Check what the interface speed is with 'mii-tool eth0'. If you're
plugging in to a Cisco switch, for some reason, most do not want to
auto-negotiate to Full Duplex. Manually set all ports on it to full
duplex then manually set your nic with mii-tool to full
duplex as well.
No, with gigabit devices the tool is ethtool. Mii-tool is not being
developed anymore and has no support for any gigabit device, even in
100
megabit mode.
I was plugging into an extreme 24e2 switch, which was uplinked to an
extreme 1i router. It was the connection between the 24e2 and the 1i
that was bad. I plugged the LVS machine directly into the 1i, set the
port to auto-negotiate on the 1i and the LVS machine, and linked up at
1000baseT FD. Quite nice. Testing without the css in the mix showed I
was indeed able to saturate the link. Awesome.
Still, I wonder if there's a way other than firewall rules on the
realservers, hosts entries, etc, to allow realservers to be clients to
the VIP. The current plan is to recode the software that relies on it,
but I'd like to have the feature available if it becomes necessary
later.
