[. . . ] Select this check box to activate ingress filtering on the switch. Clear this check box to disable ingress filtering the switch. Enter a number between 1and 4094 as the port VLAN ID. Select this check box to allow GVRP on this port. Port Isolation Ingress Check Port PVID GVRP Acceptable Frame Specify the type of frames allowed on a port. Type Select All from the drop-down list box to accept all untagged or tagged frames on this port. Select Tag Only to accept only tagged frames on this port. VLAN Trunking Enable VLAN Trunking on ports connected to other switches or routers (but not ports directly connected to end users) to allow frames belonging to unknown VLAN groups to pass through the switch.

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. Note: When you activate port-based VLAN, the switch uses a default VLAN ID of 1. In screens (such as IP Setup and Filtering) that require a VID, you must enter 1 as the VID. The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN with all Ethernet ports. 8. 6. 1 Configure a Port-based VLAN Select Port Based as the VLAN Type in the Switch Setup screen (see Figure 32 on page 70) and then click VLAN from the navigation panel to display the next screen. 74 Chapter 8 VLAN ES-2108/ES-2108-G User's Guide Figure 36 Port Based VLAN Setup (All Connected) Figure 37 Port Based VLAN Setup (Port Isolation) The following table describes the labels in this screen. Chapter 8 VLAN 75 ES-2108/ES-2108-G User's Guide Table 17 Port Based VLAN Setup LABEL Setting Wizard DESCRIPTION Choose All connected or Port isolation. All connected means all ports can communicate with each other, that is, there are no virtual LANs. All incoming and outgoing ports are selected. This option is the most flexible but also the least secure. Port isolation means that each port can only communicate with the CPU management port and cannot communicate with each other. All incoming ports are selected while only the CPU outgoing port is selected. This option is the most limiting but also the most secure. After you make your selection, click Apply (top right of screen) to display the screens as mentioned above. You can still customize these settings by adding/deleting incoming or outgoing ports, but you must also click Apply at the bottom of the screen. [. . . ] The number of "borrowed" host ID bits determines the number of subnets you can have. The remaining number of host ID bits (after "borrowing") determines the number of hosts you can have on each subnet.
