[altq 565] Running ALTQ

["Andriy Korud" <akorud@polynet.lviv.ua>]

Hello all,

I've successfully compiled KAME cvsup, everything is working fine, but
when I try to run altqd with the following cfg file (very simple, just
for test):

interface dc0 bandwidth 100M cbq
class cbq dc0 root_class NULL priority 0 admission none pbandwidth 100
class cbq dc0 def_class root_class borrow pbandwidth 95 default 
#
class cbq dc0 tcp_class0 def_class pbandwidth 1
        filter dc0 tcp_class0 0 0 0 0 6

I got the following output:

Please note the error. And there is no limit - interface is working on
full speed.
Any ideas/suggestions?
