This device integrates 1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Purpose This guide discusses how to install and use the configuration functions of the DGS-1216T Web-Smart Switch.
INTRODUCTION This chapter describes the features of the DGS-1216T and provides some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow’s rapidly improving switching and routing internetworking technologies.
Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network.
so broadcast and multicast traffic use valuable network bandwidth more efficiently. Additional VLAN benefits include: Security: Security is increased with the reduction of opportunity in eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN. Cost Reduction: VLANs can be used to create multiple broadcast domains, thus eliminating the need of expensive routers. VID: VLAN ID is an identification of up to 4094 possible VLANs.

defines both the format of the MIB specifications and the protocol used to access this information over the network. Community Setting: In support of SNMP version 1, the Web-Smart Switch accomplishes user authentication by using Community Settings that function as passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from a station that are not authenticated are ignored (dropped).
Private: The community with read/write privilege allows authorized management stations to retrieve and modify MIB objects. Trap Setting: Traps are messages that alert network personnel of events that occur on the Switch. Such events can be as serious as a reboot (someone accidentally turned the Switch OFF), or less serious events such as a port status change. The Switch can generate traps and send them to the trap recipient (i.e. network administrator).

header. IGMP snooping can help reduce cluttered traffic on the LAN. With IGMP snooping enabled globally, the Web-Smart Switch will forward IP multicast traffic only to connections that have group members attached. Figure 34 – Configuration > IGMP Snooping Configuration By default, IGMP is Disabled. If Enabled, the IGMP Global Settings will need to be entered: Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent.
is notified that there are no more members. It also allows adjustments for controlling the frequency of IGMP traffic on a subnet. Default is 10 seconds. Robustness Variable (1-255 sec): The Robustness Variable allows adjustment for the expected packet loss on a subnet. If a subnet is expected to be lossy, the Robustness Variable may be increased. The Robustness Variable can not be set zero, and SHOULD NOT be one. Default is 2 seconds.
Leave Timer (0-25 sec): This is the interval after which a Leave message is forwarded on a port. When a leave message from a host for a group is received, a group-specific query is sent to the port on which the leave message is received. A timer is started with a time interval equal to IgsLeaveProcessInterval. If a report message is received before above timer expires, the Leave message is dropped. Otherwise the Leave message is either forwarded to the port. Default is 1 second.
Figure 36 – Configuration > IGMP Multicast Entry Table Configuration > 802.1D Spanning Tree 802.1D Spanning Tree Protocol (STP) implementation is designed to prevent network loops that could cause a broadcast storm. When physical links forming a loop provide redundancy, only a single path will be forwarding frames. If the link fails, STP activates a redundant link automatically.
Figure 37 – Configuration > Spanning Tree By default, Spanning Tree is Disabled. If Enabled, the Switch will listen for BPDU packets and its accompanying Hello packet. BPDU packets are sent even if a BPDU packet was not received. Therefore, each link between bridges is sensitive to the status of the link. Ultimately this difference results in faster detection of failed links, and thus faster topology adjustment. A draw-back of 802.1D is this absence of immediate feedback from adjacent bridges.
information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the value ages out and a BPDU has still not been received from the Root Bridge, the Switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it turns out that the Switch has the lowest Bridge Identifier, it will become the Root Bridge.
Switch to another port where the packet can be studied. This enables network managers to better monitor network performances. Figure 38 – Configuration > Port Mirroring Selection options for the Source Ports are as follows: TX (transmit) mode: Duplicates the data transmitted from the source port and forwards it to the Target Port. RX (receive) mode: Duplicates the data that send to the source and forwards it to the Target Port.
QoS > 802.1p Default Priority This feature displays the status Quality of Service priority levels of each port, and for ports that are Untagged, the priority can be adjusted. Figure 39 – QoS > 802.1p Default Priority Security > Safeguard Engine By default is Enabled, D-Link’s Safeguard Engine is a robust and innovative technology that automatically throttles the impact of packet flooding into the switch's CPU.
Figure 40 – Security > Safeguard Engine Security > Broadcast Storm Control The Broadcast Storm Control (BSC) feature provides the ability to control the receive rate of broadcasted packets. If Enabled (default is Disabled), threshold settings of 8,000; 16,000; 32,000; 64,000; 128,000; 256,000; 512,000; 1,024,000; 2,048,000; 4,096,000 bytes per second can be assigned. Press Apply for the settings to take effect.
Figure 41 – Security > Broadcast Storm Control Security > 802.1X > 802.1X Setting IEEE-802.1X provides a security standard for network access control, predominantly in Wi-Fi wireless networks. 802.1X holds a network port disconnected until authentication is completed. Depending on the results, the port is either made available to the user, or the user is denied access to the network. 802.1X uses the Extensible Authentication Protocol (EAP) for passing authentication messages.
Figure 42 –Security > 802.1X > 802.1X Setting By default, 802.1X is Disabled. To use EAP for security, select Enabled and set the 802.1X Global Settings for the Radius Server and applicable authentication information. Authentication Port: sets primary port for security monitoring. Default is 1812. Key: Masked password matching the Radius Server Key. Confirm Key: Enter the Key a second time for confirmation.
QuietPeriod: Sets the number of seconds that the switch remains in the quiet state following a failed authentication exchange with the client. Default 80 seconds SuppTimeout: Sets the switch-to-client retransmission time for the EAP-request frame. Default is 12 seconds. ServerTimeout: Sets the amount of time the switch waits for a response from the client before resending the response to the authentication server. Default is 16 seconds.
Security > Mac Address Table > Static MAC This page provides two distinct features. The top table provides the ability to turn off auto learning Mac address if a port isn't connected to an uplink Switch (i.e. DHCP Server). By default, this feature is OFF (disabled).
