I have about 8000 ips in network. Each ip must be shaped to no more then 2Mbit/s. My configuration is: ipfw pipe 22 config bw 2Mbit/s mask dst-ip 0xffffffff buckets 8192 So, when the net.inet.ip.dummynet.hash_size: 64 [r...@vpn ~]# ipfw pipe 22 list 00022: 2.000 Mbit/s 0 ms burst 0 q131094 50 sl. 0 flows (1 buckets) sched 65558 weight 0 lmax 0 pri 0 droptail sched 65558 type FIFO flags 0x1 1024 buckets 4 active When: net.inet.ip.dummynet.hash_size: 8192 ipfw pipe 22 config bw 2Mbit/s mask dst-ip 0xffffffff buckets 8192 [r...@vpn ~]# ipfw pipe 22 list 00022: 2.000 Mbit/s 0 ms burst 0 q131094 50 sl. 0 flows (1 buckets) sched 65558 weight 0 lmax 0 pri 0 droptail sched 65558 type FIFO flags 0x1 1024 buckets 4 active When: net.inet.ip.dummynet.hash_size: 8192 ipfw pipe 22 config bw 2Mbit/s mask dst-ip 0xffffffff NOTE: I have not use "buckets" parameter [r...@vpn ~]# ipfw pipe 22 list 00022: 2.000 Mbit/s 0 ms burst 0 q131094 50 sl. 0 flows (1 buckets) sched 65558 weight 0 lmax 0 pri 0 droptail sched 65558 type FIFO flags 0x1 8192 buckets 4 active >How-To-Repeat: Please see full description >Fix: Do not use "buckets" parameter and set appropriate sysctl >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
