The -L flag was dropped in V6 (made a no-op) because it was no longer
needed. This is because, according to the internal update I attended,
32-bit masks are now fully supported; 32-bit masks are generally used for
software loopback interfaces. The connection is not exactly clear to me,
but I have seen loopbacks discovered successfully in V6, whether the
loopback was the address specified in the seedfile or not. So by my
voodoo-problem-determination methodology, I would suggest checking
the mask on the loopback that is missing. If it is not 255.255.255.255,
make
it so. If it is already so, look for some other, more mundane discovery
problem, or call Support with a trace of the discovery handy.

Subject: [NV-L] What happened to netmon Flag?
AIX 4.3.2, NV 5.1.2 and NV 6.0
in version 6.0 of netview it seems that one flag of netmon (-L, discover
loopback interfaces with other address than 127.0.0.0) was withdrawn.
I have a Cisco 1600 with loopback interface 10.10.224.85 and three other
interfaces
Demand poll with NV 5.1.2 (netmon runs with -L):
Interface 10.10.232.86 (currently up) responded to ping
Interface 10.10.21.1 (currently up) responded to ping
Interface 10.10.224.85 (currently up) responded to ping
Interface 10.10.240.86 (down since 07/03/00) ping timed out
Demand poll with NV 6.0 shows:
Interface 10.10.232.86 (currently up) responded to ping
Interface 10.10.21.1 (currently up) responded to ping
Interface 10.10.240.86 (down since 07/03/00) ping timed out
So it looks like netmon V6.0 doesn't discover the loopback interface I'd
like to see. Does that work as designed? Did I miss anything? Can I use an
undocumented "-L feature"?
Any help is very welcome...Andreas
