Thanks for answer, It has helped not much but I hope we solve this
together. These information generates cfgmaker

C:\mrtg-2.15.0\bin>perl cfgmaker public at --global "WorkDir: d:\htdo
cs\mrtg" --output mrtg.cfg
--base: Get Device Info on public at
--base: Vendor Id:
--base: Populating confcache

--coca: Skipping ifName scanning because public at does not seem to
support it
--coca: store in confcache public at Ip --> 103

how get I these information with any application from net-snmp?

in attachment last sent there is all what I get with snmpwalk from my
router. There is something with 102 but nothing with ifInOctets. So
how is possible that mrtg shows graph for IP on interface 102 with
up/dn statistics? I want this also in cacti but only for upload.

Please help (I will try any command you send me and send you any
output you wish)
