What do these messages mean? Is this a hardware problem or a problem with the switch? And and all help would be appreciated. Thanks in advance.

your btlan4 is trying AutoNegotiation on your switch to select speed. As your switch obviously doesn't support this, change params of lan to fixed values

Hi John:

It looks like your network switch was down/reset for a little while or someone was pulling unplugging cables at the patch panel.

Your hub/router was shutoff or rebooted, unless someone was fast enough to remove all of your network cables at once. Notice that they came backup 30 seconds later.

Yes, it looks like the switch/hub was down for a bit.

Also, you should turn off autonegotiation on your btlan4 or you will have unpredictable behavior.

Edit /etc/rc.config.d/hpgsc100conf
Make sure it has these lines: (change lan1 to whatever your interface is)

HP_GSC100_INTERFACE_NAME[0]=lan1 HP_GSC100_SPEED[0]=100FD

Next time you reboot the settings will be fixed. Otherwise you can use lanadmin to set them now manually.

Hi John,

On your switch, set the port to 100MBPS, Full duplex, Fixed, Auto-Neg off.

Hope this helps.

Thanks

John,

I never had good time with Auto-Negotiation.It's better to turn-off Autonegotiation on both switch and on the system. SOmething might have happened to your switch port that caused the Augonegotiation errors.

Looks like someone did a manual setting of lan card with lanadmin command and hence the "11 secs" message.

Turn-off Autonegotiation on switch and the server and set them to 100MBPS FUll Duplex.
