Date: Thu, 12 Jun 1997 18:46:42 +0200 Organization: Universidad del Pais Vasco - Dpto. de Electricidad y Electronica Lines: 15 Message-ID: <33A027F2.41C67EA6@we.lc.ehu.es> NNTP-Posting-Host: tiburon.we.lc.ehu.es Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Mailer: Mozilla 3.01 (X11; I; FreeBSD 2.2.1-RELEASE i386) Xref: euryale.cc.adfa.oz.au comp.unix.bsd.freebsd.misc:42827 Curiously, "netstat -i" _always_ shows 0 collisions on the vx0 ethernet interface (3COM 590, FreeBSD 2.2.1). However, other hosts attached to the same (saturated) segment have about 5% collision rate. I suspect that the vx driver does not increment the collision counter. A colleague has another FreeBSD box with a 3C900 (also vx driver), and it also shows 0 collisions. Isn't surprising? --JM ------------------------------------------------------------------------ Jose M.
