Gary is right. The interface merge switch basically creates only ONE set of counters. And then all traffic is counted in them.
If the switch is not set, then a separate set is created for each one. It would certainly be possible to create some form of the switch that would allow a partial merge and then chase the switch through the code implementing it. Probably only a few dozen lines. But it's not there today. --merge-interfaces=tap1(eth1,eth2),tap2=(eth3,eth4) type syntax. -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brooks, Jason Sent: Friday, November 07, 2008 7:13 PM To: ntop@unipi.it Subject: Re: [Ntop] merged but separate interfaces Thanks!
