Yeah, the percentages in link-sharing are calculated against the
physical interface, but bandwidth is against the parent queue
(usually).
Here's my working sample, which does not make any great sense either.
I had just started playing with upperlimit, which should be settable
on multiple queues.
# backbone queueing
altq on em0 hfsc bandwidth 100Mb queue { q_em0_high, q_em0_high_bulk,
q_em0_med, q_em0_med_bulk, q_em0_low, q_em0_low_bulk }
queue q_em0_high bandwidth 10% hfsc(linkshare 1%) priority 7
queue q_em0_high_bulk bandwidth 40% hfsc(linkshare 4%) priority 6
queue q_em0_med bandwidth 10% hfsc(linkshare 1%) priority 5
queue q_em0_med_bulk bandwidth 20% hfsc(linkshare 2%) priority 4
queue q_em0_low bandwidth 10% hfsc(linkshare 1%) priority 1
queue q_em0_low_bulk bandwidth 10% hfsc(linkshare 1% default) priority 0
# vlan trunk queueing
altq on em1 hfsc(ecn upperlimit 500Mb) queue { q_cust, q_dmz }
queue q_cust hfsc(ecn realtime 2Mb upperlimit 40Mb ) \
{ q_cust_h, q_cust_hb, q_cust_m, q_cust_mb, q_cust_l, q_cust_lb }
queue q_cust_h bandwidth 10% hfsc(linkshare 1%) priority 5
queue q_cust_hb bandwidth 40% hfsc(linkshare 4%) priority 4
queue q_cust_m bandwidth 10% hfsc(linkshare 1%) priority 4
queue q_cust_mb bandwidth 20% hfsc(linkshare 2%) priority 2
queue q_cust_l bandwidth 10% hfsc(linkshare 1%) priority 1
queue q_cust_lb bandwidth 5% hfsc(linkshare 1% default) priority 0
queue q_dmz hfsc(ecn realtime 50Mb upperlimit 90Mb) \
{ q_dmz_h, q_dmz_hb, q_dmz_l, q_dmz_lb }
queue q_dmz_h bandwidth 10% hfsc(linkshare 5%) priority 7
queue q_dmz_hb bandwidth 40% hfsc(linkshare 10%) priority 4
queue q_dmz_l bandwidth 10% hfsc(linkshare 2%) priority 3
queue q_dmz_lb bandwidth 20% hfsc(linkshare 5% ) priority 0
