Page 29: Snmp Settings
DGS-3024 Gigabit Ethernet Switch Manual SNMP Settings Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, Switches, and other network devices.
Page 30: Ip Address Assignment
DGS-3024 Gigabit Ethernet Switch Manual IP Address Assignment Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch's default IP address is 10.90.90.90. You can change the default Switch IP address to meet the specification of your networking address scheme.
Page 31: Connecting Devices To The Switch
DGS-3024 Gigabit Ethernet Switch Manual Figure 5- 4. Assigning the Switch an IP Address In the above example, the Switch was assigned an IP address of 10.53.13.224 with a subnet mask of 255.0.0.0.

Speed/Duplex Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the port. Auto denotes auto-negotiation between 10 and 100 Mbps devices, in full- or half-duplex.
Page 42: Port Description
DGS-3024 Gigabit Ethernet Switch Manual Port Description The DGS-3024 supports a port description feature where the user may name various ports on the Switch. To assign names to various ports, click the Port Description in the Port Configuration folder of the Configuration menu. Use the From and To pull-down menu to choose a port or range of ports to describe, and then enter a description of the port(s).
Page 43: Port Mirroring
DGS-3024 Gigabit Ethernet Switch Manual Port Mirroring The Switch allows the user to copy frames transmitted and received on a port and redirect the copies to another port. The user can attach a monitoring device to the mirrored port, such as a sniffer or an RMON probe, to view details about the packets passing through the first port.
Page 44: Link Aggregation (Port Trunking)
DGS-3024 Gigabit Ethernet Switch Manual Link Aggregation (Port Trunking) Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. NOTE: Static Type Link Aggregation is usually referred as “Port Trunking.” In this section, the terms “Link Aggregation” and “Port Trunking” will be used synonymously.
Page 45 DGS-3024 Gigabit Ethernet Switch Manual NOTE: If any ports within the trunk group become disconnected, packets intended for the disconnected port will be load shared among the other uplinked ports of the port trunking group. Port trunking 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.
Page 46 DGS-3024 Gigabit Ethernet Switch Manual Figure 7- 9. Port Trunking Configuration window The user-changeable parameters are as follows: Parameter Description Select an ID number for the group, between 1 and 4. Group ID [1-4] Trunk groups can be toggled between Enabled and Disabled. This is used to turn a port trunking State group on or off.
Page 47: Lacp Port Settings
DGS-3024 Gigabit Ethernet Switch Manual LACP Port Settings The LACP Port Settings window is used in conjunction with the Link Aggregation window to create port trunking groups on the Switch. Using the following window, the user may set which ports will be active and passive in processing and sending LACP control frames.
Page 48: Igmp Snooping
DGS-3024 Gigabit Ethernet Switch Manual IGMP Snooping Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent between network stations or devices and an IGMP host. When enabled for IGMP snooping, the Switch can open or close a port to a specific device based on IGMP messages passing through the Switch.
Page 49 DGS-3024 Gigabit Ethernet Switch Manual Parameter Description This is the VLAN ID that, along with the VLAN Name, identifies the VLAN for which to modify VLAN ID the IGMP Snooping Settings. This is the VLAN Name that, along with the VLAN ID, identifies the VLAN for which to modify VLAN Name the IGMP Snooping Settings.
Page 50: Static Router Ports Entry
DGS-3024 Gigabit Ethernet Switch Manual Static Router Ports Entry A static router port is a port that has a multicast router attached to it. Generally, this router would have a connection to a WAN or to the Internet. Establishing a router port will allow multicast packets coming from the router to be propagated through the network, as well as allowing multicast messages (IGMP) coming from the network to be propagated to the router.
Page 51: Spanning Tree
STP will be familiar to most networking professionals. However, since 802.1w RSTP and 802.1s MSTP has been recently introduced to D-Link managed Ethernet Switches, a brief introduction to the technology is provided below followed by a description of how to set up 802.1d STP, 802.1w RSTP and 802.1s MSTP.
Page 52: Port Transition States
DGS-3024 Gigabit Ethernet Switch Manual Port Transition States An essential difference between the three protocols is in the way ports transition to a forwarding state and in the way this transition relates to the role of the port (forwarding or not forwarding) in the topology. MSTP and RSTP combine the transition states disabled, blocking and listening used in 802.1d and creates a single state Discarding.
Page 53: Stp Loopback Detection
DGS-3024 Gigabit Ethernet Switch Manual STP Loopback Detection When connected to other switches, STP is an important configuration in consistency for delivering packets to ports and can greatly improve the throughput of your switch. Yet, even this function can malfunction with the emergence of STP BPDU packets that occasionally loop back to the Switch, such as BPDU packets looped back from an unmanaged switch connected to the DGS- 3024.

DGS-3024 Gigabit Ethernet Switch Manual VLANs Understanding IEEE 802.1p Priority Priority tagging is a function defined by the IEEE 802.1p standard designed to provide a means of managing traffic on a network where many different types of data may be transmitted simultaneously. It is intended to alleviate problems associated with the delivery of time critical data over congested networks.

DGS-3024 Gigabit Ethernet Switch Manual IEEE 802.1Q VLANs Some relevant terms: Tagging – The act of putting 802.1Q VLAN information into the header of a packet. Untagging – The act of stripping 802.1Q VLAN information out of the packet header. Ingress port –...
Page 69: 802.1Q Vlan Tags
DGS-3024 Gigabit Ethernet Switch Manual 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.
Page 70: Port Vlan Id
DGS-3024 Gigabit Ethernet Switch Manual 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).
Page 71: Default Vlans
DGS-3024 Gigabit Ethernet Switch Manual ingress port. If it does not, the packet is dropped. If it has the same VID, the packet is forwarded and the destination port transmits it on its attached network segment. This process is referred to as ingress filtering and is used to conserve bandwidth within the Switch by dropping packets that are not on the same VLAN as the ingress port at the point of reception.

Page 78: Qos
DGS-3024 Gigabit Ethernet Switch Manual The DGS-3024 supports 802.1p priority queuing Quality of Service. The following section discusses the implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing. Advantages of QoS QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), Web browsing applications, file server applications or video conferencing.
Page 79: Understanding Qos
DGS-3024 Gigabit Ethernet Switch Manual Understanding QoS The Switch has four priority queues. These priority queues are labeled as 3, the highest queue to 0, the lowest queue. The eight priority tags, specified in IEEE 802.1p are mapped to the Switch's priority tags as follows: Priority 0 is assigned to the Switch's Q1 queue.
