I hope this response isn't too late to be of help.  Looks like my mail
server lost this one after a failover

Now I know nothing about this Interface Marginal problem, per se, but have
you checked the database status of these objects?  Does it correspond to
the color or not?  That would help isolate whether the issue is with the
ovw/ipmap GUI or with netmon.   If the status matches the color, then the
source is most likely netmon, since he'd be the one setting the status (I

If it appears to be netmon, have you tried looking at the netmon.trace in
You can turn on full tracing with "netmon -M -1" from the command line, and
off again with "netmon -M 0".
That might give you a clue as to what is going on.

Hi all,

I am running Netview 7.1.4 FP03 on AIX (4330-11)

I have come across a problem since upgrading from 7.1.2 whereby interfaces
on some of my cicso routers are turning yellow - marginal for no apparent
reason.  When I ping them they can ping OK but remain yellow until I
manually unmanage then manage the interface,  then the interface goes green
for a period (up to 30 minutes) then goes yellow again.  Sometimes the
router icon goes yellow although all the interfaces are OK (green), again
unmanaging and managing the router corrects the problem briefly.

I will shortly be opening a PMR on this anyway as my Network support team
here are losing confidence in the product, but thought I'd ask the list
first if anybody has seen this before?

This is happening on a number of different cisco routers on a number of
different interfaces (loopback, serial and ethernet).

If I may, one supplimental question… How is it possible for a leaf
interface to be marginal? (I'm sure I am missing something here :-))
