mgmdRouterPerEntCacheTable

The (conceptual) table listing the interfaces that are
members of a particular group.
          
There are two MIB tables that are suitable for reading (G,I)
state - mgmdRouterCacheTable and mgmdRouterPerEntCacheTable.
These tables contain the same objects, but their indexing is
different.
          
For IGMP snooping, the administrator must read the
mgmdRouterPerEntCacheTable.  The mgmdRouterCacheTable is not
supported (because a single row in that table would
correspond to multiple objects, one per bridge domain).
          
When not performing IGMP snooping, the administrator can use
either table.  In systems in which there are a large number
of Router entities, there might be a performance benefit to
using the mgmdRouterPerEntCacheTable for queries for which
only a subset of Router entities are of interest.
          
For example, if an entity index corresponds to a particular
line card, and the administrator is interested in (G,I)
state for only one line card, then walking this table for a
particular entity index returns the (G,I) state for the
interfaces on that line card only (whereas
mgmdRouterCacheTable returns (G,I) state for all interfaces
on the device).
          
(The possible performance benefit arises because to get the
rows in mgmdRouterPerEntCacheTable, MIB Manager queries a
single Router entity per row, whereas to get the rows in
mgmdRouterCacheTable, MIB Manager queries every Router
entity per row).
