NIC up but not working...

[spoodie]

I'm a fairly accomplished UNIX sysadmin and I've got a real tricky problem. The NIC (on a V240) is up and configured but won't provide any service, also the link and activity light go out when the OS is booted into multiuser mode. The only thing I can see wrong is that RUNNING is missing from the ifconfig output:

hostname-# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000802<UP,BROADCAST,MULTICAST,IPv4> mtu 1500 index 2
inet 82.132.132.53 netmask fffffe00 broadcast 82.132.133.255
ether 0:3:ba:76:cb:d7
hostname-#

Any thoughts?

Thanks,

Is your NIC hardcoded to use 100MB Full Duplex?

Is your switch port set to Auto Negate or 100 FULL?

the NIC is in Status UP but not in Status RUNNING (like your loopback)

how did you configure this NIC? Can you post what you did?
(using ifconfig commands or just touch /etc/hostname.bge0)

Try unplumbing & replumb

I am trying to track down what might be a problem. When I run an IF config on the external interfaces do not have a "RUNNING" flag. I get this when I bring the interface "up", Let me explain.

ifconfig eri1 unplumb
ifconfig eri1 plumb
ifconfig eri1 63.85.160.57 netmask 255.255.255.0 broadcast 63.85.160.255 -trailers
ifconfig -a

eri1: flags=1000862<BROADCAST,NOTRAILERS,RUNNING,MULTICAST,IPv4> mtu 1500 index 8
inet 63.85.160.57 netmask ffffff00 broadcast 63.85.160.255
ether 0:3:ba:27:69:4

at this point the Interface looks fine ~ except that it is not "UP"

ifconfig eri1 up

eri1: flags=1000823<UP,BROADCAST,NOTRAILERS,MULTICAST,IPv4> mtu 1500 index 7
inet 63.85.160.57 netmask ffffff00 broadcast 63.85.160.255
ether 0:3:ba:27:69:4

Now the interface is UP but not RUNNING, any help would be most appreciated.

This problem has been sorted now by a colleague and with a little help from Sun. The problem was down to incompatible network speeds, the switch port was set to 100 full duplex and the server NIC was set to 10 full duplex by an rc script which I didn’t spot; S99nettune.

Thanks for you help though and I'm sure I would have cracked it myself with your help was I given the time.

Spoodie,
Thank you for the update, unfortunately for me this is not the answer for my problem. In an attempt to remove as many factor as possible from this mix I have remove the switch that the two systems are plugged into and connected them via across over cable. I then verified all NDD settings for this interface.

The problem remains and is reproduceable.

Thanks
