RHEL4 - NIC bonding - Wrong speed

Allan Andersen_2 — Tue, 10 Jan 2006 03:53:35 GMT

Hi everybody

I'm trying to get nic bonding to work on a dl 360 g4p with bcm5700. The bonding works, but i can only get 100 Mbit from each nic.

dmesg:

eth0: Using PCI INTX interrupt

Hi
You can try setting up the speed with mii-tool.

Hope that works

Cheers

isn't that tool replaced by ethtool? And also it doesn't support gigabit

I have seen that tread before. But unable to find a solution in it?

Re: RHEL4 - NIC bonding - Wrong speed

Ivan Ferreira — Tue, 10 Jan 2006 08:10:55 GMT

But ethtool reports

Speed: 1000Mb/s
Duplex: Full

Can you verify the speed on the switch? Do you have any output errors?

Re: RHEL4 - NIC bonding - Wrong speed

Allan Andersen_2 — Tue, 10 Jan 2006 08:16:49 GMT

yes ethtool reports says 1 Gb. But when they are bonded dmesg says they are forced to 100Mbit

I have done a troughput test where i had 2 Gbit in the other end and i was only able to transfer 7-8 MB/s

It seems to be some bug in linux bonding code. In bond_main.c I see a code which should get ethX speed/duplex status using ethtool API, but default value is 100MB.
So for some reason (or bugs in bonding code, or some interoperability issues with bcm5700 driver) bonding program cannot detect that eth0 work 1GB...
Do you use the latest RHEL4 update?

/etc/modprobe.conf

??

alias bond0 bonding
options bond0 miimon=200 mode=active-backup
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptscsih
alias scsi_hostadapter2 ata_piix
alias usb-controller ehci-hcd

What does yours say?

Are you using tg3 or bcm5700 drivers?

i'm so sorry but i have figured out the problem and it had nothing to do with the error in kernel log.

The server is on another vlan than the client testing from and therefore had to go trough another city(Max 155 MBit) I have tested with a server connected to the same vlan at 1 Gbit and was able to transfer with 40 MB/s so i assume it's working and the error in the kernel log just got me to look in the worng place.

I glad you found your problem and corrected it.

I urge you to assign points to other peoples responses in this question thread.

It encourages further response.

If you feel the response had no value, such as my two, assign zero.
