hlMatrixControlTable OBJECT-TYPE
SYNTAX SEQUENCE OF HlMatrixControlEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A list of higher-layer (i.e., non-MAC) matrix control entries.
These entries will enable the collection of the network- and
application-level matrix tables containing conversation
statistics indexed by pairs of network addresses.
Both the network- and application-level matrix tables are
controlled by this table so that they will both be created
and deleted at the same time, further increasing the ease with
which they can be implemented as a single datastore. (Note that
if an implementation stores application-layer matrix records
in memory, it can derive network-layer matrix records from
them.)
Entries in the nlMatrixSDTable and nlMatrixDSTable will be
created on behalf of each entry in this table. Additionally,
if this probe implements the alMatrix tables, entries in the
alMatrix tables will be created on behalf of each entry in
this table."
