so far we've not seen anything unusual via nettool. we did see something
interesting yesterday once we put a sniffer on. we were pinging from one of
the two 'problem' mpe systems to the router. the ping (from the 3000) would
eventually stall yet on the sniffer you could see that packets were still
being received and answered. in the words of our sr. network engineer: 'it
appears that LAYER 2 (MAC) communications continues until the target number of
frames has been transmitted. At the application layer, communications is lost
and the total send/receive count is under reported.' - d 'off to
call hp'
