Hello, I have a linux bridge setup and am using HTB to bandwidth manage traffic passing through the bridge. I want to manage "some" of the traffic passing through the bridge. I figured I can do this if I dont define a "default" class on the qdisc. I will only config classes for traffic I want to manage. Assume that i Have traffic for network 10.0.0.0/24 passing through the bridge. I only want to manage traffic for network 10.0.0.0/29 and 10.0.0.8/29 and not manage the rest of the traffic for the /24 Here is my script: ###START OF SCRIPT### #create the qdisc tc qdisc add dev eth1 root handle 1: htb default 30 tc class add dev eth1 parent 1: classid 1:1 htb rate 608kbit ceil 608kbit prio 1 #create class for 10.0.0.0/29 tc class add dev eth1 parent 1:1 classid 1:10 htb rate 256kbit ceil \ 608kbit prio 3 tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip \ dst 10.0.0.0/29 flowid 1:10 tc qdisc add dev eth1 parent 1:10 handle 10: sfq perturb 10 #create class for 10.0.0.8/29 tc class add dev eth1 parent 1:1 classid 1:20 htb rate 352kbit ceil \ 608kbit prio 3 tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip \ dst 10.0.0.8/29 flowid 1:20 tc qdisc add dev eth1 parent 1:20 handle 20: sfq perturb 10 ##Default class is commented #Create default class #$CLASS 1:30 htb rate 300kbit ceil 300kbit prio 1 #$QUEUE 1:30 handle 30: sfq perturb 10 ##END of SCRIPT## Ran the script with no errors. Will i be able to achieve setup that I want? How will htb traffic no being classified since there is no default class? Thanks. Paul P.
