xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch equated to a broadcast domain, because broadcast packets are forwarded to only members of the VLAN on which the broadcast was initiated. Notes about VLANs on the DGS-3400 Series No matter what basis is used to uniquely identify end nodes and assign these nodes VLAN membership, packets cannot cross VLANs without a network device performing a routing function between the VLANs. The xStack DGS-3400 Series supports IEEE 802.
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Figure 7- 1. 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.
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch 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- 3. 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.
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch will have no 802.1Q VLAN information. (Remember that the PVID is only used internally within the Switch). Untagging is used to send packets from an 802.1Q-compliant network device to a non-compliant network device. Ingress Filtering A port on a switch where packets are flowing into the Switch and VLAN decisions must be made is referred to as an ingress port.
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch VLAN Segmentation Take for example a packet that is transmitted by a machine on Port 1 that is a member of VLAN 2. If the destination lies on another port (found through a normal forwarding table lookup), the Switch then looks to see if the other port (Port 10) is a member of VLAN 2 (and can therefore receive VLAN 2 packets). If Port 10 is not a member of VLAN 2, then the packet will be dropped by the Switch and will not reach its destination.

xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Trunking Understanding Port Trunk Groups Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. DGS-3400 Series supports up to 32 port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can be achieved. Figure 7- 16. Example of Port Trunk Group The Switch treats all ports in a trunk group as a single port.
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch NOTE: If any ports within the trunk group become disconnected, packets intended for the disconnected port will be load shared among the other linked ports of the link aggregation group. NOTE: Trunking may be done across switches in the switch stack without any limitations. Link aggregation allows several ports to be grouped together and to act as a single link. This gives a bandwidth that is a multiple of a single link's bandwidth.
