Shalom,

Things to check:

1) Networks and switches between machines
2) cstm/mstm/xstm exercize function on the target card.
3) See if the target machine is really busy.

Hi

Type to ping from your desktop & other unix server, what is the output you get. If you get the similar one then it will be a LAN.

Also check for you servers Lan config, (half or full duplex mode.)

Hi RobertDJ,

I have the same problme while I ping from my Cisco router to HPUX 11(i) version.

I saw at some other reply for similar question, it said it would be fixed hight version than 11.0

It seems it does not because I use higher version that 11.0

It is a bug or just the way it is?

I know I can set it as "0" to disable quenching, but I just want to make sure if sending quench is a normal way at HPUX.
