You ned to make sure you have 8021q module loaded

# modprobe 8021q

Then use vconfig to attach 802.1q tags to ethernet frames

# vconfig add ethx 20

(x is a index of ethernet interface card)

This will create the interface ethx.20 (the naming can be change with 
set_name_type option of vconfig, check the manual) wich is similar to a 
cisco subinterface with encapsulation dot1q 20. You can add ip with 
ifconfig, or do everything else you you with a network interface in linux.
