hi Alex, All, try running cfgmaker again in the switch. cfgmaker will find all the interfaces (ethernet1, 2, 3...), and all the port channel (i.e. eth1+eth2) as one interface. in the cfg file, the port channels will be named as they are in the switch, port channel 1, port channel 2.
hope that helps. if not, send me amessage, and i can send to you a example cfg file. but, again, cfgmaker do all the work for you. regards.

I have mrtg monitor each of the 2 interfaces fine, but i wanted to add a graph with a sum of the interfaces : this is the way i have defined it now : WorkDir: /var/www/html/mrtg Options[^]: noinfo, Options[_]: bits Target[BandwidthCombined]: 3:[EMAIL PROTECTED]:::::2 + 4:[EMAIL PROTECTED]:::::2 SetEnv[BandwidthCombined]: MRTG_INT_IP="" MRTG_INT_DESCR="Outer trunks : combined bandwidth" MaxBytes[BandwidthCombined]: 25000000 Title[BandwidthCombined]: Outer trunks : combined bandwidth PageTop[BandwidthCombined]: <H1>Outer trunks : combined bandwidth</H1> (it is now using snmp ver 2, i read in the list that this could help my problem, but it doesn't). each of the ports are monitored in a standalone graph : Target[2]: 3:[EMAIL PROTECTED]: SetEnv[2]: MRTG_INT_IP="" MRTG_INT_DESCR="FastEthernet0/2" MaxBytes[2]: 12500000 Title[2]: Upstream trunk connection 2 PageTop[2]: <H1>Upstream trunk connection 2</H1> Target[3]: 4:[EMAIL PROTECTED]: SetEnv[3]: MRTG_INT_IP="" MRTG_INT_DESCR="FastEthernet0/3" MaxBytes[3]: 12500000 Title[3]: Upstream trunk connection 3 PageTop[3]: <H1>Upstream trunk connection 3</H1> Unfortunatelly, the aggregate graph does not display anything above 100MB, even through i do see in the log entried that approach 120 mb and more (and the sum of the channels measured separatelly is around 120 MB from time to time) sample from the log : 1053520502 1919519777081 36176746333441 <snip> 1053440100 751704 11631086 751884 11631086 1053439800 698450 11631086 802212 11631086 1053439500 802130 11631086 802212 11631086 1053439200 777752 11632816 800410 12150128 1053438900 800218 12150128 800410 12150128 1053438600 742855 12150128 742855 12150128 1053438300 743752 12150128 796677 12150128 1053438000 796040 12150128 796677 12150128 1053437700 733094 12150128 762955 12150128 1053437400 762819 12145702 762955 12150128 1053437100 722087 10822477 722160 10822477 1053436800 704566 10561430 711232 10822477 1053436500 639491 8025555 639814 8025555 1053436200 543163 8026463 555362 8298191 it seems that the info is collected correctly, but is not graphed correctly : the graphs are at : http://206.82.140.186/graphs/index3.html from the graph of the combined bandwidth you can see that the combined bandwidth did not exceed 100 mb at 16:30 yesterday, but the sum of the trunks was much higher i am running mrtg-2.9.29 on linux. I would apreciate any ideas you could give me - this is a magor problem. Thank you, --- Checked by AVG anti-virus system (http://www.grisoft.com).
