1-1 Ethernet Technology

Fast Ethernet

The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks.

A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve client/server response times. Among them, Fast Ethernet, or 100T, provides a non-disruptive, smooth evolution from 10T technology.

100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment in hardware, software, and trained personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnetworks.

Gigabit Ethernet enables fast optical fibre connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC's are able to perform 10 times the number of operations in the same amount of time.

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow's rapidly improving switching and routing internetworking technologies.

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. A switch increases capacity and decreases network loading by making it possible for a local area network to be divided into different segments, which are not competing with each other for network transmission capacity, and therefore decreasing the load on each segment.

The Switch acts as a high-speed selective bridge between the individual segments.Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the Switch, without interfering with any other segments (ports).This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the "two-repeater limit." A switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205meter network diameter limit for 100TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks.

Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and maintenance required make routers relatively impractical.Today's switches are an ideal solution to most kinds of local area network congestion problems.

Allied Telesyn AT-9724TS High-Density Layer 3 Stackable Gigabit Ethernet Switch

1-2 Switch Description

The AT-9724TS has 24 1000T Gigabit ports that may be used in uplinking various network devices to the Switch, including PCs, hubs and other switches to provide a gigabit Ethernet uplink in full-duplex mode.

In addition, the AT-9724TS is equipped with 4 SFP (Small Form Factor Portable) combo ports, which are to be used with fibre-optical transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances.These 4 SFP ports support full-duplex transmissions, have autonegotiation and can be used with AT-MG8LX10 (1000LX),AT-MG8SX (1000SX) and AT-MG8ZX (1000ZX) transceivers.These four ports are referred to as “combo” ports which means that both the SFP ports and the 1000T ports are numbered the same (21–24) and cannot be used simultaneously.Attempting to use the ports simultaneously will cause a link down status for the 1000T ports. SFP ports will always have priority over these 1000T ports.

Also included at the rear of the Switch are two 10-gigabit stacking ports used to stack up to twelve switches in a ring topology.The AT-9724TS may be used as the master unit of a switch stack when utilizing these ports and, in total, may provide a stacking solution of up to 288 gigabit ports.

Note: The four SFP combo ports on the Switch, numbered 21–24 cannot be used simultaneously with the corresponding 1000T ports, numbered 21–24. If both ports are in use at the same time (ex. port 21 of the SFP and port 21 of the 1000T), the SFP ports will take priority over the combo ports and render the 1000T ports inoperable.

	Figure 1- 3. LED Indicators
LED Description
Power	This LED will light green after the Switch is powered on to indicate the ready state of the device.The indicator is dark when the Switch is
	powered off.
Master	This LED will light solid green when the Switch is configured to be a master switch of a switch stack in a ring topology or when it is in use as a
	stand-alone switch.This LED will remain dark if the Switch is not configured to be a master switch in a switch stack.
Console	This LED should blink during the Power-On Self Test (POST).When the POST is finished successfully, the LED goes dark.This indicator will light
	solid green when the Switch is being logged into via out-of-band/local console management through the RS-232 console port in the front of the
	Switch using a straight-through serial cable.
	This LED will light solid amber if the Power-On-Self-Test has failed.
RPS	This LED will be lit when the internal power has failed and the RPS has taken over the power supply to the Switch. Otherwise, it will remain
	dark.
Port LEDs	One row of LEDs for each port is located above the ports on the front panel.The first LED is for the top port and the second one is for the
	bottom ports.A solid light denotes activity on the port while a blinking light indicates a valid link.These LEDs will remain dark if there is no
	link/activity on the port.
Stacking Ports
(SIO)	There are two LEDs in the front of the Switch marked SIO, and they relate to the two 10-gigabit stacking ports at the rear of the Switch.These
	LEDs are marked 1 and 2 and will light solid green to denote activity on the port, while a blinking light will indicate a valid link.
Stack ID	These two seven-segment LEDs display the current switch stack order of the Switch while in use. Possible numbers to be displayed range from
	1-12 in use.

1-6 Rear Panel Components

After you have successfully installed the Switch, you can configure the Switch, monitor the LED panel, and display statistics graphically using a web browser, such as Netscape Navigator (version 6.2 and higher) or Microsoft® Internet Explorer (version 5.0).

