Tying up Port Login table entries with Port Table Entries in CISCO SNMP

In a monitoring app I am writing I plan on using SNMP to obtain
for each port on an MDS9000 CISCO switch the remote host WWN and
remote port WWN, with the aim of producing a table as follows:

Port Port Remote Remote
No WWN Host WWN Port WWN
1 a.b.c d.e.f g.h.i
2 j.k.l - - <-- not connected
3 m.n.o p.q.r s.t.u
:::::::::::::::::::::::::::::


I _thought_ this information could be obtained by referring to
a couple of tables in CISCO-FC-FE-MIB:

* The Port table, which is .1.3.6.1.4.1.9.9.289.1.1.2, i.e.
ciscoFcFeMIB.ciscoFcFeObjects.cffFcFeConfig.fcIfTable.
and has a single index.

* The Port Login Table, .1.3.6.1.4.1.9.9.289.1.1.5, i.e.
ciscoFcFeMIB.ciscoFcFeObjects.cffFcFeConfig.fcIfFLoginTable,
which has three indexes.

The first table has an element for every port, and the second
table has elements only for connected ports. But, contrary to
what I initially expected, the index values don't match!

(Both these indexes are called 'ifIndex'; but it seems this is
just a generic name, i.e. index type.)

So can anyone suggest a way of tying up each Port Login Table
entry with the correct Port Table entry?
