Thank's Alan, I have sent the info to a network guy here. However the problems show up sometimes, not always, SNAP packages are getting throw. The problem started shortly after we changed the hardware (new z196 boxes with new OSAcards) And it now seems they stopped after network/intranet maint this weekend. Hmm...
So for the moment we just wait and see, there is no error to trace right now. It looks promising so far, but we don't know why, and that is kind of disturbing. /Tore _________________________________________________ Tore Agblad System programmer, Volvo IT certified IT Architect Volvo Information Technology Infrastructure Mainframe Design & Development, Linux servers Dept 4352 DA1S SE-405 08, Gothenburg Sweden Telephone: +46-31-3233569 E-mail: [email protected] http://www.volvo.com/volvoit/global/en-gb/ -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Alan Altmark Sent: den 9 december 2011 04:18 To: [email protected] Subject: Re: IP snap packages problem anyone ?

If you can believe the OSA book, only OSE (LCS) chpids directly support 802.3 with 802.2 SNAP. I would expect layer 3 OSA connections on OSD chpids to discard the frames, as it supports only Ethernet II (DIX) and 802.3. In layer 2 mode, however, the frame is passed as-is (with SNAP headers) to the host. I don't know what the state of Linux's ethernet SNAP support is. The code in net/ethernet/eth.c that deals with (some of) this stuff looks a bit hazy to me. Dunno.
