INTRODUCTION This chapter will describe the features of the DES-1228 and provide some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, and management objects, but with a tenfold increase in theoretical throughput of over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet.
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.
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. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which won’t compete with each other for network transmission capacity.

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). Setting up a Trap: Select Enable, enter a Trap Name (i.e. Trap Name must be selected from a Community Name), add the IP of the device to be monitored, and choose the event(s) to trap.
(multimedia applications such as video conferencing), and therefore help to simplify network management by allowing users to move devices to a new VLAN without having to change any physical connections. The IEEE 802.1Q VLAN Configuration page provides powerful VID management functions. The original settings have the VID as 01, named “default”, and all 28 ports as “Untagged” (see Figure 29). Rename: Click to rename the VLAN group. Delete VID: Click to delete the VLAN group.
Figure 29 – Configuration > 802.1Q VLAN > Add VID Figure 280 – Configuration > 802.1Q VLAN > Example VIDs Figure 291 – Configuration > 802.
Configuration > Trunking The Trunking function enables the cascading of two or more ports for a combined larger bandwidth. Up to six Trunk groups may be created, each supporting up to 8 ports. Add a Trunking Name and select the ports to be trunked together, and click Apply to activate the selected Trunking groups. Figure 302 – Configuration > Trunking NOTE: Each combined trunk port must be connected to devices within the same VLAN group.
decisions by examining the contents of each frame’s Layer 2 MAC header. IGMP snooping can help reduce cluttered traffic on the LAN. With IGMP snooping enabled globally, the Web-Smart Switch will forward multicast traffic only to connections that have group members attached. Please note that IGMP will not alter or route IP multicast packets. To send IP multicast packets across subnetworks a multicast routing protocol will be necessary.
Max Response Time (10-25 sec): The Max Response Time specifies the maximum allowed time before sending a responding report. Adjusting this setting effects the "leave latency", or the time between the moment the last host leaves a group and when the routing protocol 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.
'RouterPortPurgeInterval' time, the learnt router port entry will be purged. Default is 125 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.

Configuration > 802.1D Spanning Tree 802.1D Spanning Tree Protocol (STP) implementation is a backup link(s) between switches, bridges or routers 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 346 – Configuration > Spanning Tree By default, Spanning Tree is Disabled.
After Enabling STP, setting the STP Global Setting includes the following options: 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.
greater the probability the port will be chosen to forward packets. The default value is 19. 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.
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 gets sent to the source and forwards it to the Target Port. Both (transmit and receive) mode: Duplicate both the data transmitted from and data sent to the source port, and forwards all the data to the assigned Target Port. None: Turns off the mirroring of the port. QoS > 802.
Security > Safeguard Engine D-Link’s Safeguard Engine is a robust and innovative technology that automatically throttles the impact of packet flooding into the switch's CPU. This function helps protect the Web-Smart Switch from being interrupted by malicious viruses or worm attacks. By default this is Enabled. Figure 39 – Security > Safeguard Engine Security > Broadcast Storm Control The Broadcast Storm Control feature provides the ability to control the receive rate of broadcasted packets.
configuration also allows unauthorized personnel to easily intrude and possibly gain access to sensitive data. IEEE-802.1X provides a security standard for network access control, especially in Wi-Fi wireless networks. 802.1X holds a network port disconnected until authentication is completed.
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.
To establish 802.1X port-specific assignments, select the From and To Ports and select Enable. 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). The Macs listed on this table may only connect from corresponding ports and VIDs, in order to protect the network from illegal Macs.
The Static Mac Address Setting table displays the static Mac addresses connected, as well as the VID. Press Delete to remove a device. To add a new Mac address assignment, press Add Mac, then select the assigned Port number, enter both the Mac Address and VID and press Apply. Security > Mac Address Table > Dynamic Forwarding Table For each port, this table displays the Mac address of each packet passing through the Switch.
Monitoring > Statistics The Statistics screen displays the status of each port packet count. Figure 414 – 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.
