Increase speed of NIC

Sachin Patel — Thu, 08 Nov 2001 13:50:54 GMT

We have c360, 11.00.
lanadmin o/p
Description = lan0 Hewlett-Packard 10/100 TX Full-Duplex Hw Rev 0. TT = 1500
Type (value) = ethernet-csmacd(6)
MTU Size = 1500
Speed = 100

/etc/rc.config.d/hpbase100conf looks like
HP_BASE100_INTERFACE_NAME[0]=lan0
HP_BASE100_STATION_ADDRESS[0]=0x001083352B12
HP_BASE100_SPEED[0]=100FD
#HP_BASE100_DUPLEX[0]=
HP_BASE100_INIT_ARGS="HP_BASE100_STATION_ADDRESS HP_BASE100_SPEED"

#lanadmin -S 1000000000 0
Old Speed = 100
Unable to change speed: errno = 22

What is the solution? May be NIC is bad?
I changed cable. I try good cable from good system. I try different port.
Note: This system was working good before. Nothing change(hardware/software).

The speed is already 100Mb, why do you
want to change it?? In some of the newer
versions of the card, the speed is displayed
as 100 and not 100000. HP wants
to make it easier for us. But apparently
some folks find it reassuring to see more Zeros ;-)

Hi Sachin,

Are you trying to increase the speed to 1Gbps on a 10/100 card.

Hope this helps.

I agree, looks to be at 100 to me.

You want to change it to 10?

It can't go to 1000.

Why do you think it is slow? More details are needed to solve your problem.

Sachin,

Don't you think you are specifying 1GB?.... The number of 0's???..

Try lanadmin -X 100FD 0

All of you guys are thinking in one direction.

I have four c360 with same hardware configuration and same software. rest of them shows me 1000000000. other are at full duplex too.
Only this one is at half duplex and 100.

I know that this is 10/100 tx and so I just want this to be 100Mbps.

What about the patch levels? IIRR, the
lanadmin command showing the more easier version of speed reading is due to a network patch.

From the output you posted:
<Type (value) = ethernet-csmacd(6)
MTU Size = 1500
Speed = 100 >>

It is already listed as "Full Duplex" and
with speed of 100. So, where is the need of changing it. ANother suggestion is
have a look at the lanadmin size and revison
on all the four systems
#ll `which lanadmin`
#what `which lanadmin`

have you tried configuring it from SAM and checking the sam log? It might be more informative. It's in Networking and Communications -> Network Interface Cards

Hi Sachin,

Try

lanadmin -X 100FD 0

Take a look at the thread below,

Hi All,
#lanadmin -x 0
Current Speed = 100 Half-Duplex Auto-Negotiation-ON

And it is not right.
#lanadmin -X 100FD 0 is not doing anything.

I am thinking to hook up new PCI NIC card.

rick jones — Thu, 08 Nov 2001 22:58:27 GMT

the speed should be displaye din bits per second, not megabits per second. that it is displayed in megabits per second implies that the system may be a rev or three behind on patches

Thanks All of you.
Problem resolve.

RajMan when you mention about patch It struck me that I have try everthing except patch. But nothing was changed. System has itself decrease speed while it was running, Anyway I install new september-2001 patch reboot the system it was still showing 100Half duplex run lanadmin -X 100FD and now system is at 100000000 speed. Reboot system one more time and it is Good.

rcp of 1MB file was taking hours takes only fraction of second.
