Chapter 1

Overview

The AT-8324SX Fast Ethernet Switch is a stackable switch with 24 10Base-T/100Base-TX ports, plus two slots for optional 100Base-FX, 1000Base-SX, and 1000Base-LX expansion modules. One of these slots can also be used for the optional AT-BSTACK1 Stacking Module that allows you attach up to four switches to a 4 Gbps high-speed backplane. There is also an expansion slot for the AT-BMGMT module, an SNMP-based network management module. This module supports both in-band and out-of-band access for managing the switch and the attached stack.

Options

The AT-8324SX switch employs a high-speed switching fabric. This design allows for simultaneous transport of multiple packets at low latency on all ports. It also uses store-and-forward switching to ensure maximum data integrity. In this mode, the entire packet must be received into a port buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

This AT-8324SX switch can be used in a standalone configuration, or can be stacked up to four high to form a single logical switch with up to 104 ports. When stacked, the 4 Gbps stack backplane provides enough bandwidth for the most demanding environment. Moreover, you can use a 100 Mbps fiber module for connecting to a remote site, or a Gigabit module for a high-speed backbone connection.

This switch contains a comprehensive array of LEDs for "at-a-glance" monitoring of network and port status. The optional AT-BMGMT Management Module allows the entire stack to be managed in-band via SNMP, RMON (Groups 1, 2, 3 and 9), or with a Web browser, as well as remotely via Telnet or SLIP. This module also has a serial port for out-ofband management.

There’s also support for the AT-BRPS8000 Redundant Power Supply to ensure continuous operation in the event of an AC power loss or the failure of the switch’s internal power supply.

Overview

How to Use this Guide

Read Chapters 1 through 4 before installing the AT-8324SX switch. You can also read the how to manage your network. This guide is available from the Allied Telesyn web site.

10Base-T/

100Base-TX Ports

Status LEDs

These ports are dual-speed RJ-45 ports with built-in wiring crossovers (MDI-X). Workstations and servers can be connected to these ports with straight-through cable. When connecting to another switch or a hub, you can connect to a port on the attached device that does not have built-in wiring crossovers (MDI) or use crossover cabling (see Appendix A for a pin-out description of crossover cable).

Each of these ports support auto-negotiation, so the optimum transmission mode (half- or full-duplex) and data rate (10 or 100 Mbps) are selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually.

The LEDs, which are located on the front panel for easy viewing, are described in the following table.

(Continued)

The top expansion slot on the rear panel of the switch is for the optional AT-BMGMT Management Module (Figure 3). This module can manage the switch or the attached stack. It offers a variety of management options, including SNMP, RMON and a Web-based interface. This module also includes an RS-232 port for out-of-band management. This is an RS-232 serial port with a DB-9 connector. A PC may be connected to this port for configuration and monitoring purposes out-of band via a full-handshaking null modem cable. You can also make a remote connection to this port via modems. This allows you to access the out-of-band interface, or to establish a network connection using SLIP protocol. (See Appendix A for a description of wiring options.)

Figure 3

Optional AT-BMGMT Management Module

AT-8324SX Installation Guide

The module provides a wide range of advanced performance-enhancing features. Port-based and tagged VLANs, plus support for automatic GVRP VLAN registration provide traffic security and efficient use of network bandwidth. QoS priority queueing ensures the minimum delay for moving real-time multi-media data across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. And broadcast storm control prevents broadcast traffic storms from engulfing the network. Some of the management features are described below. For a detailed description, refer to the

Management Software User’s Guide

, which is available from the Allied

AT-S29

Telesyn web site.

Spanning Tree Protocol

The AT-8324SX Fast Ethernet Switch supports ANSI/IEEE 802.1d Spanning Tree Protocol (STP). This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, the protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should fail for any reason, an alternate path will be activated to maintain the connection.

The default setting for the STP is "enabled." This protocol may be configured (enabled or disabled) out-of-band via the serial console port or in-band via the Web interface, Telnet, or SNMP network management software.

VLANs

The AT-8324SX switch supports up to 16 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. By segmenting your network into VLANs, you can:

Eliminate broadcast storms which severly degrade performance

in a flat network.

Simplify network management for node changes/moves by

remotely configuring VLAN membership for the concerned port, rather than having to manually change the node’s IP address.

Provide data security by restricting all traffic to the originating

VLAN, except where a connection has been configured between separate VLANs using a router or Layer 3 switch.

Overview

Traffic Priority

The switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using two distinct categories with Weighted Fair Queuing. It uses IEEE 802.1Q and 802.1p tags to prioritize incomming traffic based on input from the end-station application driver. These functions can be used, for example, to provide independent priorities for real-time video, real-time voice, guaranteeddelivery data, or best-effort data.
