ALTQ + RELENG_8 + em(4) will not work at the moment. It does not matter what your PF ruleset looks like or how much traffic you are pushing. The packets that transit the em interface simply never make it to the ALTQ queues (not even the interface's root queue). Thus any kind of bandwidth rate limiting or whatever you are doing will not work. This was fixed by the following commit. I think its supposed to MFC soon? http://svn.freebsd.org/viewvc/base?view=revision&revision=203834 On Sat, Mar 6, 2010 at 12:21 PM, Jeremy Chadwick <freebsd@jdc.parodius.com>wrote: > > Why I care: upgrading our RELENG_7 machine which uses ALTQ directives is > on my to-do list, and if this feature is somehow broken under RELENG_8, > I need to know in advance so I can use ipfw + dummynet instead. > > -- > | Jeremy Chadwick jdc@parodius.com | > | Parodius Networking http://www.parodius.com/ | > | UNIX Systems Administrator Mountain View, CA, USA | > | Making life hard for others since 1977.
