Hi My Os is Red Hat 6.2 server kernel 2.6.32 I set an ingress filter for a 1Gb ethernet interface, script: DEV=eth1 IP=xx.xx.xx.xx RATE=50mbps BURST=5m MTU=1mb tc qdisc del dev $DEV ingress tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: \ protocol ip prio 20 \ u32 match ip src $IP/32 \ police rate $RATE burst $BURST mtu $MTU \ drop flowid :1 I'm not getting a 50mbps band, it be 200kbps ~ 18mbps according <burst, mtu> value I set. After I run the script several times, I find the egress bandwith has been limited to 30mbps. qdisc on eth1: tc -s qdisc show dev eth1 qdisc mq 0: root Sent 13862277239 bytes 2746355 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 qdisc ingress ffff: parent ffff:fff1 ---------------- Sent 1372858005 bytes 176228 pkt (dropped 1539, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 ingress filter: tc -s filter show dev eth1 parent ffff: filter protocol ip pref 20 u32 filter protocol ip pref 20 u32 fh 800: ht divisor 1 filter protocol ip pref 20 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid :1 (rule hit 174518 success 173742) match c0a8017c/ffffffff at 12 (success 173742 ) police 0x18 rate 400000Kbit burst 5Mb mtu 1Mb action drop overhead 0b ref 1 bind 1 Sent 1372696737 bytes 173742 pkts (dropped 1539, overlimits 1539) restart network, and run the script, the egress bandwith is correct (about 100mbps). After run script 2~3 times, the egress bandwith again limit to less than 30mbps (depends on RATE in ingress filter) who can tell how to avoid this happened, and how to get the <burst,mtu> value to get the rate I want (50mbps) -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
