Hi,
I have two network cards that are both displaying as such:

dbadmin@livedb:~$ sudo mii-tool
eth0: no autonegotiation, 100baseTx-HD, link ok
eth1: no autonegotiation, 100baseTx-HD, link ok

I have bonded them in modprope.d as such:

alias bond0 bonding
options bonding mode=0 miimon=100 downdelay=200 updelay=200

However the bonded interface is only 10Meg Half duplex:

dbadmin@livedb:~$ sudo mii-tool bond0
bond0: 10 Mbit, half duplex, link ok

Why is this? Is it safe to use 'ethtool -s' to increase the speed of
the bonded interface? I don't want it to crash as the server is hosted
elsewhere and would involve a long trip to fix!

Thanks in advance,
Birju

Greetings Birju:

I don't think that I would believe the statistics that mii-tool is
reporting. I have a similar setup - two NICs bonded into a single
channel. Both adapters are 1Gb, connected into a Gb switch:

mii-tool
eth0: negotiated 100baseTx-FD flow-control, link ok
eth1: negotiated 100baseTx-FD flow-control, link ok


mii-tool bond0
bond0: 10 Mbit, half duplex, link ok

I know for a fact that the interfaces are running at 1Gb, and the bond
averages about 600 Mb/sec.

You might try pushing a large file onto the box with scp or a similar
tool that will report the time that the copy takes, just to verify your
speed is greater than 10Mb.
