Q-in-Q tunneling

I am having a Cisco 2921 router having IOS c2900-universalk9-mz.SPA.151-4.M3.bin. In which i have installed the HWIC-4ESW module.

I need to configure q-in-q tunneling.

As it is given in the following cisco document that q-in-q tunneling is supported on this module. 
http://www.cisco.com/c/en/us/td/docs/routers/access/ISRG2/software/feature/guide/QinQ_L2PT.pdf

But when i enter into the interface it is not showing dot1q-tunnel mode.

This is the output from the router.

2921(config)#int f 0/0/0
2921(config-if)#switchport mode ?
  access  Set trunking mode to ACCESS unconditionally
  trunk   Set trunking mode to TRUNK unconditionally

Can anyone tell me why it is not showing dot1q-tunnel mode and what i have to do to configure this interface as a dot1q-tunnel interface?

Hi Mukesh,you should check

Hi Mukesh,

you should check that your ios version supports this feature. Check the config guide and release notes for your version, or use feature navigator cisco.com/go/fn 

also check if you need any license. As of ios 15.x some features need to be licensed

 

hope this helps
