Hi,
I have a default class for my un-marked traffic
(prio 5) and a prio 0 class for the important stuff,
but I do not understand why my download traffic
is duplicated in both.
It work fine for my upload traffic (same setting
except the red class but I have the same
result if I create an esfq instead).
Any comments/information will be
appreciated.
Below my config :
tc commands from my scirpt :
# TC on my download link
tcdownload () { tc qdisc add dev $TC_D_INT root handle 1: htb default 99 debug $HTB_DEBUG tc class add dev $TC_D_INT parent 1: classid 1:1 htb rate ${D_LIMIT}kbit # VOIP
class have the highest priority
tc class add dev $TC_D_INT parent 1:1 classid 1:10 htb \ rate ${VOIP}kbit ceil ${D_LIMIT}kbit prio 0 tc qdisc add dev $TC_D_INT parent 1:10 handle 10: esfq perturb 10 hash dst limit 8 tc filter add dev $TC_D_INT parent 1: prio 0 protocol ip handle 10 fw flowid 1:10 # shape
everything at $D_LIMIT minus
$VOIP speed
tc class add dev $TC_D_INT parent 1: classid 1:2 htb \ rate $[$D_LIMIT-$VOIP]kbit ceil ${D_LIMIT}kbit # high
prio class 1:20 to low prio class 1:99
(default)
tc class add dev $TC_D_INT parent 1:2 classid 1:20 htb rate $[D_LIMIT-$VOIP]kbit prio 1 tc class add dev $TC_D_INT parent 1:2 classid 1:99 htb rate $[D_LIMIT-$VOIP]kbit prio 5 # all
