Chapter 2 - MIB Structure and SNMP Tables

Mediatrix 4100

Tables

There are two types of tables used in the MIB structure. They contain:

 Generic variables that apply to each line of a unit. This avoids to repeat each set of variables

for each line it has.

 The administrative commands and status related to a managed object.

Generic Variables

All tables used to set variables for one or more lines (such as the voiceIfTable) are based on the ifTable, or

interface table.

The ifTable lists the interfaces of a unit. In other words, it basically defines the lines that are used by the unit.

It contains an ifIndex, which defines the interfaces. It may also contain interfaces such as:

 the LoopBack (lo) and Ethernet (eth0) interfaces.

 the actual voice interfaces (lines) of the unit.

Table 17 gives an example of the ifTable.

Figure 12 shows a table built in the Unit Manager Network from the voiceifTable parameters.

You can perform GET and SET operations on these parameters.
