Chapter 10 VLAN 10.5.5 Configure VLAN Port Settings Use the VLAN Port Setting screen to configure the static VLAN (IEEE 802.1Q) settings on a port. See Section 10.1 on page 129 for more information on static VLAN. Click the VLAN Port Setting link in the VLAN Status screen. Figure 76 Advanced Application > VLAN > VLAN Port Setting The following table describes the labels in this screen. Table 52 Advanced Application > VLAN > VLAN Port Setting LABEL GVRP Port Isolation Port * DESCRIPTION GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for switches to register necessary VLAN members on ports across the network. Select this check box to permit VLAN groups beyond the local Switch. Port Isolation allows each port to communicate only with the CPU management port and the dual personality GbE interfaces but not communicate with each other. This option is the most limiting but also the most secure. This field displays the port number. Settings in this row apply to all ports. Use this row only if you want to make some settings the same for all ports. Use this row first to set the common settings and then make adjustments on a port-by-port basis. Ingress Check PVID Note: Changes in this row are copied to all the ports as soon as you make them. If this check box is selected for a port, the Switch discards incoming frames for VLANs that do not include this port in its member set. Clear this check box to disable ingress filtering. A Port VLAN ID (PVID) is a tag that the Switch adds to incoming untagged frames received on a port so that the frames are forwarded to the VLAN group that the tag defines. Enter a number between 1 and 4094 as the port VLAN ID. VES1724-56 User's Guide 137
