I have installed a 1000Mbps NIC in my system. This is the system some of |
| 2 |
you read about me where I was trying to swap the names of eth0 and eth1 |
| 3 |
so maybe that has something to do with my problem. |
| 4 |
|
| 5 |
The light on the NIC shows 1000Mbps link, as does the switch it is |
| 6 |
connected to. Kernel messages show the link as autonegotiated, and |
| 7 |
1000Mbps. |
| 8 |
|
| 9 |
The only odd one out is mii-tool which claims "eth0: negotiated |
| 10 |
100baseTx-FD, link ok" |
| 11 |
|
| 12 |
I also tried using ethtool to set it at 1000Mbps anyway via ethtool -s |
| 13 |
eth0 speed 1000 , and the kernel again spits out messages about a |
| 14 |
1000Mbps link being up just fine. mii-tool still says the same as above, |
| 15 |
however. |
| 16 |
|
| 17 |
The problem is that I get speeds just as if it were a 100Mbps link, |
| 18 |
starting at about 9MB/s then dropping to about 8. |
| 19 |
|

As noted above I had two NIC's. One was an onboard 100Mbps, and the |
| 21 |
second an add on 64-bit 1000Mbps. I had to do some tweaking with nameif |
| 22 |
to get the 1000Mbps as eth0, and the 100Mbps as eth1. The reasons why I |
| 23 |
wanted this really don't matter. |
| 24 |
|
| 25 |
Making things more confusing, last night when I first applied the nameif |
| 26 |
changes, I DID see 1000Mbps speed transfers. |
| 27 |
|
| 28 |
I saw exactly this behavior in the past, what was happening was the |
| 29 |
traffic was going right back out the 100Mbps and thus we had 100Mbps |
| 30 |
speeds. However this time I've disabled the 100Mbps, even unplugged it. |
| 31 |
|
| 32 |
There are no unusual routing entries. I am not using iptables. |
| 33 |
|
| 34 |
I'm stumped here, any ideas? |
