I don't understand the following: root@jmnrouter:~# tc -s class ls dev vlan1 && tc -s qdisc ls dev vlan1 class hfsc 1: root Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 0 level 2 class hfsc 1:1 parent 1: sc m1 0bit d 0us m2 220000bit ul m1 0bit d 0us m2 220000bit Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 31304 work 7533852 bytes level 1 class hfsc 1:10 parent 1:1 sc m1 1024bit d 8.0ms m2 100000bit ul m1 0bit d 0us m2 220000bit Sent 6892869 bytes 33300 pkts (dropped 0, overlimits 0) period 32750 work 6892869 bytes rtwork 6725586 bytes level 0 class hfsc 1:20 parent 1:1 sc m1 4096bit d 100.0ms m2 75000bit ul m1 0bit d 0us m2 220000bit Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 0 level 0 class hfsc 1:30 parent 1:1 sc m1 8200bit d 200.0ms m2 30000bit ul m1 0bit d 0us m2 220000bit Sent 640821 bytes 636 pkts (dropped 0, overlimits 0) period 277 work 640821 bytes rtwork 199829 bytes level 0 class hfsc 1:40 parent 1:1 sc m1 8200bit d 300.0ms m2 15008bit ul m1 0bit d 0us m2 220000bit Sent 162 bytes 3 pkts (dropped 0, overlimits 0) period 3 work 162 bytes rtwork 162 bytes level 0 qdisc hfsc 1: default 30 Sent 7537524 bytes 33953 pkts (dropped 6, overlimits 4145) backlog 3p Why is the qdisc backloged with dropped packets and overlimits when the classes are not? The txlen on the vlan1 device is 1000. This is happening with 256kbit up dsl with only one voip conversation utilizing the link (90kbit codec). The voice is occasionally gets choppy and I'm trying to figure out if it is due to the backlog or my setup etc? What tools are availabe to debug this stuff? Thanks for all of your insight and a VERY informative mailing list. _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
