Capture Multiple Trace Files From Several Interfaces With Cisco Application Analysis Solution (OPNET)

CAAS and OPNET ITGURU only allow you to capture from one interface at a time from the OPNET agent. If you use the DNS name and the IP address you can capture two interfaces, but what do you do if there are three interfaces?

Custom HOSTS editing will let you resolve the same IP address to different names, here are a few pointers on doing this:

Go to
C:\windows\system32\drivers\etc

edit the HOSTS file with notepad or something like vi.

format is IP address TAB desiredname

for example:
Use the last MAC address octet to differentiate.

127.0.0.1 localhost
192.168.1.29 SERVER-1A.COMPANY.INTERNAL.COM
192.168.1.29 SERVER-19.COMPANY.INTERNAL.COM
192.168.1.29 SERVER-23.COMPANY.INTERNAL.COM

This gives you a UNIQUE dns type name to resolve to and when picking the interfaces in the GUI you will be able to check and refer to the correct one with the MAC octet for that interface.
