| Description | If CEF is enabled on the managed device, then each
entry represents a longest Match Prefix request.
A management station wishing to get the longest
Match prefix for a given destination address
should create the associate instance of the
row status. The row status should be set to
active(1) to initiate the request. Note that
this entire procedure may be initiated via a
single set request which specifies a row status
of createAndGo(4).
Once the request completes, the management station
should retrieve the values of the objects of
interest, and should then delete the entry. In order
to prevent old entries from clogging the table,
entries will be aged out, but an entry will never be
deleted within 5 minutes of completion.
Entries are lost after an agent restart.
I.e. to find out the longest prefix match for
destination address of A.B.C.D on entity whose
entityPhysicalIndex is 1, the Management station
will create an entry in cefLMPrefixTable with
cefLMPrefixRowStatus.1(entPhysicalIndex).1(ipv4).A.B.C.D
set to createAndGo(4). Management Station may query the
value of objects cefLMPrefix and cefLMPrefixLen
to find out the corresponding prefix entry from the
cefPrefixTable once the value of cefLMPrefixState
is set to matchFound(2).
entPhysicalIndex is also an index for this
table which represents entities of
'module' entPhysicalClass which are capable
of running CEF. |
