Online configuration of NIC possible?

[Ralph Grothe]

Hi,

simple question,
because of suspected idiosyncrasies between NIC and switch port setup, which cause prohibitively long lasting backups, I would like to reconfigure the NIC online, without impairing established sockets.
Currently the NIC is configured to auto-negotiate in half duplex mode.
I wish to toggle the Autoneg setting to "off" and set Duplex Mode to "full".
Can I do this without cutting off all pending connections?

Regards
Ralph

Hi,

with lanadmin -X 100FD you could set the interface online BUT this makes the interface unavaible for app. 11 seconds which can result in some breaks.

On some systems the syntax is:

# lanadmin -X 0 100FD

Make sure that you update the appropriate file in /etc/rc.config.d/hp..... for your type of card. You can do in 'sam' as well. There is a short delay whilst the card resets, but no current connections will be lost.
