Cannot See New LAN Card IP

Bruce Jackson — Sat, 29 Sep 2001 11:33:36 GMT

Hi All,

I installed a J3514A LAN Card into a K370 this morning and have installed the driver and configured it successfully through the Network section of SAM.

lanscan shows it's enabled and ifconfig shows it's up, and has the right IP address. But pinging from another machine on the network doesn't reach it. I can readch the other network address of this machine OK and both are plugged in the same hub. The LAN card has a link light at the back, and I've tried swapping the cables so I don't think there's a problem there.

I think I'm missing a step in the config somewhere, but I don't know what it is.

TIA,

Bruce.

Hi Bruce,

A tool which comes handy in such situation is "linkloop" which verifies Lan connectivity at link level. (man linkloop)

Did you try lanadmin?

Are both your NIC configured in the same subnet? can you ping the new IP from the local machine? can you ping an external machine? If you have configured the new NIC for a different network, did you configure the routing tables (netstat -nr)?

Hi Ramesh,

I tried linkloop lan1 (the new nic): "Failed. Address has bad format".
I also tried lanadmin, but I didn't understand it.

Then I tried forcing the transfer rate by adding 100fd to the hp_base100_speed in the /etc/rc.config.d/hpgsc100conf.
That seemed to work OK, we can now ping in and out successfully!

Thanks a lot for your help!

Cheers,

Bruce

to use linkloop you need to supply the MAC address.

do a lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/0/0/0 0x00108327A70C 0 UP lan0 snap0 1 ETHER Yes 119
0/12/0/0 0x0060B0B3CD13 3 UP lan3 snap3 2 ETHER Yes 119

# linkloop 0x00108327A70C
Link connectivity to LAN station: 0x00108327A70C
-- OK

Hi Bruce,

Can you post your ioscan output. If you can post the complete ioscna output (ioscan -fn), it will be good, else post the one pertaining to the lan (ioscan -fnC lan).

thanks
