Dual-mode VLAN ports
Configuring a tagged port as a dual-mode port allows it to accept and transmit both tagged traffic
and untagged traffic at the same time. A dual-mode port accepts and transmits frames belonging
to VLANs configured for the port, as well as frames belonging to the default VLAN (that is, untagged
traffic).
For example, in Figure 93, port 2/11 is a dual-mode port belonging to VLAN 20. Traffic for VLAN 20,
as well as traffic for the default VLAN, flows from a hub to this port. The dual-mode feature allows
traffic for VLAN 20 and untagged traffic to go through the port at the same time.
