It ping for 5 mins and immedly gives source quench recieved.pls note that the switch is 100mbps full duplex,with auto negotiate disable.

Hi Krege,

Thanx for the information. but the problem is at the time of giving source quench error my network goes down for maore than 5 mins.And the same card is working without any problem in 10mbps 1/2 duplex without any problem...

what is the reason pls also let me know whether j3515A lan board will support 100mbps full duplex

thanx in advance

Your lan interface provides full auto-negotiation capabilities to select full or half duplex for 100mbps or 10mbps connections. So, yes, J3515A does support it.

You should verify that your switch is really set to 100mbs full duplex. Also check whether the length of the segments is over acceptable parameters for 10/100BaseTX, max. is 100m cable and 2 nodes per segment.

You might also want to try the latest btlan4 driver patch PHNE_22461 (+ dependent patches!). It provides some interesting fixes, e.g.

"The actual link configuration does not reflect what is manually configured in /etc/rc.config.d/hpgsc100conf."

"100BT card receive engine hangs resulting in discard of all incoming packets."

Good luck: Carsten

is the ip you are pinging an HP system too ???
The message means that IP you are pinging has a buffer full situation, that's being transmitted back to the source.
if the system u are pinging is HP then use ndd to turn off the messages.
ndd set /dev/ip ip_send_source_quench 0
This might affect certain applications which use the network extensively. So understand the consequences before you do this.
