    tc qdisc add dev eth0 root handle 1: cbq avpkt 1000 bandwidth 1000mbit

    Assign base rule for the 1000Mbit interface

    tc class add dev eth0 parent 1: classid 1:1 cbq rate 52mbit allot 1500 prio 5 bounded isolated

    Append class with limited bandwidth - 52Mbit

    tc filter add dev eth0 parent 1: protocol ip prio 16 u32 match ip dst match ip dport 1234 0xffff flowid 1:1
