bOpen the corresponding table. If the table is empty, then empty columns will be displayed.

cClick on Edit. It is now possible to display the values for every single column in the table.

dEnter the index of the table and the value for the column to be subsequently placed, and click on Set at the right-hand side of the latter column.

A new column with the new index and the value for another column should now appear.

It is also possible to enter values for all columns of the row and simultaneously place all columns, using Set All.

This procedure can also be carried out using Edit MIB Vars.. in the Manage menu. In this case, click through to the table, single-click on the column to be placed, enter the index in the field Variable Name after the name of this column and the new value in Variable Value. After clicking Set, a new table row should appear.

Error messages via SNMP trap

Error or warning messages can be sent to a manager using the SNMP mechanism. The SNMP agent contained in the router permits traps to be sent to up to 20 SNMP managers. The IP addresses of these managers are configured in the Configuration menu under /setup/SNMP-module/IP-Trap-Table. You can enable and disable the trans- mission of trap messages using the /setup/SNMP-module/Send-Trapsswitch.

The Management Information Base (MIB)

A textual representation of the configuration structure (the so-called private MIB) must be supplied with the ELSA MicroLink Cable so that the SNMP management system can access its configuration. The syntax of this MIB complies with ASN.1 (Abstract Syntax Notation One, ISO 8824). There is usually a so-called MIB compiler included with the SNMP management software. This compiler converts the MIB file into a form that can be used by the manager.

The current ELSA MIB can be found both included with the product on CD and in the ELSA online media.
