Stackable NWay Ethernet Switch User’s Guide 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.
Features The DES-3624 series of Switches can include one master (DES-3624I, DES-3624iF, or DES-3624iFM) and up to three clients (DES-3624, DES-3624F, or DES-3624FM). They are designed for easy installation and high performance in an environment where traffic on the network and the number of users increases continuously.

Switch installed on a Desktop or Shelf Rack Installation The Switch can be mounted in an EIA standard size, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets on the Switch’s side panels (one on each side) and secure them with the screws provided.
Stackable NWay Ethernet Switch User’s Guide Power On The Switch can be used with AC power sources 100 - 240 VAC, 50 - 60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The Switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.
2-port TX, 2-port FX (MT-RJ), or 1-port FX (SC). ♦ One or two MDI-II uplink jacks are supported. Port numbers 1 and 2 on the DES-3624, DES-3624F, and DES-3624FM are equipped with MDI-X jacks for normal end-node connections and MDI-II jacks for uplink connections.
Stackable NWay Ethernet Switch User’s Guide Rear Panel The rear panel of the DES-3624, DES-3624F, and DES-3624FM consist of a slot (labeled Slot2) for a Stacking input/output port and an AC power connector. The rear panel of the DES-3624i, DES-3624iF, and DES- 3624iFM consist of two slots (labeled Slot2 and Slot3).
The DES-3624i, DES-3624iF, and DES-3624iFM are all intelligent Switches capable of acting as a master for up to three slave Switches (DES-3624, DES-3624F, or DES-3624FM). Each port is referred to by unit ID and port number in your DES-3624 Series stack.

Configuring the Switch to implement these concepts is discussed in detail in the next chapters.
Stackable 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.
Stackable 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.
Stackable 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.

Stackable NWay Ethernet Switch User’s Guide Port Trunking Port trunking is used to combine a number of ports together to make a single high-bandwidth data pipeline. The participating parts are called members of a trunk group, with one port designated as the anchor of the group.
Stackable NWay Ethernet Switch User’s Guide setup on your network and configure the Switch accordingly. 802.1Q VLANs support IEEE 802.1Q tagging, which enables them to span the entire network (assuming all switches on the network are IEEE 802.1Q- compliant). In contrast, MAC-based broadcast domains are limited to the Switch and devices directly connected to them.
Stackable NWay Ethernet Switch User’s Guide There are two key components to understanding 802.1Q VLANs: Port VLAN ID numbers (PVIDs) and VLAN ID numbers (VIDs). Both variables are assigned to a switch port, but there are important differences between them. A user can only assign one PVID to each switch port. The PVID defines which VLAN a packet belongs to when packets need to be forwarded to another switch port or somewhere else on the network.
Stackable NWay Ethernet Switch User’s Guide 7,11,12 1,2,3,7,11,12 Table 5-2. VLAN assignments for Figure 5-4 The server attached to Port 7 is shared by VLAN 1 and VLAN 2 because Port 7 is a member of both VLANs (it is listed as a member of VID 1 and 2). Since it can receive packets from both VLANs, all ports can successfully send packets to it to be printed.
Stackable 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;...
However, with the advent of VLANs, switches are now able to limit broadcast domains better and cheaper than routers. Also, many switches, including the DES-3624 Series, have broadcast sensors and filters built into each port to further control broadcast storms.
Stackable NWay Ethernet Switch User’s Guide SING THE ONSOLE NTERFACE Your Stackable 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.
Stackable 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.

Stackable NWay Ethernet Switch User’s Guide ♦ Lock Address Table Mostly used for security purposes, when the forwarding table is locked the Switch will no longer learn the MAC addresses for new hosts. If your network configuration doesn’t change, locking the forwarding table helps keep intruders off your network since any packet coming from an unknown source address will be dropped by the Switch.

Stackable NWay Ethernet Switch User’s Guide AMPLE ONFIGURATION This appendix provides a sample configuration file that can be used with the Update Firmware and Configuration Files screen in the console program. The configuration file is a simple text file that you create. It has two functions: to point to the location of a file on a TFTP server, and to set the IP address, subnet mask and default gateway for the Switch.
Stackable 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 Default_gateway Each command can only appear once in the configuration file. If both the Firmware Update and Use Config File options are enabled, the Firmware Update command will take precedence and only the firmware file will be uploaded to the switch.
