In a normal configuration, ports configured as EVLAN internal and external ports do not allow regular VLAN traffic to be carried. However, in some configurations, it would be desirable to allow both regular VLAN and EVLAN traffic on a given port. Such ports would function as internal or external ports for EVLAN traffic, and would function as they usually would. In addition, these ports function as a trunk port for regular VLANs. To enable this, the regular VLAN must be tagged.
