AT-8350GB Installation Guide Software Features The following sections describe these software features: ❑ AT-S41 Management Software ❑ Spanning Tree Protocol (STP) ❑ Port-based and Tagged Virtual LANs (VLANs) ❑ Quality of Service ❑ IGMP Snooping ❑ Dynamic Host Configuration Protocol (DHCP) ❑ Port Monitoring ❑ Port Trunking ❑ Port Security Note All of the features described here are further described in the AT-S41 Management Software User’s Guide for the AT-8350 Switch.
Product Description ❑ 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, as indicated in Figure 21. This is commonly referred to as local or out-of-band management. Please refer to Starting a Local Management Session on page 78 for instructions on how to start a local management session.
AT-8350GB Installation Guide Web Browser You can also manage the switch from a workstation on your network using a web browser, such as Internet Explorer. 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 23. To manage an AT-8350GB switch stack, enter the IP address of the master switch of the stack.
Product Description Telnet Application Protocol Using the Telnet application protocol is another way for you to manage the switch remotely 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. SNMP Management You can also manage a switch with an SNMP management program, such as HP Openview. This management method requires loading the AT-8350GB Fast Ethernet Switch MIBs into the SNMP management program.
AT-8350GB Installation Guide Port-based and Tagged 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.
Product Description The QoS feature was designed to address this problem. With it, Ethernet frames can be assigned different priorities. The switch uses the priorities when determining which frames to forward first. Frames from endnodes running time-critical applications can be given a high priority, so that they will be forwarded by the switch ahead of less time-critical frames.
AT-8350GB Installation Guide Dynamic Host Configuration Protocol (DHCP) This application protocol was developed to simplify network management. It is used to automatically assign IP configuration information to the devices on your network, such as an IP address, subnet mask, and, in some instances, a default gateway address. The AT-8350GB Fast Ethernet Switch supports this protocol and can obtain its IP configuration information from a DHCP server on your network.
Product Description Below are the guidelines to follow when planning a port trunk: ❑ The switch can support up to four port trunks at a time. ❑ A port trunk can consist of up to four 10/100 Mbps twisted pair ports or two gigabit ports. ❑ The duplex mode, speed, and flow control settings must be the same for all of the ports in a trunk. ❑ When cabling a trunk, the order of the connections should be maintained on both nodes.
AT-8350GB Installation Guide Example of a Port Trunk You can use port trunking to increase the bandwidth between switches. The example in Figure 25 shows a port trunk of four data links between two AT-8350GB Fast Ethernet switches.
Product Description Port Security The AT-8350GB Fast Ethernet switch has three levels of port security: Normal (default), Limited, and Secure. 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-S41 Management Software User’s Guide for the AT-8350GB Switch.
AT-8350GB 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 If the switch receives a packet with a destination address that is on the same port on which the packet was received, it discards the packet without forwarding it on to any port. Since both the source node and the destination node for the packet are located on the same port on the switch, there is no reason for the switch to forward the packet. Duplex Mode Duplex mode refers to how an end node receives and transmits data.
AT-8350GB Installation Guide between the nodes, might need to instruct the faster end node to stop transmitting data to allow the slower end node to catch up. An example of this would be when a server operating at 100 Mbps is sending data to a workstation operating at only 10 Mbps. 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.
Product Description Network Topologies This section illustrates several of the network topologies you can create with the AT-8350GB Fast Ethernet switch. Power Workgroup Topology The topology shown in Figure 26 is commonly referred to as a power workgroup topology. Each workstation or node is connected directly to a port on an AT-8350GB Fast Ethernet switch, giving each node a dedicated data link to the switch for best performance and reliability. The devices can operate at either 10 Mbps or 100 Mbps.
AT-8350GB Installation Guide Collapsed Backbone - Hub Topology In the topology illustrated in Figure 27, an AT-8350GB Fast Ethernet switch is used to connect 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 for all workgroup hubs in your network by acting as a bridge between the different workgroups.
Product Description Switch Stacking Topology A switch stack creates a powerful logical switch by allowing two or more individual switches to function as one unit. Switch stacks can simplify network management because you can manage the switches as a unit, rather than individually. The network topology in Figure 22 includes several examples of AT-8350GB switch stacks.
