Redhat bonding with two switch

  • 772

I have a server running RHEL6 with two NICs, each connect to separate switch. Two Cisco 3560 switches connected with a trunk link. The problem is the bonding link is not stable (lost some packets). When I unplug cable from 1 uplink from server to switch, many packets had been lost (about 50%). I've tried with all of Redhat bonding mode but cannot solve my problem. My question is: Can I do it and how?

Thanks in advance, giobuon

  1. I do this very thing.. In your modprobe.conf (if your using redhat 6) do you use Mode 6, and what do you set your miimon to? I set mine to 80ms..

    I like mode 6, it makes things just work... Less throughput, but easy to survive a switch failover (also, with some of the 'fancy' modes, we couldn't do it to two seperate dell switches, even in a virtual chassis.)