4-3 SNMP-Based Management

You can manage the Switch with an SNMP-compatible console program.The Switch supports SNMP version 1.0, version 2.0 and version 3.0.The SNMP agent decodes the incoming SNMP messages and responds to requests with MIB objects stored in the database.The SNMP agent updates the MIB objects to generate statistics and counters.

4-4 Command Line Console Interface Through The Serial Port

You can also connect a computer or terminal to the serial console port to access the Switch.The command-line-driven interface provides complete access to all Switch management features.

4-5 Connecting the Console Port (RS-232 DCE)

The Switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and configuring the Switch.This port is a female DB-9 connector, implemented as a data terminal equipment (DTE) connection.

To use the console port, you need the following equipment:

•A terminal or a computer with both a serial port and the ability to emulate a terminal.

•A null modem or crossover RS-232 cable with a female DB-9 connector for the console port on the Switch (supplied with the switch).

To connect a terminal to the console port:

1. Connect the female connector of the RS-232 cable directly to the console port on the Switch, and tighten the captive retaining screws.

2.Connect the other end of the cable to a terminal or to the serial connector of a computer running terminal emulation software. Set the terminal emulation software as follows:

3.Select the appropriate serial port (COM port 1 or COM port 2).

4.Set the data rate to 115200 baud.

5.Set the data format to 8 data bits, 1 stop bit, and no parity.

6.Set flow control to none.

7.Under Properties, select VT100 for Emulation mode.

8.Select Terminal keys for Function,Arrow, and Ctrl keys. Ensure that you select Terminal keys (not Windows keys).

Note: When you use HyperTerminal with the Microsoft® Windows® 2000 operating system, ensure that you have Windows 2000 Service Pack 2 or later installed.Windows 2000 Service Pack 2 allows you to use arrow keys in HyperTerminal's VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.

Allied Telesyn AT-9724TS High-Density Layer 3 Stackable Gigabit Ethernet Switch

9.After you have correctly set up the terminal, plug the power cable into the power receptacle on the back of the Switch.The boot sequence appears in the terminal.

10.After the boot sequence completes, the console login screen displays.

11.If you have not logged into the command line interface (CLI) program, press the Enter key at the User name and password prompts.There is one default user name and password for the Switch. User names and passwords must first be created by the administrator. If you have previously set up user accounts, log in and continue to configure the Switch.

12.Enter the commands to complete your desired tasks. Many commands require administrator-level access privileges. Read the next section for more information on setting up user accounts. See the AT-9724TS Command Line Interface Reference Manual on the documentation CD for a list of all commands and additional information on using the CLI.

13.When you have completed your tasks, exit the session with the logout command or close the emulator program.

Make sure the terminal or PC you are using to make this connection is configured to match these settings.

If you are having problems making this connection on a PC, make sure the emulation is set to VT-100.You will be able to set the emulation by clicking on the File menu in you HyperTerminal window, clicking on Properties in the drop-down menu, and then clicking the Settings tab.This is where you will find the Emulation options. If you still do not see anything, try rebooting the Switch by disconnecting its power supply.

Once connected to the console, the screen below will appear on your console screen.This is where the user will enter commands to perform all the available management functions.The Switch will prompt the user to enter a user name and a password. Upon the initial connection, there is no user name or password and therefore just press enter twice to access the command line interface.

4-6 First Time Connecting to the Switch

The Switch supports user-based security that can allow you to prevent unauthorized users from accessing the Switch or changing its settings.This section tells how to log onto the Switch.

Note: The passwords used to access the Switch are case-sensitive; therefore, "S" is not the same as "s." When you first connect to the Switch, you will be presented with the first login screen (shown below).

Note: Press Ctrl+R to refresh the screen.This command can be used at any time to force the console program in the Switch to refresh the console screen.

Figure 4- 1. Initial screen, first time connecting to the Switch

The initial username and password are:

Username: manager

Password: friend

You will be given access to the command prompt AT-9724TS:4# shown below.

Allied Telesyn AT-9724TS High-Density Layer 3 Stackable Gigabit Ethernet Switch

Figure 4- 2. Command Prompt

Note: The first user automatically gets Administrator level privileges. It is recommended to create at least one Admin-level user account for the Switch.

4-7 Password Protection

One of the first tasks when settings up the Switch is to create user accounts. If you log in using a predefined administrator-level user name, you have privileged access to the Switch's management software.

