Source quench with HP UX rp7410 server 10/100 NIC

[Sandeep Geet]

I am having rp7410 server with HP UX 11i.

Sometimes I get source quench while accessing server.

Is some problem with network card?

How can I check card configuration and verify?

Can someone help?

Thanks in advance.

To check errors related to Network. You can use "nettladm -i " command. This logs the errors with network.

2:- This errors occurs when the remote machine transmits data to the HP-UX box at a fater rate. Try to put the speed of the card 100Mbps instead of auto negotiation.

Did you use 3COM switch ?
Do not set Auto in your network card

Also use NETSTAT and LANADMIN to get a erorr also check DMESG and /var/adm/syslog/syslog.log

Disable by this command
# ndd -set /dev/ip ip_send_source_quench 0

and verify that /etc/rc.config.d/nddconf file sees as follows

TRANSPORT_NAME[X]=ip
NDD_NAME[X]=ip_send_source_quench
NDD_VALUE[X]=0

"Source Quench" is explain in RFC1812 on Chapter 4.3.3.3:
