Recently I came to know that, Without any options fw classifier maps
fwmark to classid.
tc filter add dev <iface> parent <qhandle> protocol ip prio 1 fw
i.e. if my packet has mark(0x10001) and class id is not set, then
above tc filter, will set class id = 0x10001 i.e. 1:1
But when I am trying it out, its not working! I am having class 1:1
defined but its not at all hit.
Am I missing something out here?
Seems to be broken, below is a paste from a mail I sent to this list 2
years ago showing it working. The same test now (apart from I am using
eth2 instead of eth0) doesn't work.
tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:a htb rate 1mbit
tc class add dev eth0 parent 1: classid 1:b htb rate 1mbit
tc class add dev eth0 parent 1: classid 1:c htb rate 1mbit
tc filter add dev eth0 parent 1:0 protocol ip fw