After your initial login, define new passwords for both default user names to prevent unauthorized access to the Switch, and record the passwords for future reference.

To create an administrator-level account for the Switch, do the following:

At the CLI login prompt, enter create account admin followed by the <user name> and press the Enter key.

You will be asked to provide a password.Type the <password> used for the administrator account being created and press the Enter key. You will be prompted to enter the same password again to verify it.Type the same password and press the Enter key.

Successful creation of the new administrator account will be verified by a Success message.

Note: Passwords are case sensitive. User names and passwords can be up to 15 characters in length.

The sample below illustrates a successful creation of a new administrator-level account with the user name "newmanager".

AT-9724TS:4#create account admin newmanager

Command: create account admin newmanager

Enter a case-sensitive new password:********

Enter the new password again for confirmation:********

Success.

AT-9724TS:4#

mCaution: CLI configuration commands only modify the running configuration file and are not saved when the Switch is rebooted.To save all your configuration changes in nonvolatile storage, you must use the save command to copy the running configuration file to the startup configuration.

4-8 SNMP Settings

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group or network.

Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device.A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device.These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network.

Allied Telesyn AT-9724TS High-Density Layer 3 Stackable Gigabit Ethernet Switch

The AT-9724TS supports SNMP versions 1, 2c, and 3.You can specify which version of SNMP you want to use to monitor and control the Switch.The three versions of SNMP vary in the level of security provided between the management station and the network device.

In SNMP v.1 and v.2, user authentication is accomplished using 'community strings', which function like passwords.The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been authenticated are ignored (dropped).

The default community strings for the Switch used for SNMP v.1 and v.2 management access are: public – Allows authorized management stations to retrieve MIB objects.

private – Allows authorized management stations to retrieve and modify MIB objects.

SNMP v.3 uses a more sophisticated authentication process that is separated into two parts.The first part is to maintain a list of users and their attributes that are allowed to act as SNMP managers.The second part describes what each user on that list can do as an SNMP manager.

The Switch allows groups of users to be listed and configured with a shared set of privileges.The SNMP version may also be set for a listed group of SNMP managers.Thus, you may create a group of SNMP managers that are allowed to view read-only information or receive traps using SNMP v.1 while assigning a higher level of security to another group, granting read/write privileges using SNMP v.3.

Using SNMP v.3 individual users or groups of SNMP managers can be allowed to perform or be restricted from performing specific SNMP management functions.The functions allowed or restricted are defined using the Object Identifier (OID) associated with a specific MIB.An additional layer of security is available for SNMP v.3 in that SNMP messages may be encrypted.To read more about how to configure SNMP v.3 settings for the Switch read the section entitled Management.

Traps

Traps are messages that alert network personnel of events that occur on the Switch.The events can be as serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change.The Switch generates traps and sends them to the trap recipient (or network manager).Typical traps include trap messages for Authentication Failure,Topology Change and Broadcast/Multicast Storm.

MIBs

Management and counter information are stored by the Switch in the Management Information Base (MIB).The Switch uses the standard MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved from any SNMP-based network management software. In addition to the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended Management Information Base.The proprietary MIB may also be retrieved by specifying the MIB Object Identifier. MIB values can be either read-only or read-write.

4-9 IP Address Assignment

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP,TFTP).The Switch's default IP address is 10.0.0.1.You can change the default Switch IP address to meet the specification of your networking address scheme.

The Switch is also assigned a unique MAC address by the factory.This MAC address cannot be changed, and can be found by entering the command "show switch" into the command line interface, as shown below.

Figure 4- 3.“show switch” command

The Switch's MAC address can also be found from the Web management program on the Switch Information (Basic Settings) window in the

Configuration menu.

The IP address for the Switch must be set before it can be managed with the Web-based manager.The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy.Where the x's represent the IP address to be assigned to the IP interface named System and the y's represent the corresponding subnet mask.

Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z.Where the x's represent the IP address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a management station to the Switch's Telnet or Web-based management agent.

Figure 4- 4.Assigning the Switch an IP Address

In the above example, the Switch was assigned an IP address of 10.53.13.144 with a subnet mask of 255.0.0.0.The system message Success indicates that the command was executed successfully.The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management.

