Cord, you can use the same major numbers in diferent devices, no problem. You cannot have repeated minor numbers in the same device, but in diferent devices it is OK.
Note that sometimes using diferent major numbers may be a good idea, for example, when you are scripting this may help...

Hi,
the documentation says "[the major number of a class] must be unique
within a egress or ingress setup. The minor number must be unique within
a qdisc and his classes."
What is meant by "setup"? Does that include all qdiscs attached to any
network device? Ie, if I have a qdisc attached to eth0 and another
attached to eth1, do the major numbers I use have to be different at all
or could I use the same number structure in eth0 and eth1?
Short example to explain:
tc qdisc add dev eth0 root handle 1: htb default 13
tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps...
tc class add dev eth0 parent 1:1 classid 1:10 htb rate...
...
tc qdisc add dev eth1 root handle 1: htb default 13
tc class add dev eth1 parent 1: classid 1:1 htb rate 100kbps...
tc class add dev eth1 parent 1:1 classid 1:10 htb rate...
...
Is this valid? Or do I have to use "2:" instead of "1:" in the second part?
thanx cb
