I'm trying to determine a class which would be used as default for new IP's on my network, here's my current setup:
# Delete qdisc rule
tc qdisc del dev br-lan root
# Add qdisc rule
tc qdisc add dev br-lan root handle 1: htb default 10
# Setup parent class
tc class add dev br-lan parent 1: classid 1:1 htb rate 2000kbit ceil 2000kbit
# Add child classes of parent class 1:
#Wired
tc class add dev br-lan parent 1:1 classid 1:10 htb rate 2000kbit ceil 2000kbit
#Wired2
tc class add dev br-lan parent 1:1 classid 1:11 htb rate 1000kbit ceil 1000kbit
#Wireless1
tc class add dev br-lan parent 1:1 classid 1:12 htb rate 250kbit ceil 150kbit
# Create packet filter rule using parent 1: class, matching to IP (src = outbound traffic, dst = inbound traffic)
# and assigning child class rule via flowid
tc -s filter show dev br-lan
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip src 192.168.1.35 flowid 1:10
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip dst 192.168.1.35 flowid 1:10
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip src 192.168.1.67 flowid 1:11
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip dst 192.168.1.67 flowid 1:11
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip src 192.168.1.104 flowid 1:12
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip dst 192.168.1.104 flowid 1:12
tc filter add dev br-lan parent 1: protocol ip prio 1 u32 match ip dst 192.168.1.104 flowid 1:12
In an ideal world, the default class would be class id 1:12, as shown above, allowing 250kbit bandwidth.
At the moment, any unrecognized device uses the parent class:
tc class add dev br-lan parent 1: classid 1:1 htb rate 2000kbit ceil
Which means they have the ability of taking the entire bandwidth of the network.
I've tried to study the following article: http://lartc.org/howto/lartc.qdisc.classful.html
However, I'm struggling to implement 'leaf classes', could anyone shed some light into this situation? Thanks
