I am on SUSE, and able to configure dot1q(single tag) for an interface. How can I configure double tagging on an interface?

It's easy to add next level of dot1q tagging to an interface manually - using the vconfig utility.
Add a dot1q tag to interface:
vconfig add eth0 34
After this you will have a eth0.34 interface.
vconfig add eth0.34 56
This creates the eth0.34.56
See "man vconfig" for more detailed explanation.
To make the configuration permanent you need to use the configuration files in
I'm not sure how it's done in SUSE but in case of redhat you would create a file
with the following content:
DEVICE=eth3.161.34 ONBOOT=yes BOOTPROTO="static" USERCTL=no VLAN="yes" IPADDR="XXX.XXX.XXX.XXX" NETMASK="XXX.XXX.XXX.XXX"
