Chapter 9 VLAN The following table describes the labels in this screen. Table 19 Advanced Application > VLAN > VLAN Port Setting LABEL GVRP 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. Port * Select this check box to permit VLAN groups beyond the local Switch. 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 GVRP Acceptable Frame Type VLAN Trunking Isolation Apply Cancel 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 PVID (Port VLAN ID) is a tag that 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. Select this check box to allow GVRP on this port. Specify the type of frames allowed on a port. Choices are All, Tag Only and Untag Only. Select All from the drop-down list box to accept all untagged or tagged frames on this port. This is the default setting. Select Tag Only to accept only tagged frames on this port. All untagged frames will be dropped. Select Untag Only to accept only untagged frames on this port. All tagged frames will be dropped. 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. Select this to allows this port to communicate only with the CPU management port and the ports on which the isolation feature is not enabled. Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the nonvolatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. XGS4700-48F User's Guide 127
