DGS-3224TGR Gigabit Ethernet Switch User’s Guide Switch Management and Operating Concepts This chapter discusses many of the concepts and features used to manage the switch, as well as the concepts necessary for the user to understand the functioning of the switch. Further, this chapter explains many important points regarding these features.
Page 24: Ip Addresses And Snmp Community Names
DGS-3224TGR Gigabit Ethernet Switch User’s Guide IP Addresses and SNMP Community Names 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 25: Mibs
DGS-3224TGR Gigabit Ethernet Switch User’s Guide • New Root – This trap indicates that the switch has become the new root of the Spanning Tree, the trap is sent by the switch soon after its election as the new root. This implies that upon expiration of the Topology Change Timer the new root trap is sent out immediately after the switch’s election as the new root.
Page 26: Authentication
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Authentication The authentication protocol ensures that both the router SNMP agent and the remote user SNMP application program discard packets from unauthorized users. Authentication is accomplished using ‘community strings’, which function like passwords. The remote user SNMP application and the router SNMP must use the same community string. Packet Forwarding The switch enters the relationship between destination MAC or IP addresses and the Ethernet port or gateway router the destination resides on into its forwarding table.
Page 27: Spanning Tree
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Spanning Tree 802.1w Rapid Spanning Tree The DGS-3224TGR implements two versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol (RSTP) as defined by the IEE 802.1w specification and a version compatible with the IEEE 802.1d STP. RSTP can operate with legacy equipment implementing IEEE 802.1d, however the advantages of using RSTP will be lost.
Page 28: Vlans
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 802.1d/802.1w Compatibility RSTP can interoperate with legacy equipment and is capable of automatically adjusting BPDU packets to 802.1d format when necessary. However, any segment using 802.1 STP will not benefit from the rapid transition and rapid topology change detection of RSTP.
Page 29: Q Vlan Packet Forwarding
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 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.
Page 30: Q Vlan Tags
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 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 31: Port Vlan Id
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 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 –...
Page 32: Port-Based And Mac-Based Access Control
DGS-3224TGR Gigabit Ethernet Switch User’s Guide If the packet is not tagged with VLAN information, the ingress port will tag the packet with its own PVID as a VID. The switch then determines if the destination port is a member of the same VLAN (has the same VID) as the ingress port. If it does not, the packet is dropped.
Page 33: Authentication Server
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Authentication Server The Authentication Server is a remote device that is connected to the same network as the Client and Authenticator, must be running a RADIUS Server program and must be configured properly on the Authenticator (Switch). Clients connected to a port on the Switch must be authenticated by the Authentication Server (RADIUS) before attaining any services offered by the Switch on the LAN.
Page 34: Client
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Figure 5- 7. The Authenticator Client The Client is simply the endstation that wishes to gain access to the LAN or switch services. All endstations must be running software that is compliant with the 802.1x protocol. For users running Windows XP, that software is included within the operating system.
Page 35: Authentication Process
Figure 5- 9. The 802.1x Authentication Process The D-Link implementation of 802.1x allows network administrators to choose between two types of Access Control used on the Switch, which are: 1.

Example of Typical Port-Based Configuration Once the connected Client has successfully been authenticated, the Port then becomes Authorized, and all subsequent traffic on the Port is not subject to access control restriction until an event occurs that causes the Port to become Unauthorized.

Page 38 DGS-3224TGR Gigabit Ethernet Switch User’s Guide When the DHCP client is in the renewing state, it must release its address immediately in the rare event that the DHCP server sends a negative acknowledgment. The DHCP server sends this message to inform a client that it has incorrect configuration information, forcing it to release its current address and acquire new information.
