PAGE 60
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch Parameter Description Unit This is the Unit ID of a switch in a switch stack. VID The VLAN ID of the VLAN the corresponding MAC address belongs to. Multicast MAC Address The MAC address of the static source of multicast packets. This must be a multicast MAC address.
PAGE 61
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch Remember, the priority queue settings on the Switch are for all ports, and all devices connected to the Switch will be affected. This priority queuing system will be especially beneficial if your network employs switches with the capability of assigning priority tags. VLANs A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout.
PAGE 62
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLANs allows VLANs to work with legacy switches that don’t recognize VLAN tags in packet headers. The tagging feature allows VLANs to span multiple 802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled on all ports and work normally. The IEEE 802.
PAGE 63
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag. The tag is contained in the following two octets and consists of 3 bits of user priority, 1 bit of Canonical Format Identifier (CFI – used for encapsulating Token Ring packets so they can be carried across Ethernet backbones), and 12 bits of VLAN ID (VID). The 3 bits of user priority are used by 802.1p. The VID is the VLAN identifier and is used by the 802.1Q standard.
PAGE 64
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch Port VLAN ID Packets that are tagged (are carrying the 802.1Q VID information) can be transmitted from one 802.1Q compliant network device to another with the VLAN information intact. This allows 802.1Q VLANs to span network devices (and indeed, the entire network, if all network devices are 802.1Q compliant). Unfortunately, not all network devices are 802.1Q compliant. These devices are referred to as tag-unaware. 802.
PAGE 65
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch 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. If ingress filtering is enabled for a port, the switch will examine the VLAN information in the packet header (if present) and decide whether or not to forward the packet.
PAGE 66
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch On port-based VLANs, NICs do not need to be able to identify 802.1Q tags in packet headers. NICs send and receive normal Ethernet packets. If the packet’s destination lies on the same segment, communications take place using normal Ethernet protocols. Even though this is always the case, when the destination for a packet lies on another switch port, VLAN considerations come into play to decide if the packet gets dropped by the switch or delivered.

D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch Figure 4- 24. GVRP Settings and GVRP Table The following fields can be set: Parameter Description Unit Displays the Unit ID of the switch − within the switch stack − that the VLAN will be created on. From/To These two fields allow you to specify the range of ports that will be included in the Port-based VLAN that you are creating using the 802.1Q Port Settings page.
PAGE 70
D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch Ingress Check This field can be toggled using the space bar between Enabled and Disabled. Enabled enables the port to compare the VID tag of an incoming packet with the PVID number assigned to the port. If the two are different, the port filters (drops) the packet. Disabled disables Ingress filtering. Ingress Checking is disabled by default. Acceptable Frame Type This field denotes the type of frame that will be accepted by the port.

D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch RIP does not have an explicit method to detect routing loops. Many RIP implementations include an authorization mechanism (a password) to prevent a router from learning erroneous routes from unauthorized routers. To maximize stability, the hop count RIP uses to measure distance must have a low maximum value. Infinity (that is, the network is unreachable) is defined as 16 hops.
