Configure the Ethernet or aggregated Ethernet physical interface by including the encapsulation statement with the vlan-vci-ccc option at the [edit interfaces interface-name] hierarchy level:
- [edit interfaces interface-name]
- encapsulation vlan-vci-ccc;
When the encapsulation type vlan-vci-ccc is configured on the physical interface, all logical interfaces configured on the Ethernet interface must also have the encapsulation type set to vlan-vci-ccc.
