Hello Centos People, I have a CentOS 5.3 box that had a total of 5 ethernet cards in it. It functions to share an internet connection with 4 different subnets. All works fine, except I'm noticing that my MRTG traffic graphs are wrong. Further digging with snmpwalk reveal that the order of the ethernet interfaces changes every time the machine is rebooted to a different order. For example, I currently see: IF-MIB::ifDescr.1 = STRING: lo IF-MIB::ifDescr.2 = STRING: eth3 IF-MIB::ifDescr.3 = STRING: eth4 IF-MIB::ifDescr.4 = STRING: eth0 IF-MIB::ifDescr.5 = STRING: eth1 IF-MIB::ifDescr.6 = STRING: eth2 IF-MIB::ifDescr.7 = STRING: sit0 Why is this not in proper order? Other servers seem to be ok. my snmpd.conf file has little, if anything as far as config. Is there something I need to put in there for persistence? Bob
