Lan card issue

[sree_5]

Hi all,

I have Three lan interface cards in my server.All the lan cards shows "UP" status when lanscan is run, but One of the card is not pingable from any other machines but is self pinging.Operational status is "DOWN" in lanadmin but shows the Administration status as "UP".I tried resetting the card, but of no use. Is this a h/w problem with the lan interface card ..? or is there any thing which I can do to make the interface up.
thanks in advance

HI,
I don't think it is H/w problem. It could be the configuration problem.
what does this shows you:
# ifconfig lan3
Assuming lan3 is your 3rd NIC.
IS it showing status as:
lan3: flags=843

Hi Bharath,
thanks for the reply.
The output of the ifconfig is as below:
lan2: flags=842

the interface is not showing"UP" in ifconfig output.

Hi,

you can try ifconfig lan up

Is there a cable attached and patched accordingly at your switch?
Is there an IP address assigned to it? (see /etc/rc.config.d/netconf)
If so, does it appear in the 'netstat -rn output' ?

Hi,

Maybe this 3rd LAN port is your LAN Console port. Pls find attached a useful doc that allow you configurate this port via GSP.

Rgds.

Hi all,

I have already tried making the interface "UP" using ifconfig lan2 up. but again of no use.
IP address is configured and is self pingable.

Hi,

It is not a console IP.
The ip address is very much there in netstat -rn and netstat -in outputs..

Hi sree,

With all your feedbacks
It just looks like the connectivity issue.
If possible can you try connecting other lan cable..
Or if the cable is good ..do you have the proper driver installed for that card..

Hi,
Yes as suggested by imran check your Patch Cord and the switch port. Try with working One.
If this still doesn't work then try reconfiguring the NIC card again.

# ifconfig lan2 down
# sam
Select Network Configuration
NIC configuration
Reset all configuration for lan2, disable it
Reconfigure all options again with correct entries (IP,Subnet,Gateway etc.), enable it
exit from SAM.

See now if it works.

Hi,

One more useful hint I forgot to mention is linkloop also throws out an error.
linkloop
error: get_msg2 getmsg failed, errno = 4
-- FAILED
frames sent : 1
frames received correctly : 0
reads that timed out : 1

Is this something which is useful..?

[sree_5]

Hi,

the output of the netstat -in shows a "*" mark near to lan2.. ( lan2* )..

Shree,
If linkloop throws error then you have one or more of the following issues:

1. Bad NIC
2. Bad Cable
3. Wrong Connectivity
4. Bad Switch Port

And now it comes to Hardware level.

Regards,

PS. NIC may not be bad since you told in earlier reply that you are able to do self ping. Check for the other options.

Hi Bharat,

I checked the cable and ports .. All physical cable connections seems to be Ok..

[Bharat Katkar]

Now i doubt it could be a Management Port.
To check go to GSP prompt thr' console:
GSP>ls
It will display the MAC address.. note it down and try doing linkloop to this address. If it shows OK then it is a LAN console and not your regular NIC card.

Can you explain which server model you are using and where that Lan port is.

post your
1. /etc/rc.config.d/netconf
2. lanscan
