| Description | A trace route request entry.
A management station wishing to create an entry
should generate a pseudo-random number to be
used as an index into this table and create an
instance of the fcTraceRouteRowStatus object.
After that, the management station should set
the corresponding instance of fcTraceRouteTargetAddr
object with the address of the destination for which
the route needs to be determined and
fcTraceRouteVsanIndex with the desired VSAN number.
Once the appropriate instance of all the
configuration objects have been created, either by
an explicit SNMP set request or by default, the row
status should be set to active and the corresponding
instance of fcTraceRouteAdminStatus should be set to
'enable' to initiate the trace route sequence. Note
that this entire procedure may be initiated via a
single set request which specifies a row status of
createAndGo as well as specifies valid values for
the non-defaulted configuration objects.
The results of the trace route operation are made
available in the fcTraceRouteHopsTable. For an entry
uniquely identified by fcTraceRouteIndex, the value
of the corresponding instance of
fcTraceRouteOperStatus object will specify whether
test was a success or a failure.
The fcTraceRouteHopsTable will contain the actual
hops that were determined by the test.
For an entry uniquely identified by
fcTraceRouteIndex, entries will be created
automatically in the fcTraceRouteHopsTable which
contain the different hops of the trace route path.
Once the trace route test is complete, the management
station should retrieve the information from the
fcTraceRouteHopsTable and delete the entry from this
table. When an entry is deleted from this table,
related entries in the fcTraceRouteHopsTable will be
automatically deleted by the agent.
In order to prevent old entries from clogging the
table, entries will be aged out. But an entry will
never be deleted within fcTraceRouteAgeInterval
milliseconds of completing.
If the management station wishes to repeat the trace
route test for a particular destination, then it will
need to set the corresponding instance of
fcTraceRouteAdminStatus to 'enable' again. |
