INTRODUCTION This chapter will describe the features of the DES-1252 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.

by clicking Apply. To refresh the information table to view the latest Link Status and Priority, press the Refresh button. Figure 25 – System > Port Setting Speed: Gigabit Fiber connections can operate in Forced Mode settings (1000M Full), Auto, or Disable. Copper connections can operate in Forced Mode settings (100M Full, 100M Half, 10M Full, 10M Half), Auto, or Disable. The default setting for all ports is Auto. 100Base-FX Fiber supports 100M full/half force mode.
NOTE: When the Combo Gigabit Fiber port and the Copper ports are both connected, the Fiber port will take precedence over the Copper ports, meaning the Fiber port will be the only connection. But, for 100M Fiber module, the Fiber port will not take precedence over the Copper ports. System > SNMP Setting Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices.
Figure 26 – System > SNMP Setting Enabled / Disabled: Default setting is Disabled. Click Enable, then Apply, to set Community Settings. The default community strings for the Switch used for SNMP v.1 management access are: Public: The community with read-only privilege allows authorized management stations to retrieve MIB objects. Private: The community with read/write privilege allows authorized management stations to retrieve and modify MIB objects.
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.
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 52 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 290 – Configuration > 802.
Figure 301 – Configuration > 802.1Q VLAN > VID Assignments 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 312 – Configuration > Trunking NOTE: Each combined trunk port must be connected to devices within the same VLAN group.
Configuration > IGMP Snooping With Internet Group Management Protocol (IGMP) snooping, the Web-Smart Switch can make intelligent multicast forwarding 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.
Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent. By adjusting the Query Interval, the number of IGMP messages can increase or decrease; larger values cause IGMP Queries to be sent less often. Default is 125 seconds. Max Response Time (10-25 sec): The Max Response Time specifies the maximum allowed time before sending a responding report.
Router Timeout (60-600 sec): This is the interval after which a learnt router port entry will be purged. For each router port learnt, a 'RouterPortPurgeTimer' runs for 'RouterPortPurgeInterval'. This timer will be restarted whenever a router control message is received over that port. If no router control messages are received for 'RouterPortPurgeInterval' time, the learnt router port entry will be purged. Default is 125 seconds.

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 356 – 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.
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 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.
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. If Enabled (default is Disabled), threshold settings of 8,000 ~ 4,096,000 bytes per second can be assigned. Press Apply for the settings to take effect.
especially in Wi-Fi wireless networks. 802.1X holds a network port disconnected until authentication is completed. The switch uses Extensible Authentication Protocol over LANs (EAPOL) to exchange authentication protocol client identity (such as a user name) with the client, and forward it to another remote RADIUS authentication server to verify access rights. The EAP packet from the RADIUS server also contains the authentication method to be used.
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. TxPeriod: Sets the number of seconds that the switch waits for a response to an EAP-request/identity frame from the client before retransmitting the request. Default is 24 seconds. ReAuthEnabled: This Enables or Disables the periodic ReAuthentication control. When the 802.
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.
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.
