Binary package hint: iproute
Using this script to create shaper:
/sbin/tc qdisc del dev vlan2 root
/sbin/tc qdisc del dev vlan2 ingress
/sbin/tc qdisc add dev vlan2 root handle 1: htb default 20 r2q 1
/sbin/tc class add dev vlan2 parent 1: classid 1:10 htb rate 768kbit burst 2k
/sbin/tc class add dev vlan2 parent 1: classid 1:20 htb rate 384kbit burst 2k
/sbin/tc filter add dev vlan2 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.245.159/32 flowid 1:10
/sbin/tc filter add dev vlan2 protocol ip parent 1:0 prio 2 u32 match ip dst
192.168.0.20 flowid 1:20
/sbin/tc qdisc add dev vlan2 parent 1:10 handle 10: sfq perturb 10
/sbin/tc qdisc add dev vlan2 parent 1:20 handle 20: sfq perturb 10
/sbin/tc qdisc add dev vlan2 handle ffff: ingress
/sbin/tc filter add dev vlan2 parent ffff: protocol ip prio 50 u32 match ip src
192.168.245.159/32 match ip dst 0.0.0.0/0 police rate 315kbit burst 12k drop
flowid :1
Then show filters
/sbin/tc filter show dev vlan2
filter parent 1: protocol ip pref 1 u32
filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1
filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0
flowid 1:10
match c0a8f59f/ffffffff at 16
filter parent 1: protocol ip pref 2 u32
filter parent 1: protocol ip pref 2 u32 fh 801: ht divisor 1
filter parent 1: protocol ip pref 2 u32 fh 801::800 order 2048 key ht 801 bkt 0
flowid 1:20
match c0a80014/ffffffff at 16
Then deleting
/sbin/tc filter del dev vlan2 prio 2 handle 801:
/sbin/tc filter del dev vlan2 prio 1 handle 800:
1-3 seconds after this command bug happens:
