Hi, After deploying some new Dell PowerEdge 1950 running RHEL 5.2, I've seen the following problem : The cacti/snmp graphs for a bonded interface made from the two ports of a dual PCIe Intel NIC were wrong.
After investigating, here's what I currently see : - The values ifconfig reports seem wrong too - The values found in /proc/net/dev seem wrong too - Using "iptraf", I don't see the bonded interface, but the values for the two physical interfaces seem good (!?) Values : - From snmp : 800Mbps for both eth2 and eth3, 1.6Gbps for bond1 - From ifconfig and /proc/net/dev : About 100MB/s for the eth and 200MB/s for bond1 (rough estimate, but matches what's seen with snmp) - From iptraf : 190Mbps for both eth2 and eth3, which means a total of 380Mbps, which is the much more realistic value and about 1/4th of the value reported by snmp/ifconfig. The system has been installed as 32bit and is running the 2.6.18-92.el5PAE kernel, as x86_64 was not an option here. The bonded interfaces are using the e1000 kernel module. Does this problem ring a bell to anyone? I don't recall seeing it before, but I don't think I've ever had a 100% identical setup, which could explain.
