Description: This table is taken directly from the IF-MIB (MIB-II). However, it has been slightly modified by adding an extra indice (by switch)[[ and adding a prefix so as not to conflict with the pre-existing namespace]]. We want to be able to capture the data from all switches within the chassis, thus can't easily incorporate within the main table as data differs by switch and by the chassis, itself. Thus, the main group reflects the chassis, and this table reflects the switches. Otherwise it is identical.

Extension to the interface table

This table replaces the switchIfExtnsTable table.

A list of interface entries. The number of entries is given by the value of switchIfNumber. This table contains additional objects for the interface table.
