Why is Operation State Down in lanadmin

Tony Williams — Tue, 12 Feb 2008 21:45:25 GMT

Anyone know why my NIC would have a Operation State "Down" in lanadmin, but ifconfig says its up, there are no EMS messages, nettl entries, dmesg's, syslog entries? The card is down it can't ping the switch port is good, cable good.

lanadmin -g mibstats 6

LAN INTERFACE STATUS DISPLAY
Tue , Feb 12,2008 15:42:56

PPA Number = 6
Description = lan6 HP PCI-X 10GBase-SR Release B.11.23.06
Type (value) = ethernet-csmacd(6)
MTU Size = 1500
Speed = 10000000000
Station Address = 0x000cfc001152
Administration Status (value) = up(1)
Operation Status (value) = down(2)

Thanks

This status:
Operation Status (value) = down(2)
means that the card is not seeing the link from the other side.

Check network cable for unplug, damage or switch,port for incorrect settings.

Thanks for the reply. I think I asked the wrong question. We are pretty sure we have a bad NIC, that's the problem. What I would like to know is why is lanadmin the only source that knew the NIC is Down? All other sources, ifconfig, nettl, EMS, all reported no status or that the NIC is up.

My opinion.
lanadmin looks at the hardware status.. ifconfig looks at the stack/software level.

Thanks the reason I ask is that we have many monitors that look at NICs, i.e. home grown scripts, OS SPI from OV Operations. Everything missed this event. A script I wrote checks ifconfig for its status. When I tested the script ifconfig went down when you unplug the NIC. So of course I thought I was covered.
