DGS-3024 Gigabit Ethernet Switch Manual associated with the delivery of time critical data over congested networks. The quality of applications that are dependent on such time critical data, such as video conferencing, can be severely and adversely affected by even very small delays in transmission. Network devices that are in compliance with the IEEE 802.1p standard have the ability to recognize the priority level of data packets. These devices can also assign a priority label or tag to packets.
DGS-3024 Gigabit Ethernet Switch Manual Ingress port – A port on a Switch where packets are flowing into the Switch and VLAN decisions must be made. Egress port – A port on a Switch where packets are flowing out of the Switch, either to another Switch or to an end station, and tagging decisions must be made. IEEE 802.1Q (tagged) VLANs are implemented on the Switch. 802.1Q VLANs require tagging, which enables them to span the entire network (assuming all Switches on the network are IEEE 802.
DGS-3024 Gigabit Ethernet Switch Manual Figure 7- 29. IEEE 802.1Q Packet Forwarding 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet's EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
DGS-3024 Gigabit Ethernet Switch Manual Figure 7- 30. IEEE 802.1Q Tag The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated. Figure 7- 31. Adding an IEEE 802.1Q Tag Port VLAN ID Packets that are tagged (are carrying the 802.1Q VID information) can be transmitted from one 802.
DGS-3024 Gigabit Ethernet Switch Manual table). If the PVID of the port that received the packet is different from the PVID of the port that is to transmit the packet, the Switch will drop the packet. Within the Switch, different PVIDs mean different VLANs (remember that two VLANs cannot communicate without an external router). Therefore, VLAN identification based upon the PVIDs cannot create VLANs that extend outside a given Switch (or Switch stack). Every physical port on a Switch has a PVID. 802.
DGS-3024 Gigabit Ethernet Switch Manual Default VLANs The Switch initially configures one VLAN, VID = 1, called "default." The factory default setting assigns all ports on the Switch to the "default." Packets cannot cross VLANs. If a member of one VLAN wants to connect to another VLAN, the link must be through an external router. NOTE: If no VLANs are configured on the Switch, then all packets will be forwarded to any destination port. Packets with unknown source addresses will be flooded to all ports.
