Hi Gang, I'm still experiencing some bandwidth starvation with my script (below), so I decided to look at the statistics by using: tc -s qdisc show dev eth0 (where eth0 is the interface I'm trying to rate-limit outbound packets) I get, for example: qdisc sfq 21: quantum 1514b perturb 10sec Sent 133527926 bytes 413260 pkts (dropped 0, overlimits 0) qdisc sfq 20: quantum 1514b perturb 10sec Sent 42622473 bytes 184396 pkts (dropped 0, overlimits 0) qdisc htb 1: r2q 10 default 21 direct_packets_stat 0 Sent 176150399 bytes 597656 pkts (dropped 0, overlimits 137379) On first appearance, I would think this is telling me that the overall limiting is kicking in, and I'm not limiting specifically in the class 21 (which is where I want the limiting). Here's my script: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 21 tc class add dev eth0 parent 1: classid 1:1 htb rate 370kbit tc class add dev eth0 parent 1:1 classid 1:20 htb prio 0 rate 100kbit tc class add dev eth0 parent 1:1 classid 1:21 htb prio 1 rate 200kbit ceil 370kbit tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 10 tc qdisc add dev eth0 parent 1:21 handle 21: sfq perturb 10 # Set high priority for a certain destination IP address: tc filter add dev eth0 parent 1:0 protocol ip prio 0 u32 \ match ip dst 147.135.2.0/24 flowid 1:20 # Set high priority for <64 byte packets: tc filter add dev eth0 parent 1:0 protocol ip prio 0 u32 \ match ip protocol 6 0xff \ match u8 0x05 0x0f at 0 \ match u16 0x0000 0xffc0 at 2 \ match u8 0x10 0xff at 33 \ flowid 1:20 # Set high priority for ICMP packets: tc filter add dev eth0 parent 1:0 protocol ip prio 0 u32 \ match ip protocol 1 0xff \ flowid 1:20 # Set high priority for UDP packets (hopefully all VOIP!): tc filter add dev eth0 parent 1:0 protocol ip prio 0 u32 \ match ip protocol 17 0xff \ flowid 1:20 Am I reading this incorrectly?
