Mark, check for reverse name resolution on those extra addresses. That
would do it,
if they were ever up.  I take it that you have pulled the address table for
that device
and they don't show up there (monitor..network configuration..addresses)?
If they are
not in the address table, netmon had to hear from them at some point, maybe
on a
PC, and it would then lookup those addresses. If they resolve to a router,
it will add
them.

Cordially,

Hello to the List,

I've encountered puzzling interface discovery behavior and hope someone
here
can enlighten me as to what's going on.  I'm running NV 6.01 on AIX 4.3.3.

Netview has (re)discovered one of our Cisco 4500 routers with three normal
and two critical interfaces where we believe there should be only three
normal interfaces.  This router has four Ethernet interfaces, and one
FastEthernet interface.  Two of the Ethernet interfaces are admin down with
no ip addresses configured.  Status of the two configured Ethernet and the
fast Ethernet interfaces is normal.  The router does have several static
routes configured, including one to the 198.179.249.250 address Netview
assigned to a bogus interface.

My question(s):  Why has Netview discovered two extra Ethernet2 "critical"
interfaces with bogus MAC addresses and put ip addresses on them? What can
I
do to remedy this condition?

Here's part of the ovobjprint -s of the router.  I have the "red"
interfaces
unmanaged to keep the bogus status from propagating.
