Product Description AC Power Connector Systems # All models Description The switch has a single AC power supply socket on the back panel, which has autoswitch AC inputs. Refer to Appendix A, Technical Specifications, for the input voltage range. To power ON or OFF the switch, you connect or disconnect the power cord.
AT-8000 Series Fast Ethernet Switches Installation Guide Software Features The following sections describe these software features: # AT-S39 Management Software # Enhanced Stacking # Spanning Tree Protocol (STP) # Tagged and Port-based Virtual LANs (VLANs) # Basic VLAN Mode # Quality of Service # BOOTP and Dynamic Host Configuration Protocol (DHCP) # Port Mirroring # Port Trunking # Port Security Note All of the features described here are further described in the AT-S39 Management Software User’s Guide.
Product Description You can access the switch’s management software four ways: # RS-232 Terminal Port # Web Browser # Telnet Application Protocol # SNMP management program RS-232 Terminal Port One method for accessing the management software is by connecting a terminal or a PC with a terminal emulation program to the RS-232 Terminal Port on the switch. This is commonly referred to as local or outof-band management. (Refer to Figure 13.
AT-8000 Series Fast Ethernet Switches Installation Guide Web-browser You can also manage the switch from a workstation on your network using a web browser, such as Netscape Navigator. This is referred to as remote or in-band management. To start a web browser management session, you simply enter the switch’s IP address in the URL field of the web browser, as shown in Figure 14. URL Field with Switch IP Address Figure 14 URL Field of a Web Browser Figure 15 shows the AT-S39 management software’s home page.
Product Description Telnet Application Protocol The Telnet application protocol offers another way for you to remotely manage a switch from a workstation on your network. Starting this type of remote access requires that you specify the IP address of the switch in the Telnet protocol. This method of managing the switch will work only after you have assigned the switch an IP address and subnet mask or have implemented the enhanced stacking feature.
AT-8000 Series Fast Ethernet Switches Installation Guide Enhanced Stacking This feature is designed to simplify network management. You can use the feature to manage all the AT-8000 Series Fast Ethernet Switches that reside in a subnet on your network from just one management session. Before the advent of enhanced stacking, managing a switch meant that you had to establish a separate management session with it.
Product Description # For purposes of redundancy, it is probably a good idea to assign IP addresses to two switches in each subnet. In this way, should you need to remove one switch with an IP address from a subnet, such as for maintenance, the second switch will still be available for you to remotely manage your Fast Ethernet switches. Figure 16 illustrates the enhanced stacking feature. The figure illustrates a network consisting of two subnets.
AT-8000 Series Fast Ethernet Switches Installation Guide Spanning Tree Protocol (STP) The AT-8000 Series Fast Ethernet Switches are IEEE 802.1D standardcompliant and support the spanning tree protocol. STP can be an important part of large networks where loops exist in the network topology. A loop occurs when two or more nodes on your network can transmit data to each other over more than one link.
Product Description Tagged and Port-based VLANs A VLAN is a group of end nodes that form an independent subnetwork. Each VLAN constitutes a separate broadcast domain, where the frames of a VLAN are not allowed to cross the VLAN boundary. VLANs can be extremely useful in improving network performance and increasing network security. You can create VLANs to group the workstations, servers, and other networking equipment connected to your switches into logical workgroups.
AT-8000 Series Fast Ethernet Switches Installation Guide Quality of Service (QOS) The AT-8000 Series Fast Ethernet Switches support the IEEE 802.1p standard and Quality of Service. QoS can be important in network environments where there are time-critical applications, such as voice transmission or video conferencing, that can be adversely affected by packet transfer delays. Prior to QoS, network traffic was handled in a best-effort manner.
Product Description Port Mirroring The port mirroring feature allows you to unobtrusively monitor the traffic being received and transmitted on a port on a switch by having the traffic copied to another switch port. You can connect a network analyzer to the port functioning as the mirror port to monitor the traffic without impacting network performance or speed. Port Trunking Port trunking is an economical way for you to increase the bandwidth between two Ethernet switches.
AT-8000 Series Fast Ethernet Switches Installation Guide # You can create a port trunk of the GBIC modules installed in the Port A and Port B slots of an AT-8024GB Switch, provided that the GBIC modules are of the same medium type. # You can create a port trunk using the two fiber optic ports in an AT-8026FC Switch. # The ports on the end node must also be configured as a port trunk.
Product Description Port Security The AT-8000 Series Fast Ethernet Switches have three levels of port security: Limited, Secure, and Lock All Ports. You can use the port security levels to enhance the security to your network. The security levels are briefly described below. For further information and instructions on activating a security level, refer to the AT-S39 Management Software User’s Guide.
AT-8000 Series Fast Ethernet Switches Installation Guide A Few Basics to Ethernet Switching An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
Product Description Duplex Mode Duplex mode refers to how an end node receives and transmits data. If an end node can receive or transmit data, but not both simultaneously, the end node is operating in what is referred to as half-duplex mode. If an end node can both receive and transmit data simultaneously, the node is said to be operating in full-duplex mode. Naturally, a node capable of operating in full-duplex can handle data much faster than a node that can only operate in half-duplex mode.
AT-8000 Series Fast Ethernet Switches Installation Guide How a switch signals an end node to stop transmitting data differs depending on the speed and duplex mode of the end node and switch port. A twisted pair port operating at 100 Mbps port and half-duplex mode stops an end node from transmitting data by forcing a collision. A collision on an Ethernet network occurs when two nodes attempt to transmit data using the same data link at the same time. A collision causes end nodes to stop sending data.
Product Description Network Topologies This section illustrates several of the network topologies you can create with the AT-8000 Series Fast Ethernet Switches. Power Workgroup Topology The topology shown in Figure 18 is commonly referred to as a power workgroup topology. Each workstation or node is connected directly to a port on an AT-8024 Fast Ethernet Switch. Each node has a dedicated data link to the switch for best performance and reliability. The devices can operate at either 10 Mbps or 100 Mbps.
AT-8000 Series Fast Ethernet Switches Installation Guide Collapsed Backbone - Hub Topology In the topology illustrated in Figure 19, an AT-8024 connects together 10/100 Mbps Ethernet hubs. This type of topology is often referred to as a collapsed backbone topology. The switch functions as the focal point of the network by acting as a bridge between the different workgroups.
Product Description Mixed Topology You can always combine topologies as well as build a larger network by connecting different switches together. If the switches are within 100 meters of each other, you can use the twisted pair ports. If the switches are further apart, then you will need to use fiber optic ports. Figure 20 illustrates a network of three AT-8026FC Fast Ethernet Switches. The workstations and servers of the network are connected either directly to a switch or through an Ethernet hub.
AT-8000 Series Fast Ethernet Switches Installation Guide Collapsed Backbone Switch Topology If you need to connect together multiple switches and the switches are physically separated by more than 2 kilometers, or if you want to build a 1000 Mbps backbone network between switches, you can use AT-8024GB Fast Ethernet Switches and install fiber optic GBIC modules. The modules span large distances and, with an operating speed of 1000 Mbps, can provide a fast backbone between the switches.
