I have problem with EtherChannel Bonding. Where I have no problem in
setting it up (according to the procedure given in the SAG) and it
works fine under light load. However, I have the following two
findings.
1. The throughput is much slower than using single NIC.
2. I have checked the ethereal log that there are a log of ACK and even
Segment lost. In addition, there are a lot of DUP ACK also.
I have tried to connect my server onto two different switch (planet and
cisco 2970) which is a hundred and giga switch but unfortunately I got
problem with both switch.
I have tried to change the setting (mode=1 and mode=5 or mode=6) but
without luck, the same thing happened.
Pls find below the setting of /etc/modules.conf
alis bond0 bonding
options bonding miimon=100 mode=1 updelay=5000 arp_interval=1000
arp_ip_target=10.1.1.1 use_carrier
where 10.1.1.1 is the other host and it is also a RHEL ES 3 while it
just has a single leg and I am trying this test on a separated
environment.
