Hi,
Before I get too stupid and spend hours/hours looking into things... would a 1 Gigabit card running r8169 driver get stuck @ 100 speed?
Everything works fine except the speed.
I want to set up jumbo frames on my LMCE network because my MD's are not the fastest CPU's.
I was hoping to increase the frame size, reduce my CPU processing and improve my data transmission speeds.
I have one device in the network which is connecting @ 100Mbps @ the switching hub but "spec-wise" has a gigabyte card.
Other devices are 1Gig at the hub.
Cheers
Hi,
I checked my Core ethernet card connecting @ 1000
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 01)
Subsystem: Elitegroup Computer Systems RTL8111/8168 PCI Express Gigabit Ethernet controller
Kernel driver in use: r8169
Kernel modules: r8169
I checked my MD
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 03)
Subsystem: AOPEN Inc. Device 0706
Kernel driver in use: r8169
Kernel modules: r8169
So I don't think it would have anything to do with the r8169 driver.
On my Core I used ethtool eth0
Settings for eth0:

So on my MD

My MD is connected @ 100Mb/s and the link partner isn't showing 1000baseT as an option.
To see if the MD would connect at 1000Mb/s I tried...
ethtool -s eth0 speed 1000 duplex full autoneg on
The ethernet link to the MD drops (no lights or activity at each end).
I pulled out the ethernet cable on the MD and also powered it off. Reconnect and power up and it comes up @100Mb/s with terminal message Write failed: Broken pipe.
The spec's for the AOpen DE7000 says 10,100,1000.
Any ideas?
Cheers.
did you check the speed by copying a large file?
Hi posde,
I moved the MD into the switching hub area and hooked it up using a 6 foot Cat5 cable and voila - 1000Mbps.
So I need a new cable I guess.
Thanks.
