You can also use hybrid mode for ports that need to support access (SAP) interfaces and network functionality.<br>

Hi,<br>
<br>
You need to config interface in "/configure router" context and set port to "ethernet network" mode instead of "access mode". Mpls is not supported on service (access) interfaces.<br>
