFCs and private MIBs. Private MIBs are based on RFC 1213 and contain product-specific expansions not included in standard MIBs.

The ELS with network management supports MIB II (RFC 1213).

ELS private MIB

The private MIB of the ELS is on the supplied CD.

The private MIB file can also be downloaded from an ELS directly with a Web browser at http://<IP address of the ELS>/snELS.mib.

Please note the capitalization of snELS.mib!

The description of the MIB objects of the private MIB is included in the MIB and can be read directly with a MIB compiler (for example the network management station) or with a text editor.

The read-only community string (SNMP password for read access) is set to public, the read-write community string (SNMP password for read and write access) is set to private.
