VLAN ID 3, Port 4 to TAGGED using the Static VLAN Egress Configuration screen. This
means that these ports will only transmit tagged VLAN frames.
• Port 4, Egress: TAGGED

By default the port remains as a member of the Default VLAN. With the original classification
information inserted in the frame Tag Header, the receiving switch will maintain the original
frame classification. GVRP is enabled on this port and will support dynamic VLANs created by
GVRP.
