PPA Number = 4
Description = lan4 Hewlett-Packard 10/100 TX Half-Duplex TT = 1500
Type (value) = ethernet-csmacd(6)
MTU Size = 1500

in this Operation Status (value) = down(2) mean whether the lan is faulty...?

pls find the link loop output of this card

udmsh02: # linkloop -i lan4 0x0010837BAB95
Link connectivity to LAN station: 0x0010837BAB95
error: get_msg2 getmsg failed, errno = 4
-- FAILED

reads that timed out : 1


pls help me to findout whether the card is faulty or not

Thanks in abvance

HI,
Can you try reset on that Lancard.

# lanadmin
lan
ppa 1
reset

See if the operational status is UP now.
Also before that you can check for any looose connections or so.

Hope that helps.

Shalom,

Its may be a porblem with the network than the card. Looks like link has been lost. Standard checklist here:

Wiring
Switch
Switch port settings.

lanadmin shows half duplex which is quite unusual these days. Switch port settings for this card must be 100 BaseT manual full duplex.

Unless of course you are connected to a half duplex hub or something.

Lets elminate the card as an issue:

linkloop is a good test, but I've got a hard here in the house that fails linkloop and does everything else perfectly.

1) Ping the cards ip address. if that doesn't answer its game over.
2) Ping another NIC. It that works, you are fine but I doubt based on what I've seen test 2 will succeed.
3) ioscan -fnC lan
4) Use mstm/cstm or xstm to exercize the card . If it flunks, replace it.
5) Boot the system and re-test. Sometimes thats the only fix to a link failure but its posible the card and OS can't recover from the link failure.
6) Insure that the OS is patched as current as possible. Latest quarterly and networking patches, anything specific to this card.
I think that about covers it.

Operation Status (value) = down(2)
means that the card is not seeing the link signal from the other end, so the LINK light in the network card will also be dark.

Begin by checking the network cable: if someone has disconnected or damaged it, it could cause a situation like this. A failed or disabled network switch/hub port could also cause this.

If this does not solve the problem, then check if the card works with another (known good) network cable: if it works, the fault is in the cable.
