[altq 482] Something wrong with my CBQ configuration file ?

[=?big5?B?pP2utqZ0?= <aries@kungsrv.ee.ncku.edu.tw>]

Hi:

 

    I tried to use altq-2.2 on FreeBSD 3.4-STABLE, the experimental environment is depicted

following:

 

        Host A --------- Gateway B ---------- Host B

                             (^vr2)           (^vr1)

                                                  ^CBQ

 

/etc/altq.conf:

 

interface vr2 bandwidth 10M cbq
class cbq vr2 root_class NULL priority 0 admission none pbandwidth 100
class cbq vr2 unres_class root_class  priority 3 pbandwidth 60 default
class cbq vr2 res_class root_class priority 6 pbandwidth 40 admission cntlload

interface vr1 bandwidth 10M cbq
class cbq vr1 root_class NULL priority 0 admission none pbandwidth 100
class cbq vr1 unres_class root_class  priority 3 pbandwidth 60 default
class cbq vr1 res_class root_class priority 6 pbandwidth 40 admission cntlload

 

    Run altqd, then, I run MGEN to generate 8Mbps traffic from Host-A to Host-B.

I used ttt to monitor the traffic on Host-B, and I saw that Host-B received 8Mbps(

not expected 2Mbps(=10M*60%)) !!  Is there any error in my altq.conf?

 

    Another phenomenon, if I commanded "kldload altq_cbq" rather than "altqd",

Host-B will receive 8Mbps traffic no matter the percentage is in altq.conf.

 

    Any suggestion or instruction will be much appreciated!

 

 

Cheers,
