CHAPTER 1

Getting to Know Your Switch

This chapter introduces the main features and applications of the Switch.

1.1 Introduction

The MGS3700-12C is a layer 2 stand-alone Gigabit Ethernet (GbE) switch.
The Switch has 12 GbE dual personality interfaces with each interface comprising one mini-GBIC slot and one 100/1000 Mbps RJ-45 port, with either port or slot active at a time.
With its built-in web configurator, managing and configuring the Switch is easy. In addition, the Switch can also be managed via Telnet, any terminal emulator program on the console port, or third-party SNMP management.
This section shows a few examples of using the Switch in various network environments.
See Chapter 47 on page 419 for a full list of software features available on the Switch.
1.1.1 Backbone Application
The Switch is an ideal solution for small networks where rapid growth can be expected in the near future. The Switch can be used standalone for a group of heavy traffic users. You can connect computers and servers directly to the Switch’s port or connect other switches to the Switch.
MGS3700-12C User’s Guide
25
Page 26
Chapter 1 Getting to Know Your Switch
In this example, all computers can share high-speed applications on the server. To expand the network, simply add more networking devices such as switches, routers, computers, print servers etc.
Figure 1 Backbone Application
1.1.2 Bridging Example
In this example application the Switch connects different company departments (RD and Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the Switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the Switch.
Moreover, the Switch eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location.
Figure 2 Bridging Application
26
MGS3700-12C User’s Guide
Page 27
Chapter 1 Getting to Know Your Switch
1.1.3 High Performance Switching Example
The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks.
Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance. The Switch can provide the same bandwidth as ATM at much lower cost while still being able to use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely communicate with each other.
Figure 3 High Performance Switched Workgroup Application
1.1.4 IEEE 802.1Q VLAN Application Examples
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router.
For more information on VLANs, refer to Chapter 9 on page 117.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain thus increase network performance through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re­cabling.
MGS3700-12C User’s Guide
27
Page 28
Chapter 1 Getting to Know Your Switch
Shared resources such as a server can be used by all ports in the same VLAN as the server. In the following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to other VLAN groups too.
Figure 4 Shared Server Using VLAN Example

1.2 IPv6 Support

IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10 supports the following features.
• Static address assignment and stateless auto-configuration
• Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)
• Remote Management using ping SNMP, telnet, HTTP and FTP services
• ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such as “ping”
• IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time
• DHCPv6 client and relay
• Multicast Listener Discovery (MLD) snooping and proxy
For more information on IPv6, refer to the CLI Reference Guide.

1.3 Ways to Manage the Switch

Use any of the following methods to manage the Switch.
28
MGS3700-12C User’s Guide
Page 29
Chapter 1 Getting to Know Your Switch
• Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser. See Chapter 4 on page 47.
• Command Line Interface. Line commands offer an alternative to the web configurator and in some cases are necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use FTP for firmware upgrades and configuration backup/restore. See
Section 38.8 on page 363.
• SNMP. The Switch can be monitored by an SNMP manager. See Section 39.3 on
page 368.
• Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 42 on
page 395.

1.4 Good Habits for Managing the Switch

Do the following things regularly to make the Switch more secure and to manage the Switch more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.v3.91(AAFX.0)
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration.

CHAPTER 2
Hardware Installation and
Connection
This chapter shows you how to install and connect the Switch.

2.1 Installation Scenarios

The Switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop installation and the brackets in a rack-mounted installation.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front
and 3.4 inches (8 cm) at the back of the Switch. This is especially important for enclosed rack installations.

2.2 Desktop Installation Procedure

1 Make sure the Switch is clean and dry.
2 Set the Switch on a smooth, level surface strong enough to support the weight of
the Switch and the connected cables. Make sure there is a power outlet nearby.
3 Make sure there is enough clearance around the Switch to allow air circulation and
the attachment of cables and the power cord.
4 Remove the adhesive backing from the rubber feet.
MGS3700-12C User’s Guide

Page 32
Chapter 2 Hardware Installation and Connection
5 Attach the rubber feet to each corner on the bottom of the Switch. These rubber
feet help protect the Switch from shock or vibration and ensure space between devices when stacking.
Figure 5 Attaching Rubber Feet
Note: Do NOT block the ventilation holes. Leave space between devices when
stacking.

