Purpose This guide discusses how to install and use the configuration functions of the DGS-1224T Web-Smart Switch.
INTRODUCTION This chapter describes the features of the DGS-1224T 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.

Add a Trunking Name and select the ports to be trunked together, and click Apply to activate the selected Trunking groups. Figure 33 – Configuration > Trunking NOTE: Each combined trunk port must be connected to devices within the same VLAN group.
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.
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.
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.
To view the Multicast Entry Table for a given VLAN, press the View button.
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.
Bridge Priority: This value between 0 and 65535 specifies the priority for forwarding packets: the lower the value, the higher the priority. The default is 32768. Bridge Max Age: This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information.
Path Priority: Select a value between 0 and 255 to specify the priority for a specified port for forwarding packets: the lower the value, the higher the priority. The default is 128. Configuration > Port Mirroring Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of the Switch to another port where the packet can be studied. This enables network managers to better monitor network performances.
RX (receive) mode: Duplicates the data that send to the source and forwards it to the Target Port. Both (transmit and receive) mode: Duplicate both the data transmitted from and data send to the source port, and forwards all the data to the assigned Target Port. None: Turns off the mirroring of the 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.
flooding into the switch's CPU. This function helps protect the WebSmart Switch from being interrupted by malicious viruses or worm attacks. 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 bytes per second can be assigned. Press Apply for the settings to take effect.
Figure 41 – Security > Broadcast Storm Control Security > 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 – QoS > 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). Figure 43 – Security > Static Mac Address To initiate the removal of auto-learning for any of the uplink ports, press On to enable this feature, and select the port(s) for auto learning to be disabled.
Security > Mac Address Table > Dynamic Forwarding Table For each port, this table displays the Mac address of each packet passing through the Switch. To add a Mac address to the Static Mac Address List, click the Add checkbox associated with the identified packet.
Monitoring > Statistics The Statistics screen displays the status of each port packet count. Figure 45 – Monitoring > Statistics Refresh: To renew the details collected and displayed. Clear Counter: To reset the details displayed. TxOK: Number of packets transmitted successfully. RxOK: Number of packets received successfully.
