10/100 Auto Negotiation Switch User’s Guide must use the correct pin arrangement in order for the DES-3216 to work properly. See Figure 3 for an example of straight through and crossover cable.
10/100 Auto Negotiation Switch User’s Guide Ports MDI-X Port MDI-X ports are crossover ports. The pin arrangement is the same as the arrangement in a crossover cable. The advantage of an MDI-X port is that you can connect a device with an MDI-II port without using a crossover cable. The steps for connecting the DES-3216 to 10 Mbps devices or 100 Mbps devices are the same. All the ports will auto negotiate the proper speed and duplex mode. The DES-3216 has one row of 16 MDI-X ports.
10/100 Auto Negotiation Switch User’s Guide 4 LEDs The LED panel of the DES-3216, displayed in Figure 4, is designed to allow you to manage the DES-3216 at a glance. The LEDs indicate the following: • Power • Speed • Link • Activity • Duplex mode All of the LEDs are described in detail. Use the tables to determine the meaning of each LED.
10/100 Auto Negotiation Switch User’s Guide Power LED The power LED lights when the DES-3216 is powered on. The purpose is to confirm that the DES-3216 is getting adequate power. See Figure 4.

This is a global setting that affects all the ports except the RS-232 port.
10/100 Auto Negotiation Switch User’s Guide byte packets are delayed by 1200 microseconds in a Store and Forward device versus 60 microseconds in a Cut-Through device. Store and Forward requires more memory because the DES-3216 must store the packet before sending it out. Advantages of Cut-Through Cut-Through is faster because the packet is sent as soon as the first 128 bytes are received. Cut-Through requires less memory since the DES-3216 only reads the address but does not store the entire message.

10/100 Auto Negotiation Switch User’s Guide Switch Port Configuration The Switch Port Configuration panels are used to configure individual ports on the DES3216. The only difference between the panels is the port number that they deal with. The options and settings are the same for each. Select the group of ports that you want to configure and then go to the appropriate panel. Follow these steps to select a panel: 1. Decide which group of ports you would like to work with. 2.
10/100 Auto Negotiation Switch User’s Guide Switch Port Configuration Menu The Switch Port Configuration menu, displayed in Figure 23, enables you to change the configurations of individual ports. Figure 23: Switch Port Configuration menu State All ports have two states: enabled or disabled. Enabled ports transmit and receive data packets. Disabled ports can not transmit or receive packets. You can disable a port but you will not be able to use a disabled port.
10/100 Auto Negotiation Switch User’s Guide Ports set in the 10Tx/Half state are set to work at 10 Mbps half duplex. Ports set in the 10Tx/Full state are set to work at 10 Mbps full duplex. Port State All ports have four states: blocking, listening, learning and forwarding. Blocking means that nothing is coming through the port. If the Spanning Tree Algorithm detects a loop it will change the state of the port where the loop is detected to the Blocking State. You can disable the Spanning Tree Algorithm.
10/100 Auto Negotiation Switch User’s Guide Spanning Tree Configuration The Spanning Tree Configuration panel is used to configure the Spanning Tree Algorithm. The Spanning Tree Algorithm (STA) in the DES-3216 allows you to create alternative paths (using multiple switches or bridges) in your network. These backup paths are idle until the DES-3216 determines that a problem has developed in the primary path. If the primary path breaks down STA will activate the backup path.
10/100 Auto Negotiation Switch User’s Guide Bridge Priority The Bridge Priority can be from 0 to 65535. Zero is the highest Bridge Priority. The higher the Bridge Priority the greater the chance that the DES-3216 will be selected as the Root Bridge. The DES-3216 with the highest Bridge Priority is the Root Bridge. Root Cost The Root Cost is the number of times a packet is regenerated before reaching its destination. A source sends a packet to the first device (switch or hub) on the network.
10/100 Auto Negotiation Switch User’s Guide Root Port Specifies the preferred path to the Root Bridge. Only one path per bridge can exist. The default setting is none. Table 4: User Selective STA parameters STA parameters Settings Effects Comment Enable/Disable Enable/ Disable Enable in a SNMP network.
10/100 Auto Negotiation Switch User’s Guide SNMP Management Configuration The SNMP Management Configuration panel is used to configure the DES-3216 for SNMP management. Leave the default values in place if you are not managing your network through SNMP. The DES-3216 uses the standard MIB-II Management Information Base module. The MIB values can be retrieved from any SNMP based network manager. The DES-3216 supports its own proprietary enterprise as an extended MIB.
10/100 Auto Negotiation Switch User’s Guide Figure 25: SNMP Management Configuration menu SNMP Manager Setting The fields under this setting are used to configure the DES-3216 for SNMP Management. You must configure these fields in order to manage the DES-3216 through SNMP. SNMP Community String The SNMP Community String field allows you to name the SNMP Communities. The names public and private are only default names.
10/100 Auto Negotiation Switch User’s Guide SNMP Trap Manager Setting Enables you to enter the IP addresses of Trap Managers. Traps are messages the DES-3216 sends out to inform trap managers of events on the network. The DES-3216 generates traps and sends them to the network manager. Trap managers are special network users who are given certain rights and access to oversee and maintain the network. This feature is available only in D-View or by using other SNMP management software.
10/100 Auto Negotiation Switch User’s Guide Follow these steps to configure the SNMP Trap Manager Setting: 1. Enter the IP Address of the Trap Manager. 2. Enter the name of the SNMP Community String. 3. Select Status and toggle the space bar to select Valid or Invalid. 4. Select Save and press Enter.
10/100 Auto Negotiation Switch User’s Guide VLAN Port Management A Virtual Local Area Network (VLAN) is a logical subgroup within a LAN that is created with software rather than physical connections. The purpose of a VLAN is to prevent broadcast storms and ease congestion on your network. Each VLAN created is a broadcast domain. A broadcast is a packet that is sent to all nodes on the network. A broadcast domain is a domain in which every node in the domain receives the broadcast packet.
