This method is called Priority Tagging (p tagwithout Q tag). If the parameter VlanSendNonTaggedOnNative is set to 1, the gatewaysends regular packets (with no VLAN tag). Incoming packets (from the switch to the gateway):The switch sends all packets intended for the gateway (according to the switch’sconfiguration) to the gateway without altering them. For packets whose VLAN ID isidentical to the switch’s PVID. In this case, the switch removes the tag and sends apacket.The gateway only accepts packets that have a VLAN ID identical to one of its interfaces(control, media or OAM). Packets with a VLAN ID that is 0 or packets without a tag areaccepted only if the gateway’s native VLAN ID is identical to the VLAN ID of one of itsinterfaces. In this case, the packets are sent to the relevant interface. All other packetsare rejected.Getting Started with VLANS and Multiple IPsBy default the gateway operates without VLANs and multiple IPs, using a single IP address,subnet mask and default gateway IP address. This section provides an example of theconfiguration required to integrate the gateway into a VLAN and multiple IPs network usingthe Embedded Web Server (see Integrating Using the Embedded Web Server) and ini file(see Integrating Using the ini File).Table 54 shows an example configuration that is implemented in the following sections.
