lanadmin command problem

[MQ'ski]

when I use command
lanadmin -S 100 it shows me menu like lanadmin -h
when type lanadmin it comes to tool.
How to change lan speed :(?

[Pete Randall]

Try:
lanadmin -X spd_duplex ppa#,

ie: lanadmin -X 100FD 1

Hi I did as you said but how to check it works...
lanadmin
lan
config
shows me still speed 10000000

but my ppa is 0...
this command is not supported

[MQ'ski]

I will give points to all my questions given since yesterday :P
because I have so much problems to solve and Im in hurry but I will do it today after 17:00
Chers ,)...
I must solve much problesm before 17:00

First, use lanscan to get the PPA#, i.e.
lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
10/16/8 0x080009DB2037 1 UP lan1 snap1 1 ETHER Yes 119
10/12/6 0x0060B006C443 0 UP lan0 snap0 2 ETHER Yes 119

There's two cards, the first is PPA# 0, the second is PPA# 1.

Then use lanadmin to set the appropriate PPA# to the speed desired.

[Pete Randall]

One other thought - from man lanadmin:
For operations other than display, you must have superuser privileges.

You are doing this as root, aren't you?

Pete

[Pete Randall]

Sorry, I got it backwards in my description of the lanscan output. The first card is PPA# 1 (identified by lan1), the second is PPA# 0 (lan0).

Pete

[MQ'ski]

ok. see.
I do lanscan:
Path Address In# State NamePPA ID Type Support Mjr#
0/0/0/0 0x00306E1C6101 0 UP lan0 snap0 1 ETHER Yes 119
0/2/0/0 0x00306E1E5D7A 1 UP lan1 snap1 2 ETHER Yes 119
then:
root@smi:/> lanadmin -s 0
Speed = 10000000
I would like to change for ex 100FD
root@smi:/> lanadmin -S 100 0
Old Speed = 10000000
Unable to change speed: errno = 22
root@smi:/>
or
root@smi:/> lanadmin -S 1 0
Old Speed = 10000000
New Speed = 10000000
So it means that I can not change the speed?

[Pete Randall]

What kind of hardware are we working with here? What's the server? What are the two network interface cards that we're seeing? It looks to me that you're trying to change the internal card (the one on the core I/O board) and I would expect that the additional card (lan1) is probably the 100MB capable card.

Pete

[MQ'ski]

Hi
It is L server.
Only lan0 is used to communicate.

[MQ'ski]

The question is... can we change speed on lan0?

===================================================================
lan 0 0/0/0/0 btlan3 CLAIMED INTERFACE HP PCI 10/100Base-TX Core
/dev/diag/lan0 /dev/ether0
lan 1 0/2/0/0 btlan5 CLAIMED INTERFACE HP A5230A/B5509BA PCI 10/100Base-TX Addon
/dev/diag/lan1 /dev/ether1 /dev/lan1

[Pete Randall]

I'm stumped - it certainly looks like you should be able to change speeds but I don't know why it won't work (other than the guess about not doing it as root).

Pete

[MQ'ski]

Im afraid but I have shown you all data from the system...
now lanadmin show 10000000...
its 10 Mbites/s.
I think I can change it to 100 am I right?

[James Beamish-White]

Have you tried configuring this through SAM?

Networking and Communications -> Network Interface Cards -> Actions - Configure?

Cheers!
James

[MQ'ski]

No...
with command

[MQ'ski]

I changed via sam... (usin X Client)
and connection closed. :(..
telnet doesnt work :(

[James Beamish-White]

Hmmm, maybe a hardware problem? I'd log a call with HP...

Sorry I can't be of more help.

James

[MQ'ski]

ok I brought back to 10 it works...

[Ron Kinner]

What is the other end of the Ethernet cable connected to? Does it support 100M? Has it been manually set to 10?

Ron

[MQ'ski]

good question!...
there are few network elements...
and are set to 10... but if are autonegotiating???
how it is possible to change all network elenets to diffrent speed and don't lose netework alive.

[Pete Randall]

And what about auto-negotiation? It should be off at both ends.

Pete

[MQ'ski]

if autonegotiation is off it means that nodes can have diffrent speed. if one node is 10 then another node which have 100 will be connecting with 10Mb node?

[Darrell Allen]

Hi,

I strongly suggest you set both ends of the connection to the speed you desire. This means you turn off auto-negiotiation. Auto-neg often fails to set both ends to the same speed and duplex setting. It often results in slow transfer rates however I've also experienced a connection that will drop once I changed the speed / duplex setting on the fly. It was simply a problem with auto-neg.

Set the switch port then set the server to the same setting.
