Description: A table of destination filters set up in the switch.
New filters are created by adding entries to this
table.  Note that values for all of the relevant objects
for a particular type of filter must be specified in a
single SNMP set operation on creation of a filter.  Set
operations which do not contain all of the required objects
for a given filter type will fail with an error-status
of 'genErr'.  The objects required for each filter type are
as follows:

ciscoTsMACDestFilterType   |   Required Objects for Creation
========================   |   =============================
block-dest(1)              |   ciscoTsMACDestFilterPorts
---------------------------|--------------------------------
allow-dest(2)              |   ciscoTsMACDestFilterPorts
---------------------------|--------------------------------
limited-multicast(3)       |   ciscoTsMACDestFilterPorts
                           |   ciscoTsMACDestFilterExitMask
---------------------------|--------------------------------
force-dest(4)              |   ciscoTsMACDestFilterPorts
                           |   ciscoTsMACDestFilterRemoteBox
                           |   ciscoTsMACDestFilterRemotePort 

Since the indices for the table are switch number, MAC
address, and filter type, the instance information for a given
object specifies which filter is being created.  For example,
a set request for

      ciscoTsMACDestFilterPorts.s.a1.a2.a3.a4.a5.a6.t

will create a filter of type 't' (as enumerated for
ciscoTsMACDestFilterType) for MAC address a1:a2:a3:a4:a5:a6
on switch number 's'.
