Attempting to bond two hosts through a cisco WS-C3750X-24T-S   and then do a transfer test. I wanted to see the differnces and caveats of mode 0 round robin vs mode 4 LACP and modes 5 TLB and 6 ALB.

I've tried both and my results are identical to a single NIC no bond.

I;ve been using nc (netcat to test)

time cat test_500mb | nc 192.168.0.125 7778 #on host 1

nc -l -p 7778 > /dev/null #on host 2

LACP is routed by mac addresses, so a point to point transfer test or using

a gateway will only use 1 slave device!!!

LACP 1 transfer 2 slaves active:

112MB/s

900mbs

LACP 1 transfer 1 slave active:

112MB/s

900mbs

LACP 2 transfers 2 slaves active:

112MB/s

900mbs

LACP 2 transfers 1 slave active:

112MB/s

898mbs

Round Robin 2 transfers 2 slaves active:

112MB/s

900mbs

Round Robin 2 transfers 1 slave active:

112MB/s

898mbs
