I'm afraid MUX-UNI doesn't give you local switching. For EoMPLS Port
Mode we use a local cable between two ports, configured like this:

interface GigabitEthernet1/1
 description EoMPLS test
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport nonegotiate
 mtu 9216
 no ip address
 udld port
!
interface GigabitEthernet1/2
 description EoMPLS port to other side
 mtu 9216
 no ip address
 no cdp enable
 xconnect 10.0.0.1 10 encapsulation mpls
!

The other PE is 10.0.0.1 and the "10" is a VC ID, so you can run several
VCs between boxen. We use SFP ports for this, but TX should do just as
fine. The configuration is mirrored on the other side.
