assuming you are after CBQ, there is a limit of 256 queues imposed right now. This is the #define CBQ_MAX_CLASSES 256 in /usr/src/sys/altq/altq_cbq.h from a quick glance over it I don't see what's stopping you to increase it, but I never tried. you have to make sure that ROOT_CLASS_HANDLE (value 0xfffffffe) and DEFAULT_CLASS_HANDLE (value 0xfffffffd) are > CBQ_MAX_CLASSES, but that is already an insanely high limit. i'd say "try it" ;-) -- Henning Brauer, BS Web Services, http://bsws.de [EMAIL PROTECTED] - [EMAIL PROTECTED] Unix is very simple, but it takes a genius to understand the simplicity.