2.3 Mounting the Switch on a Rack

The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your Switch on a standard EIA rack using a rack-mounting kit.
2.3.1 Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
Failure to use the proper screws may damage the unit.
2.3.1.1 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains.
• Make sure the position of the Switch does not make the rack unstable or top­heavy. Take all necessary precautions to anchor the rack securely before installing the unit.

equipment.
Connect the signal output pins to a signal input terminal on another piece of equipment.
See Chapter 47 on page 419 for details on the pin assignments required.
3.1.1 Console Port
For local management, you can use a computer with terminal emulation software configured to the following parameters:
• VT100
• Terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer.
3.1.2 Gigabit Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Fast Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and the duplex mode can be half duplex or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight­through or crossover Ethernet cable.
36
Four of the 1000Base-T Ethernet ports are paired with a mini-GBIC slot to create a dual personality interface. The Switch uses up to one connection for each mini­GBIC and 1000Base-T Ethernet pair. The mini-GBIC slots have priority over the Gigabit ports. This means that if a mini-GBIC slot and the corresponding GbE port are connected at the same time, the GbE port will be disabled.
MGS3700-12C User’s Guide
Page 37
When auto-negotiation is turned on, a Ethernet port negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.
3.1.2.1 Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
•Link Aggregation: Disabled
Chapter 3 Hardware Overview
3.1.2.2 Auto-crossover
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you may use either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port connections. Auto-crossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can connect both computers and switches/hubs.
3.1.3 Mini-GBIC Slots
These are slots for mini-GBIC (Gigabit Interface Converter) transceivers. A transceiver is a single unit that houses a transmitter and a receiver. The Switch does not come with transceivers. You must use transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.
To avoid possible eye injury, do not look into an operating fiber­optic module’s connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)

Chapter 3 Hardware Overview
3.1.4 Management Port
The MGMT (management) port is used for local management. Connect directly to this port using an Ethernet cable. You can configure the Switch via Telnet or the web configurator.
The default IP address of the management port is 192.168.0.1 with a subnet mask of 255.255.255.0.
3.1.5 Power Connector
Make sure you are using the correct power source as shown on the panel and that no objects obstruct the airflow of the fans.
Use the following procedures to connect the Switch to a power source after you have installed it.
Note: Check the power supply requirements in Chapter 47 on page 419, and make
sure you are using an appropriate power source.
Keep the power supply switch and the Switch’s power switch in the OFF position until you come to the procedure for turning on the power.
MGS3700-12C User’s Guide
39
Page 40
Chapter 3 Hardware Overview
Use only power wires of the required diameter for connecting the Switch to a power supply.
3.1.5.1 AC Power Connection
Connect the female end of the power cord to the power socket of your Switch. Connect the other end of the cord to a power outlet.
3.1.5.2 DC Power Connection
The Switch uses a single ETB series terminal block plug with four pins which allows you to connect up to two separate power supplies. If one power supply fails the system can operate on the remaining power supply. Use two wires to connect to a single terminal pair, one wire for the positive terminal and one wire for the negative terminal.
Note: The current rating of the power wires must be greater than 20 Amp s. The power
supply to which the Switch connects must have a built-in circuit breaker or switch to toggle the power.
Note: When installing the power wire, push it wire firmly into the terminal as deep as
possible and make sure that no exposed (bare) wire can be seen or touched.
Exposed power wire is dangerous. Use extreme care when connecting a DC power source to the device.
To connect a power supply:
1 Use a screwdriver to loosen the terminal block captive screws.
2 Connect one end of a power wire to the Switch’s RTN (return) pin and tighten the
captive screw.
3 Connect the other end of the power wire to the positive terminal on the power
supply.
4 Connect one end of a power wire to the Switch’s -48V (input) pin and tighten the
captive screw.
5 Connect the other end of the power wire to the negative terminal on the power
supply.

