If possible, ntop creates a single 'device' which picks up the 1st interface name. But all data is combined into the single device. When you have the virtual devices (sFlow, netFlow), ntop can't enable the merge and so it creates one 'device' structure per physical/virtual interface. > Also, I thought I recalled from earlier versions of NTOP that if I used > Admin -> Switch NIC, once I was on another NIC, if I went back to a > previous one all the data was lost. Is this correct? Is it still an issue? Nope, never was a problem and isn't. > > Thanks for the help... > -- > Andrew Davis > North County Computers > http://www.nccomp.com > > Email: [EMAIL PROTECTED] > Local: 760-525-4689 > Toll Free: 877-735-4689 > > <a href="http://www.nccomp.com";>North County Computers</a> > > _______________________________________________ > Ntop mailing list > [EMAIL PROTECTED] > http://listgateway.unipi.it/mailman/listinfo/ntop _______________________________________________ Ntop mailing list [EMAIL PROTECTED] http://listgateway.unipi.it/mailman/listinfo/ntop
