Ethernet adaptor configuration - Full duplex mode

dobso — Tue, 12 Apr 2005 12:05:50 GMT

Hi all,

I have just one question, I have to change configuration of some eth. interfaces to full-duplex 100M, autonegotiation = off;

i did it :

lanadmin -X 100fd 0

but this settings will be flushed during the reboot. I checked files /etc/rc.config.d/hpbtlanconf & hpetherconf, but all lines are commented.

Where I may find the proper config file ?
This is not my machine, I am only support person.

Many thanks for your reply.

Best regards,

dobso

The correct file depends on the driver for your card - use ioscan to check the driver then match it to this list:

btlan hpbtlanconf
btlan0 hpeisabtconf
btlan1 hpbasetconf
btlan3 hpbase100conf
btlan4 hpgsc100conf
btlan5 hppci100conf
btlan6 hpsppci100conf

Hi, many thanks for your reply. Can you please take a look on this ioscan whole output:

(/etc/rc.config.d)(root)#ioscan -fnClan

what about 'igelan'?

That means lan0 is a gigabit interface and the config file will be /etc/rc.config.d/hpigelanconf. In this case you want to set it to auto-negotiate if you are connnected to a Gb switch port.

Unless you know your switches are FUBAR, and have no hope of replacing them, it would be best to leave things on autoneg on both sides. While there have been historical issues with autonet on 100Base-T, when you want to start operating interfaces at gigabit speeds, autoneg is _required_ for gigabit speed.

FWIW, hard-coded on one end, and autoneg on the other is _not_ a valid configuration.
