The general answer is "no". You cannot see the same trap twice, once with a hostname and once with an IP Address. NetView uses name resolution wherever possible, and displays a particular trap only once.
However, certain traps such as NetView's Interface Down/Up contain the IP address as a separate varbind, varbind 7,and you can modify the trap format in trapd.conf, using xnmtrap, to display both. For example, the current format for the Event Log message for IBM_NVIUP_EV (58916866) is given as simply "$3", which is the 3rd varbind. Netmon supplies it as "Interface <name> up". But you could add to it, say for example,
"$3. IP ADDRESS = $7"
and the event should display showing the IP Address as well. You could change the IBM_NVIDWN_EV (58916867) in a similar fashion.
For Node Up/Down events (58916864 and 58916865), varbind 8 contains a comma delimited list of all the interfaces on the node. You could alter those events to display that list if you desired.
For non-NetView vendor events you are restricted to whatever they send in their traps.
You can learn more about the contents of NetView internal traps in Appendix A of the Administrator's Guide. I'd use the 7.1.5 documentation even if you have 7.1.4, because it was rewritten to be more complete and a number of old errors were expunged. It's more likely to correct than the 7.1.4 doc, even if it documents a couple of traps you don't have.

Hi,
Thanks for your reply. I understand what you said but my question is whether i can able to get two entries at the same time in trapd.log, one with IP address and another with hostname when an event occurs.
Thanks & Regards

Subject: Re: [NV-L] Traps by hostname
If you get a NetView trap which is not resolved, then you have a DNS problem. Most likely the reverse look-up, IP address to hostname, is missing. Both netmon and trapd do everything they can to use hostnames rather than IP addresses in the traps which netmon sends and trapd displays. If a NetView trap, e.g., Node Down, shows up in trapd.log with an IP address instead of a hostname, then it's a fact that netmon's gethostbyaddr call failed to provide one.
The same is true for a non-NetView trap. If a non-NetView trap is shown in trapd.log with an IP address rather than a hostname, then trapd's gethostbyaddr call failed to provide one.
Try using the nvgethost command in /usr/OV/bin. You should get the same results when you use the hostname and when you sue the IP address. If they differ, then you have a problem to resolve.
