As you can see mii-tool shows 100 FD while ethtool says 1000 Mb/s. Because of the "Advertised link modes" and the "Advertised auto-negotiation", on your outout, I would tend to think that the switch port is hard coded to 100 Mb/s.Jacob wrote:Thank you for your reply, I didnt know that :-)HeyWhat is the output from "ethtool eth2"? mii-tool won't show speeds above 100-FD.
I've got a wierd thing here... I've installed CentOS v. 4.4 on a MSI PT880-NEO-FSR motherboard.
On it theres a gbit LAN adapter, Centos installs it and it works perfectly... but only at 100mbit fd... ?
Output from lspci:
00:07.0 Ethernet controller: VIA Technologies, Inc. VT6120/VT6121/VT6122 Gigabit Ethernet Adapter (rev 11)
Output from mii-tool
eth2: negotiated 100baseTx-FD , link ok
I've tried mii-tool -r to re negotiate link speeds and duplex, but it doesnt help... neither does a reboot. The adapter is offcourse plugged in to a gbit switch. Theres two other computers in the same switch who can communicate with speeds up to 1gbit. I've also tried plugging the server into another switchport without any changes.
I've also tried to force the adapter to 1000mbit fd.... but that gives:
ethtool -s eth2 speed 1000 dulpex full
Cannot set new settings: Invalid argument
not setting speed
not setting duplex
Anyone got a clue ? :-)
Best regards Jacob

Hello again.
I will use ethtool from now on :-)
The switch is a simple dummy 5 ports 10/100/1000mbit switch, and i cant configure it to any specific speed... :-(
Regards Jacob
What driver is loaded for each link?
ethtool -e eth0
ethtool -e eth1
ethtool -e eth2
What are the lines in /etc/modprobe.conf that refer to the ethernet devices?
What does ifconfig say?
Ken
