Network Discovery not populating hostname

Unanswered Question

I have 2.6 setup and I'm having problems with the hostname not populating in my device lists. After running a discovery in Campus Manager, the only thing that is populated in the DCE is the IP address for the hostname, IP address, and Display Name. I know that it can poll the hostname because it shows up in the DME inventory details.


This is part of a secondary problem that I'm struggling with. I'm trying to find a way to create custom groups based on the hostname.


Is there anything that I need to change in CW or on the devices themselves. They have SNMP, CDP, VTP, and Syslog setup, but not DNS.


Thank you

You need to verify that the management IP address (i.e. the one in DCR) is properly resolvable to a hostname using the NMSROOT/bin/resolver.pl utility:


NMSROOT/bin/perl NMSROOT/bin/resolver.pl


Once the IP is resolving properly to a hostname, that hostname should be updated in DCR upon a successful Device Discovery. To get the display name to update in DCR, you will need to set nameserver.updateDCRDisplayName=true in NMSROOT/campus/etc/cwsi/DeviceDiscovery.properties, then re-run Discovery.
