The vlan-type dot1q can only bind one VLAN under a specific sub-interface, while dot1q termination could bind different VLANs on the same sub-interface with multi implements.
Also, vlan-type dot1q could be excuted directly under the sub-interface view, while the encapsulation dot1q-termination is required before the dot1q termination be implemented under the sub-interface view.
For a dot1q termination sub-interface, the router wouldn’t send ARP packets by default, command arp broadcast enable is required to enable the ARP broadcast, while it’s unnecessary for vlan-type dot1q.
