LARTC - May 2004 - Limit filters

it is posible to do more than 2048 filter rules and classes like this:
 

        /sbin/tc class add dev eth1 parent 1:15 classid 1:101 htb rate 1kbit
ceil 6128kbit prio 1 quantum 1500
        /sbin/tc filter add dev eth1 protocol ip pref 0 parent 1: u32 match ip
dst 10.10.24.17 flowid 1:101
        /sbin/tc qdisc add dev eth1 parent 1:101 handle 101: sfq



        /sbin/tc class add dev eth1 parent 1:15 classid 1:102 htb rate 1kbit
ceil 6128kbit prio 1 quantum 1500
        /sbin/tc filter add dev eth1 protocol ip pref 0 parent 1: u32 match ip
dst 10.6.40.42 flowid 1:102
        /sbin/tc qdisc add dev eth1 parent 1:102 handle 102: sfq


        /sbin/tc class add dev eth1 parent 1:15 classid 1:103 htb rate 1kbit
ceil 6128kbit prio 1 quantum 1500
        /sbin/tc filter add dev eth1 protocol ip pref 0 parent 1: u32 match ip
dst 10.6.84.37 flowid 1:103
        /sbin/tc qdisc add dev eth1 parent 1:103 handle 103: sfq


        /sbin/tc class add dev eth1 parent 1:15 classid 1:104 htb rate 1kbit
ceil 6128kbit prio 1 quantum 1500
        /sbin/tc filter add dev eth1 protocol ip pref 0 parent 1: u32 match ip
dst 10.4.206.47 flowid 1:104
        /sbin/tc qdisc add dev eth1 parent 1:104 handle 104: sfq

when i reach the 2048 number of the next inserted rule give a message :

RTNETLINK answers: File exists

Just wondering, do you know the numbers are hex?
