[altq 1147] Newbie: Limit bandwidth on Openbsd 2.8 & altq 3.0

[Arild Jensen <arildjensen@yahoo.com>]

This is what I am trying to accomplish:

Limit all traffic to 800 kbit/s, except for our DMZ,
which can be accessed at 100 Mbit/s. I am running
OpenBSD 2.8 and Altq 3.0.

I've tried the following /etc/altq.conf file:

----------------------------------
interface fxp0 bandwidth 100M hfsc
class hfsc fxp0 def_class root pshare 100 default

class hfsc fxp0 int_class root grate 90000K
        filter fxp0 int_class 1.2.3.128
255.255.255.192 0 0 6
class hfsc fxp0 ext_class root grate 100K
        filter fxp0 ext_class 0 0 0 0 6
----------------------------------

but I get the following error:

----------------------------------
# /usr/local/sbin/altqd
altqd[11297]: ALTQ config file is /etc/altq.conf

altqd[11297]: tbr installed on fxp0 (rate:100.00M 
size:11.72K)

altqd[11297]: hfsc_class_parser: admission failure (no
bandwidth)

altqd[11297]: can't add class 'int_class' on interface
'fxp0'

altqd[11297]: Config failed. Exiting.
----------------------------------

I am new to Altq, and I realize I may be doing
something obviously wrong or stupid, but I just can't
see it. Any help would be greatly appreciated.

Thanks in advance!
