vlans

Hi All,

I'm trying to configure a vlan interface, to do this I'm using the following command "vconfig add eth0 20". I have my interface up and running, but when I test it using "ping -I eth0.20 192.168.1.1" and in other console use "tcpdump -i eth0.20" I can not see any tagged frame.

Somebody knows what could be the problem???

Thanks!
