    Question Shape it baby on a bridge...


    Hello all.

    I'm having some weird problem setting up a Linux bridge as a shaper.

    Bridge setup:
    br0 -> eth0.412 & eth0.413

    Shaper:

    #!/bin/bash
    TC=/sbin/tc
    EBTABLES=/sbin/ebtables

    $TC qdisc add dev eth0.412 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 mpu 64
    $TC qdisc add dev eth0.413 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 mpu 64

    #1kbps download speed
    ${TC} class add dev eth0.412 parent 1:0 classid 1:1 cbq rate 1KBit allot 1514 prio 1 avpkt 1000 bounded weight 1KBit
    ${TC} filter add dev eth0.412 parent 1:0 protocol ip handle 1 fw flowid 1:1
    ${EBTABLES} -A FORWARD -p IPv4 --ip-destination 192.168.36.34 -d 00:0B:CD:F0:1A:97 -j mark --set-mark 1 --mark-target ACCEPT
    #1kbps upload speed
    ${TC} class add dev eth0.413 parent 1:0 classid 1:1 cbq rate 1KBit allot 1514 prio 1 avpkt 1000 bounded weight 1KBit
    ${TC} filter add dev eth0.413 parent 1:0 protocol ip handle 1 fw flowid 1:1
    ${EBTABLES} -A FORWARD -p IPv4 --ip-source 192.168.36.34 -s 00:0B:CD:F0:1A:97 -j mark --set-mark 1 --mark-target ACCEPT

    This script doesn't seem to do anything.

    Your ideas are greatly appreciated.
    Zerth.
