Chapter 14 Switch Configuration The following table describes the labels in this screen for each VLAN port type. Table 97 VLAN Port Type Descriptions LABEL DESCRIPTION Egress Ports A port that is in the egress list in a VLAN. Only select this if the connected device supports IEEE 802.1Q VLAN. Forbidden Ports A port that is blocked from joining a VLAN group. No frames are transmitted through this port. Untag Ports A port that does not tag all outgoing frames transmitted. Normal Tagged Port A port that joins a VLAN group using GVRP. Outgoing frames are tagged on this port. 14.10.3 Introduction to Port-based VLANs Port-based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address and its associated port. Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if you wish to allow two subscriber ports to talk to each other, for example, between conference rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port through which a data packet leaves) for both ports. Port-based VLANs are specific only to the switch on which they were created. The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN with all Ethernet ports. 14.10.4 Configuring Port Based VLAN Follow the steps below to set the Port Based VLAN Type on the switch. 1 In the Device Panel list, select a device and then right-click. 2 Click Configuration > Switch Configuration > VLAN.