4-10 Connecting Devices to the Switch

After you assign IP addresses to the Switch, you can connect devices to the Switch.

To connect a device to an SFP transceiver port:

•Use your cabling requirements to select an appropriate SFP transceiver type.

•Insert the SFP transceiver (sold separately) into the SFP transceiver slot.

•Use the appropriate network cabling to connect a device to the connectors on the SFP transceiver.

m Caution: When the SFP transceiver acquires a link, the associated integrated 10/100/1000T port is disabled.

5-1 Introduction

All software functions of the AT-9724TS can be managed, configured and monitored via the embedded web-based (HTML) interface.The Switch can be managed from remote stations anywhere on the network through a standard browser such as Netscape Navigator/Communicator or Microsoft Internet Explorer.The browser acts as a universal access tool and can communicate directly with the Switch using the HTTP protocol.

The Web-based management module and the Console program (and Telnet) are different ways to access the same internal switching software and configure it. Thus, all settings encountered in web-based management are the same as those found in the console program.

5-2 Login to Web Manager

To begin managing your Switch, simply run the browser you have installed on your computer and point it to the IP address you have defined for the device.The URL in the address bar should read something like: http://123.123.123.123, where the numbers 123 represent the IP address of the Switch.

Note: The Factory default IP address for the Switch is 10.0.0.1.

6-2 IP Address

The IP Address may initially be set using the console interface prior to connecting to it through the Ethernet. If the Switch IP address has not yet been changed, read the introduction of the AT-9724TS Command Line Interface Reference Manual or return to Chapter 4 of this manual for more information.

To change IP settings using the web manager you must access the IP Address menu located in the Configuration folder.

To configure the Switch's IP address:

Open the Configuration folder and click the IP Address menu link.The web manager will display the Switch's current IP settings in the IP configuration menu, as seen below.

Figure 6- 2. IP Address Settings window

To manually assign the Switch's IP address, subnet mask, and default gateway address:

1.Select Manual from the Get IP From drop-down menu.

2.Enter the appropriate IP Address and Subnet Mask.

3.If you want to access the Switch from a different subnet from the one it is installed on, enter the IP address of the Default Gateway. If you will manage the Switch from the subnet on which it is installed, you can leave the default address (0.0.0.0) in this field.

4.	If no VLANs have been previously configured on the Switch, you can use the default VLAN Name.The default VLAN contains all of the Switch ports
	as members. If VLANs have been previously configured on the Switch, you will need to enter the VLAN ID of the VLAN that contains the port
	connected to the management station that will access the Switch.The Switch will allow management access from stations with the same VID listed
	here.

Note: The Switch's factory default IP address is 10.0.0.1 with a subnet mask of 255.0.0.0 and a default gateway of 0.0.0.0.

To use the BOOTP or DHCP protocols to assign the Switch an IP address, subnet mask, and default gateway address:

Use the Get IP From: <Manual> pull-down menu to choose from BOOTP or DHCP.This selects how the Switch will be assigned an IP address on the next reboot.

The IP Address Settings options are:

Parameter	Description

BOOTP	The Switch will send out a BOOTP broadcast request when it is powered up.The BOOTP protocol allows IP
	addresses, network masks, and default gateways to be assigned by a central BOOTP server. If this option is set,
	the Switch will first look for a BOOTP server to provide it with this information before using the default or
	previously entered settings.
DHCP	The Switch will send out a DHCP broadcast request when it is powered up.The DHCP protocol allows IP
	addresses, network masks, and default gateways to be assigned by a DHCP server. If this option is set, the
	Switch will first look for a DHCP server to provide it with this information before using the default or
	previously entered settings.
Manual	Allows the entry of an IP address, Subnet Mask, and a Default Gateway for the Switch.These fields should be of
	the form xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal form) between 0 and 255.This
	address should be a unique address on the network assigned for use by the network administrator.
Subnet Mask A	Bitmask that determines the extent of the subnet that the Switch is on. Should be of the form
	xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal) between 0 and 255.The value
	should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and 255.255.255.0 for a Class C
	network, but custom subnet masks are allowed.
Default Gateway	IP address that determines where packets with a destination address outside the current subnet should be
	sent.This is usually the address of a router or a host acting as an IP gateway. If your network is not part of an
	intranet, or you do not want the Switch to be accessible outside your local network, you can leave this field
	unchanged.
