Hi All During testing i found very strange thing. After applying even example shaper: http://linux-ip.net/tc/hfsc.en/ ------------- # Example from Figure 1. tc qdisc add dev eth0 root handle 1: hfsc tc class add dev eth0 parent 1: classid 1:1 hfsc sc rate 1000kbit ul rate 1000kbit tc class add dev eth0 parent 1:1 classid 1:10 hfsc sc rate 500kbit ul rate 1000kbit tc class add dev eth0 parent 1:1 classid 1:20 hfsc sc rate 500kbit ul rate 1000kbit tc class add dev eth0 parent 1:10 classid 1:11 hfsc sc umax 1500b dmax 53ms rate 400kbit ul rate 1000kbit tc class add dev eth0 parent 1:10 classid 1:12 hfsc sc umax 1500b dmax 30ms rate 100kbit ul rate 1000kbit --------------- I had all traffic on eth0 stopped. Tried on br0 - same result. Even ARP becoming non-functional.

In HTB if you dont specify default class, traffic just pass without "shaping". Is it possible to keep same behaviour on both disciplines? Probably just dropping all traffic not good idea, cause if user working on remote box by forgetting specifying default class or by mistake using incorrect class number he will loose access to the box, if same interface is used for tests on shaping and access. In same time it is good, and can show accurate results on shaping, without bypassing some "forgotten" traffic. But at least it must be same, IMHO, on HTB and HFSC. -- Denys Fedoryshchenko Technical Manager Virtual ISP S.A.L. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
