Some Devices are not showing up at all in the Discovery reports

[Mohammed Tolib]

Hi all,

The first time I ran the CS device discovery I got 50 reachable devices. I scheduled the Device Discovery to be run every week. I added more subnets to the discovery but unfortunately the last discovery shows only 31 devices from the first discovered devices (50). I checked the DCR and there is only 44 devices out of the 50!

My question is:

Should not the scheduled Device Discovery discovers all devices -the previously discovered ones and the new ones-?

Why the rest of the devices are not showing up at all in the discovery reports (neither reachable nor unreachable) although all of them are pingable and responding to the snmpwalk tool from the CWLMS server.

Your kindly respond is highly appreciated.

Thanks in advance.

try to double check if the schedule discovery has the same settings as the immediate one.

because changing the discovery settings will not be reflected into the already scheduled ones.

also try to run the discovery again using immediate and schedule compare both results and see how it goes.

I ran the discovery again with the same settings after enabling debugging and I checked the following log files:

1. in the ngdiscovery.log I found a lot of errors all about Duplicate IpAddress example:

ERROR  [DeviceManager : EvalTask-DiscoveryThreadPool-06 addNewDevice]  : Duplicate IpAddress (127.0.0.51) found in addNewDevice().Device 1 ip = 10.8.113.29 , id1 = 127.0.0.51*F1COR.xyz.com*.1.3.6.1.4.1.9.1.283, Device 2 ip = 10.8.113.106 , id2 = 127.0.0.51*LCD.xyz.com*.1.3.6.1.4.1.9.1.283

ERROR  [DeviceManager : EvalTask-DiscoveryThreadPool-08 updateDevice]  : Duplicate IpAddress (127.0.0.51) found in updateDevice().Device 1 ip = 10.8.113.93 , id1 = 127.0.0.51*UDS.xyz.com*.1.3.6.1.4.1.9.1.283, Device 2 ip = 10.8.113.73 , id2 = 127.0.0.51*F2COR.xyz.com*.1.3.6.1.4.1.9.1.283

ERROR  [DeviceManager : EvalTask-DiscoveryThreadPool-09 addNewDevice]  : Duplicate IpAddress (10.8.113.42) found in addNewDevice().Device 1 ip = 10.8.113.42 , id1 = null, Device 2 ip = 10.8.113.86 , id2 = 10.8.118.251*OPS.xyz.sa*.1.3.6.1.4.1.9.1.501

2. in the CSDiscovery.log:

Error while changing the permission of the file C:\PROGRA~1\CSCOpx\objects\csdiscovery\1348\DiscoveryStatusObj

I checked the file and the casusers has a Modify permission

My Question is:

1. what is the meaning of those output exactly?

2. If CWLMS found duplicatedd IP address how it works in terms of (ignoring, updating existing devices, Adding the new devices, ... etc)

Many thanks for your help.
