Description: This table is taken directly from the Q-BRIDGE-MIB.
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.
