Hiya all,
Could someone clarify for me the purpose of the =0Abandwidth parameter when=
used with hfsc? Please consider my queue (512Kb=0A max upload through the =
ADSL line):
=A0altq on em1 bandwidth 500Kb =0Ahfsc queue { ack, dns, ssh, other }
=A0 queue ack=A0=A0=A0=A0=A0=A0=A0 bandwidth 95% =0Apriority 8 qlimit 500 h=
fsc (realtime=A0=A0 20%)
=A0 queue dns=A0=A0=A0=A0=A0=A0=A0 =0Abandwidth 95% priority 7 qlimit 500 h=
fsc (realtime=A0=A0=A0 5%)
=A0 queue =0Assh=A0=A0=A0=A0=A0=A0=A0 bandwidth 95% priority 6 qlimit 500 h=
fsc (realtime=A0=A0 20%) =0A{ssh_login, ssh_bulk}
=A0=A0 queue ssh_login bandwidth 95% priority 6 =0Aqlimit 500 hfsc
=A0=A0 queue ssh_bulk=A0 bandwidth 95% priority 5 qlimit =0A500 hfsc
=A0 queue other=A0=A0=A0=A0=A0 bandwidth 95% priority 5 qlimit 500 hfsc =0A=
(realtime=A0=A0 20% default)
My understanding was that "bandwidth =0Axx%" tells pf that the queue can on=
ly use xx% of the total parent queue =0Abandwidth and the various guides on=
the Internet say that it cannot go =0Aabove 100% which sort of makes sense=
. However what I want, for example, =0Ais the 'other' queue to get all the =
upload bandwidth as long as there is=0A no acks or ssh traffic in the queue=
. If I set bandwidth 20% for other, =0Awon't that mean that no matter what,=
the 'other' queue will only get a =0Amaximum of 20% of the bandwidth (even=
if there is no ssh traffic =0Awaiting?)
I think I haven't quite understood this properly but =0Aperhaps someone cou=
ld clarify it. I found a lot out from calomel.org's =0Aexcellent page but t=
hat's the only bit that confused me.
Thanks
