On a Multiprise 3000 , ethenet adapter, what are the best tools to debug ping times that approach 100MS from a terminal. Doesn't matter which way, the traffic is going. If i go to the mainframe adapter, it reaches 100MS. Something bad wrong. TIA,

Often menas it is set to auto-negotiate but not doing it right--gets the duplex wrong. Or both ends hard set but set differently.

Thanks for you input. But i am confused. I assume you mean I can configure the ethernet adapter has FUll, half or auto-neg, correct? On the mainframe side, where does that get changed in the IP definitions? Why wouldn't I always want Full? WP

You don't say what operating system that Multiprise 3000 is running. If it's VM/ESA, then TRSOURCE TYPE IO is probably the best tool. A sniffer might be helpful regardless of the operating system, but only to narrow down where the problem is. A TCP/IP stack trace could be useful if that is where the problem seems to be.

I also find tracerte handy in these cases...can show problem routers (if you've more than one in the link, as we sometimes do). Being a bit of a debugging newbie, can someone say if I'm wasting my time? cheers Peter Bishop I.Solutions Delivery - Asia Pacific EDS Australia 36-46 George St Burwood NSW 2134 Australia * +61 2 9378 0113 * peter.bishop@eds.com > -----Original Message----- > From: Walter Pyle [SMTP:Phw1443@AOL.COM] > Sent: Wednesday, December 13, 2000 4:57 AM > To: IBMTCP-L@VM.MARIST.EDU > Subject: PING times > > On a Multiprise 3000 , ethenet adapter, what are the best tools to debug > ping > times that approach 100MS from a terminal.
