[LARTC] ip alias question

[Gilles Dégottex]

Hi all

	Sorry if i didnt found the answer in HOWTO's, mailing lists archives or any 
other place. and sorry if i write english like a spanish cow :P

	I'm currently using 'tc' to limit upload and stop breaking the connection of 
my cable modem. my eth0 has an ip alias eth0:1 which should not be limited by 
tc, but "tc qdisc add dev eth0" seems apply effect to eth0 AND eth0:1 :(
	Is there any smooth solution to leave eth0:1 in peace ? or do i have to limit 
effect with "ip src" and "ip dst" ?

Regards,
Gilles Dégottex

AFAIK, tc works on physical device queues. Thus having virtual devices
over the same physical interface will not let the virtual devices be
freed of control. You must use src/dst options. Instead of attaching to
virtual devices, it might be better to do it using subnets whereby you
do not have to give too many rules for matching src/dst ips.

I had "match ip dst <net ip>" for dowload filters and "match ip src <net ip>" 
for upload filters and everything works fine now !

thx
