Sarjerao — Mon, 30 May 2005 03:24:43 GMT

Hi,
We have nclass 4000 with 4 port nic.
Suddenly I seen all ports disabled and when i try to up interface immdialty system given message resource temporarlily unavailable. When I checked using sam, network is unconfigured state. So I reconfigured nic; but now i am unable to ping that port. Network side is ok. there is no any error in syslog.
As system is crtitical I can't restart the system, is there any way to reset this nic only.

Hi,

Pls. post "lanscan" output.
Do you see astrisk (*) mark in front of any of the interfaces? If yes, there may be some connection problem.

Hi Sarjerao,

What about netstat -in?

# netstat -in
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
lan0* 1500 10.216.168.0 10.216.169.133 303570 0 1103000 0 0
lo0 4136 127.0.0.0 127.0.0.1 586870 0 586870 0 0

If any of the lan cards has link issue, it will show an o/p similar to whay lan0 is showing here.

Regards

Hi

Startup lanadmin and do the followings:
lan
ppa (select ppa # of lan)
reset
quit

This will reset your Nic interface

reset with lanadmin as Andrew mentioned....

I tend to shy away from SAM when setting nics - better from the command line and vi'ing the driver files and/or netconf in /etc/rc.config.d

/sbin/init.d/net stop
followed by immediate
/sbin/init.d/net start

May help in this situation. It may disrupt certain network applications.
