Greetings,
I put an append on a few days back with a throwaway comment about "no
real new functionality in Fixpack 3" - WRONG!
There is a feature called "Custom Links" which, I believe, has been
developed to help the new layer 2 visualisation in the new IBM Tivoli
Switch Analyzer V1.3. This works very nicely regardless of whether you
have ITSA.
The idea is that if you have a part of your network that you have no
SNMP access to (like if you FM your network) then you can discover nodes
at the "far side" of your network with entries in the seedfile, but you
get 2 (or more) disconnected parts of network. Custom links allow you
to create a logical link or tunnel across an unmanaged region - it looks
similar to an unnumbered serial link and is represented by a dot-dash
line on the GUI, so you can tell which are manual links.
The only issue is that the documentation is inconsistent between the NV
7.1.4 FP3 readme and the ITSA 1.3 Release Notes.
It seems to work fine but the NV 7.1.4 FP3 readme says to supply:
@link <ipaddress>:0:<ipaddress>:0 where the "0" is the ifIndex
The ITSA Release Notes say "both zeros are required". I have found that
the ifIndex MUST be 0, otherwise the link isn't made. Always use "0"
and it seems to work out what actual ifIndexs are necessary. Also,
don't miss out the ":" in the middle as I did for quite some time!!
netmon -y picks up seedfile @link entries fine. I find that I have to
demand poll the "far" end to get the connection added - polling the
"near" end didn't establish it.
Enjoy!
Jane
