ProSAFE 8-Port or 16-Port Gigabit Smart Managed Switch Model GS418TPP, GS510TLP, and GS510TPP 12. From the Ingress Filtering menu, select one of the following options: • Enable. The frame is discarded if this port is not a member of the VLAN with which this frame is associated. In a tagged frame, the VLAN is identified by the VLAN ID in the tag. In an untagged frame, the VLAN is the port VLAN ID specified for the port that received this frame. • Disable. All frames are forwarded in accordance with the 802.1Q VLAN bridge specification. The default is Disable. 13. In the Port Priority field, specify the default 802.1p priority assigned to untagged packets arriving at the port. You can enter a number from 0 to 7. 14. Click the Apply button. The updated configuration is sent to the switch. Configuration changes take effect immediately. The following table describes the nonconfigurable fields. Table 34. Nonconfigurable fields on the PVID Configuration page Field Current Ingress Filtering Untagged VLANs Tagged VLANs Forbidden VLANs Dynamic VLANs Description Indicates whether ingress filtering is enabled for the interface. The number of untagged VLANs for the interface. The number of tagged VLANs for the interface. The number of forbidden VLANs for the interface. The number of dynamically added VLANs for the interface. Configure a MAC-Based VLAN The MAC-Based VLAN feature allows incoming untagged packets to be assigned to a VLAN and thus classify traffic based on the source MAC address of the packet. You define a MAC-to-VLAN mapping by configuring an entry in the MAC-to-VLAN table. An entry is specified through a source MAC address and the desired VLAN ID. The MAC-to-VLAN configurations are shared across all ports of the device (that is, a system-wide table exists with MAC address-to-VLAN ID mappings). When untagged or priority-tagged packets arrive at the switch and entries exist in the MAC-to-VLAN table, the source MAC address of the packet is looked up. If an entry is found, the corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it maintains this value. Otherwise, the priority is set to zero. The assigned VLAN ID is verified against the VLAN table. If the VLAN is valid, ingress processing on the packet continues. Otherwise, the packet is dropped. This implies that the user is allowed to configure a MAC address mapping to a VLAN that was not created on the system. Configure Switching 142