3.1.6 Signal Slot
The Signal slot (fitted with the signal connector) allows you to connect devices to the Switch, such as sensors or other ZyXEL switches which support the external alarm feature. This feature is in addition to the system alarm, which detects abnormal temperatures, voltage levels and fan speeds on the Switch.
Your Switch can respond to an external signal in four ways.
•The ALM LED shows an alert.
•The Signal slot can send an external alarm on to another device. By daisy-
chaining the signal sensor cables from one Switch to another ZyXEL switch which supports this feature, the external alarm alert (but not the system alarm) is received on each Switch.
• The Switch can also be configured to send an SNMP trap to the SNMP server. See Section 39.3 on page 368 for more information on using SNMP.
• The Switch can be configured to create an error log of the alarm. See Section
41.1 on page 391 for more information on using the system log.
Chapter 3 Hardware Overview
3.1.6.1 Connect a Sensor to the Signal Slot
This section shows you how to connect an external sensor device to the Switch.
1 Use a connector to connect wires of the correct gauge to the sensor’s signal
output pins. See Chapter 47 on page 419 for the wire specifications. Check the sensor’s documentation to identify its two signal output pins.
2 Connect these two wires to any one of the following pairs of signal input pins on
the Switch’s Signal connector - (4,5) (6,7) (8,9) (10,11). The pin numbers run from the right side of the connector to the left.
2a Connect each of the sensor’s two signal output wires to the Signal connector
by depressing the spring clip corresponding to the pin you are connecting to.
2b Insert the wire and release the spring clip.
2c Repeat the process for the sensor’s other signal output wire. A total of four
sensors may be connected to the Signal connector in this way using the remaining signal input pins.

You can also daisy-chain the external alarm to another ZyXEL Switch which supports the external alarm feature. If daisy-chaining to a ZyXEL switch that is a different model, check your switch’s documentation for the correct pin assignments.
1 Use wires of the correct gauge to connect either of the signal output pin pairs (1-
normal close, 2-common) or (2-common, 3-normal open) on the Signal connector to the input signal pin pairs of an Signal connector on another ZyXEL
Switch.

Initial Setup Example

This chapter shows how to set up the Switch for an example network.

5.1 Overview

The following lists the configuration steps for the initial setup:
• Create a VLAN
• Set port VLAN ID
• Configure the Switch IP management address
5.1.1 Creating a VLAN
VLANs confine broadcast frames to the VLAN group in which the port(s) belongs. You can do this with port-based VLAN or tagged static VLAN with fixed port members.
In this example, you want to configure port 1 as a member of VLAN 2.
Figure 22 Initial Setup Network Example: VLAN

2 In the Static VLAN screen,
select ACTIVE, enter a descriptive name in the Name field and enter 2 in the VLAN Group ID field for the VLAN2 network.
Note: The VLAN Group ID field in this screen and the VID field in the IP Setup
screen refer to the same VLAN ID.
3 Since the VLAN2 network is connected to port 1 on the Switch, select Fixed to
configure port 1 to be a permanent member of the VLAN only.
4 To ensure that VLAN-unaware devices (such as computers and hubs) can receive
frames properly, clear the TX Tagging check box to set the Switch to remove VLAN tags before sending.
5 Click Add to save the settings to the run-time memory. Settings in the run-time
memory are lost when the Switch’s power is turned off.
5.1.2 Setting Port VID
Use PVID to add a tag to incoming untagged frames received on that port so that the frames are forwarded to the VLAN group that the tag defines.

6.4 How to Use Error Disable and Recovery on the Switch

This tutorial shows you how to shut down a port when:
• there is a loop occurred
or
• too many ARP requests (over 100 packets per second) received on a port
You also want the Switch to wait for a period (10 minutes) before resuming the port automatically, after the problem(s) are gone. Loop guard and Errdiable features are helpful for this demand.
Note: Refer to Section 27.2 on page 297 and Section 31.3 on page 312 for more
information about Loop Guard and Errdiable.
To configure the settings:
1 First, click Advanced Application > Loop Guard. Select the Active option in
the first section to enable loop guard on the Switch. Then select the Active option of the first entry (port *) to enable loop guard for all ports. Click Apply.

6.5 How to Set Up a Guest VLAN

All ports on the Switch are in VLAN 1 by default. Say you enable IEEE 802.1x authentication on ports 1 to 8. Clients that connect to these ports should provide the correct user name and password in order to access the ports. You want to assign clients that connect to ports 1, 2 or 3 to a guest VLAN (200 for example) before they can authenticate with the authentication server. In this guest VLAN, clients can surf the Internet through the default gateway attached to port 10, but are not allowed to access other network resources, such as the mail server or local data base.
