24-port NWay Ethernet Switch User’s Guide 1 I NTRODUCTION This section describes the features of the Switch, as well as giving some background information about Ethernet/Fast Ethernet, Gigabit Ethernet, and switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks.
24-port NWay Ethernet Switch User’s Guide Switching Technology Another key development pushing the limits of Ethernet technology is in the field 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.
24-port NWay Ethernet Switch User’s Guide ♦ RS-232 DCE Diagnostic port (console port) for setting up and managing the Switch via a connection to a console terminal or PC using a terminal emulation program. Performance features ♦ Store and forward switching scheme capability to support rate adaptation and protocol conversion. ♦ Full- and half-duplex for both 10Mbps and 100Mbps connections.

24-port NWay Ethernet Switch User’s Guide 4 C ONNECTING T HE S WITCH This chapter describes how to connect the DES-3225G to your Fast Ethernet network. Switch to End Node End nodes include PCs outfitted with a 10, 100 or 10/100 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface Card (NIC) and most routers. The RJ-45 UTP ports on NICs and most routers are MDI-II. When using a normal straight-through cable, an MDI-II port must connect to an MDI-X port.
24-port NWay Ethernet Switch User’s Guide ♦ A 10BASE-T hub or switch can be connected to the Switch via a two-pair Category 3, 4 or 5 UTP/STP straight cable. ♦ A 100BASE-TX hub or switch can be connected to the Switch via a two-pair Category 5 UTP/STP straight cable.
24-port NWay Ethernet Switch User’s Guide 5 S WITCH MANAGEMENT C ONCEPTS This chapter discusses many of the features used to manage the switch, and explains many concepts and important points regarding these features. Configuring the switch to implement these concepts is discussed in detail in the next chapters. Local Console Management Local console management involves the administration of the DES-3225G Switch via a direct connection to the RS-232 DCE console port.
-port NWay Ethernet Switch User’s Guide IP Addresses and SNMP Community Names Each Switch has its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). You can change the default Switch IP Address to meet the specification of your networking address scheme. In addition, you can also set an IP Address for a gateway router.
24-port NWay Ethernet Switch User’s Guide Topology Change Timer the new root trap is sent out immediately after the Switch’s selection as a new root. ♦ Topology Change A Topology Change trap is sent by the Switch when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a new root trap is sent for the same transition.
24-port NWay Ethernet Switch User’s Guide Aging Time The Aging Time is a parameter that affects the auto-learn process of the Switch in terms of the network configuration. Dynamic Entries, which make up the auto-learned-node address, are aged out of the address table according to the Aging Time that you set. The Aging Time can be from 10 seconds to 1000000 seconds. A very long Aging Time can result with the outof-date Dynamic Entries that may cause incorrect packet filtering/forwarding decisions.
24-port NWay Ethernet Switch User’s Guide ♦ Automatic topology re-configuration When the path for which there is a backup path fails, the backup path will be automatically activated, and STA will automatically re-configure the network topology. STA Operation Levels STA operates on two levels: the bridge level and the port level. On the bridge level, STA calculates the Bridge Identifier for each Switch, then sets the Root Bridge and the Designated Bridges.
24-port NWay Ethernet Switch User’s Guide ♦ Bridge Priority A Bridge Priority can be from 0 to 65535. 0 is equal to the highest Bridge Priority. ♦ Bridge Hello Time The Hello Time can be from 1 to 10 seconds. This is the interval between two transmissions of BPDU packets sent by the Root Bridge to tell all other Switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
24-port NWay Ethernet Switch User’s Guide Figure 5-2. After Applying the STA Rules STA parameters Settings Effects Comment Bridge Priority lower the #, higher the priority Increases chance of becoming the Root Bridge Avoid, if the switch is used in workgroup level of a large network Hello Time 1 - 10 sec. No effect, if not Root Bridge Never set greater than Max. Age Time Max. Age Time 6 - 40 sec.
24-port NWay Ethernet Switch User’s Guide changes made to the master port are applied to all members of the trunk group. Thus, when configuring the ports in a trunk group, you only need to configure the master port. The DES-3225G supports 3 trunk groups, which may include from 2 to 8 switch ports each, except for the third trunk group which consists of the 2 ports of the Slot 1, 100BASE-TX or 100BASE-FX front-panel module.
24-port NWay Ethernet Switch User’s Guide All VLANs allow a network to be segmented in order to reduce the size of broadcast domains. All broadcast, multicast, and unknown packets entering the Switch on a particular VLAN will only be forwarded to the stations or ports (802.1Q and port-based) that are members of that VLAN. 802.1Q and port-based VLANs also limit unicast packets to members of the VLAN, thus providing a degree of security to your network. Another benefit of 802.
24-port NWay Ethernet Switch User’s Guide receive VLAN traffic, and the difference between them provides network segmentation, while still allowing resources to be shared across more than one VLAN. 802.1Q VLAN Segmentation The following example is helpful in explaining how 802.1Q VLAN segmentation works. Take a packet that is transmitted by a machine on Port 1 that is a member of VLAN 2 and has the Port VLAN ID number 2 (PVID=2).
24-port NWay Ethernet Switch User’s Guide send packets to it. Ports 1, 2 and 3 send these packets on VLAN 1 (their PVID=1), and Ports 11 and 12 send these packets on VLAN 2 (PVID=2). The third VLAN (PVID=3) is used by the server to transmit files that had been requested on VLAN 1 or 2 back to the computers. All computers that use the server will receive transmissions from it since they are all located on ports which are members of VLAN 3 (VID=3). 802.1Q VLANs Spanning Multiple Switches 802.
24-port NWay Ethernet Switch User’s Guide Figure 5-5. Data transmissions between 802.1Q-compliant Switches In the above example, step 4 is the key element. Because the packet has 802.1Q VLAN data encoded in its header, the ingress port can make VLAN-based decisions about its delivery: whether server #2 is attached to a port that is a member of VLAN 2 and thus, should the packet be delivered; the queuing priority to give to the packet, etc.
24-port NWay Ethernet Switch User’s Guide To setup port-based VLANs, simply select one of 24 VLAN ID numbers, name the VLAN and specify which ports will be members. All other ports will automatically be forbidden membership, even dynamically as a port can belong to only one VLAN. Broadcast Storms Broadcast storms are a common problem on today’s networks.
24-port NWay Ethernet Switch User’s Guide 6 U SING THE C ONSOLE I NTERFACE Your 24-port NWay Ethernet Switch supports a console management interface that allows you to set up and control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP Telnet protocol. You can use this facility to perform many basic network management functions.
24-port NWay Ethernet Switch User’s Guide Figure 6-1. Example of a console connection Connecting to the Switch Using Telnet Once you have set an IP address for your Switch, you can use a Telnet program (in a VT-100 compatible terminal mode) to access and control the Switch. Most of the screens are identical, whether accessed from the console port or from a Telnet interface. You can also use a Web-based browser to manage the Switch.

24-port NWay Ethernet Switch User’s Guide Notes about the Configuration File: This configuration file can only contain 4 settings: Code_type, Ip_addr, Subnet_mask and Default_gateway. Each command can only appear once in the configuration file. If both the Firmware Update and Use Config File options are enabled on the Update Firmware and Configuration Files screen, the Firmware Update command will take precedence and only the firmware file will be uploaded to the Switch.
