Mike, Can you open a PMR on this? The last PMR I opened was PMR 91969. My work email address and contact number should still be in your system. Stephanie Cornish

Leslie,
My seed file includes routers and switches. I ran ovobjprint and ovtopodump to search for the first 3 octects of the IP addresses. I turned netmon trace on with a -1 trace mask value. I've tried forcing NetView to discover these devices by doing an extended ping from the command line. Here's some output from netmon.trace:
14:49:27 : ./nl_pinger.c[1519] :
revc_icmp: deleteMatchIp returns null!
14:49:23 : ./nl_hint.c[295] : Addhint(172.18.117.130,0.0.0.0) Best guess network is <null>
14:49:23 : ./nl_hint.c[306] : Addhint(172.18.117.130,0.0.0.0) rejected (no network for IP addr)
14:49:23 : ./nl_pinger.c[1559] : -> received unexpected ping, ident=8909 seq=33, from 172.18.117.130
I ran "ovtopofix -a" and have the rw map.
I've done everything possible to get these devices discovered. What are your thoughts?

You don't even need SNMP access to get them discovered. So something more basic is wrong.
Is this a Unix or a Windows
server?
Check these things:
1) If you are using a seedfile, does it exclude the range of addresses that you are trying to discover?
2) Have you tried putting the router and switch addresses in the seedfile?
3) Is the map you are looking for them in a r/w map up?
4) Are you sure they are not in there already, maybe on some other node than you expect?
For that last one, try
nvUtil e '("SNMP ipAddress" = "xx.xx.xx.xx")'
5) Remember that a range in the seedfile only allows discovery, it does
not force discovery. If they are found in the arp cache of an existing device, and they are allowed by the seedfile, they should be discovered.
6) Be sure you are not discovering by a virtual address. Try using the loopback address of the device. To tell if you are using a virtual, try
rnetstat -Ix xx.xx.xx.xx
and check the output to see if that address is in the list of addresses on the device. If it is missing, Netview will discard the node.
7) If you have more than one map, and the things were previously discovered in one of them, they must be deleted from all maps before they can be rediscovered.
8) Do these commands to reorg things that might have
gotten out of wack:
ovstop netmon
ovtopofix -a
ovmapcount -a
ovstart netmon
close and open the map

All,
I have 2 routers and 2 switches
on the same subnet which NetView 7.1.4 won't discover. Each device is reachable via Ping and each one responds to SNMP polls.
Can someone let me know which MIB objects NetView reads and uses in order to add new subnets and /or devices?
Thanks In Advance,
Stephanie
