CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
Your Switch is a stand-alone, layer-3, Gigabit Ethernet (GbE) switch with support
for an optional 2-port 10 Gigabit uplink module. The XGS-4528F or XGS-4728F
also provides two 12 Gigabit stacking ports. By integrating router functions, the
Switch performs wire-speed layer-3 routing in addition to layer-2 switching.
The XGS-4526 comes with 20 100/1000 Mbps Ethernet ports and 4 GbE dual
personality interfaces. The XGS-4528F or XGS-4728F comes with 24 GbE dual
personality interfaces. A dual personality interface includes one Gigabit port and
one slot for a mini-GBIC transceiver (SFP module) with one port active at a time.
The XGS-4526 requires 100 VAC to 240 VAC, 0.8 A power.
There are two XGS-4528F or XGS-4728F models. The XGS-4528F or XGS-4728F
DC model requires DC power supply input of -36 VDC to -72 VDC, 1.5 A Max no
tolerance. The XGS-4528F or XGS-4728F AC model requires 100 VAC to 240 VAC,
0.8 A power.
With its built-in web configurat or, 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.
See Chapter 56 on page 463 for a full list of software features available on the
Switch.
1.1.1 Bridging Example
In this example 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 the optional 10 Gigabit uplink module on the
Switch.

1.1.2 High Performance Switching Example
The Switch is ideal for connecting two geographically dispersed networks that
need high bandwidth. In the following example, a company uses the optional 10
Gigabit uplink modules to connect the headquarters to a branch office network.
Within the headquarters network, a company can use trunking to group several
physical ports into one logical hig h er-capacity link. Trunking can be used if for
example, it is cheaper to use multiple lower-speed links than to under-utilize a
high-speed, but more costly, single-port link.

XGS-4526/4528F/4728F User’s Guide
1.1.3 Gigabit Ethernet to the Desktop
The Switch is an ideal solution for small networks which demand high bandwidth
for a group of heavy traffic users. Y ou can conn ect computers an d servers directly
to the Switch’s port or connect other switches to the Switch. Use the optional 10
Gigabit uplink module to provide high speed access to a data server and the
Internet. The uplink module supports a fiber-optic connection which alleviates the
distance limitations of copper cabling.
In this example, all computers can share high-speed applications on the server
and access the Internet. To expand the network, simply add more networking
devices such as switches, routers, computers, print servers and so on.

Chapter 1 Getting to Know Your Switch
1.1.4 IEEE 802.1Q VLAN Application Example
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 or more
groups. 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
increasing network performance by reducing broadcast traffic. VLAN groups can
be modified at any time by adding, moving or changing ports without any recabling.
XGS-4526/4528F/4728F User’s Guide
29
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
1.1.5 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 d evices 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.

1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
30
XGS-4526/4528F/4728F User’s Guide
Chapter 1 Getting to Know Your Switch
• Web Co nfigurator. This is recommended for ev eryday management of the S witch
using a (supported) web browser. See Chapter 4 on page 47.
• Command Line Interface. Line commands offer an alternative to the Web
Configurator and may be necessary to configure advanced features. See the CLI
Reference Guide.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/
restore. See Section 45.8 on page 393.
• SNMP. The device can be monitored and/or managed by an SNMP manager. See
Section 46.3 on page 398.
1.3 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.
• 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 y our password, you will hav e 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.

This chapter shows you how to install and connect the Switch.
2.1 Freestanding Installation
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.
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.

Chapter 2 Hardware Installation and Connection
Note: Do NOT block the ventilation holes. Leave space between devices when
stacking.
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 Mounting the Switch on a Rack
This section lists the rack mounting requirements and precautions and describes
the installation steps.
2.2.1 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.
2.2.1.1 Precautions
• Make sure the rack will safely sup port the combined weight of all the equipment
it contains.
• Make sure the position of the Switch does not make the rack unstable or topheavy. Tak e all necessary precautions to anchor the rack securely before
installing the unit.
2.2.2 Attaching the Mounting Brackets to the Switch

Connect these ports to a computer, a hub, an Ethernet switch or router.
Each interface has one 1000Base-T copper RJ-45 port and one mini-GBIC
(Gigabit Interface Converter) fiber port, with one port active at a time.
• 4 or 24 1000Base-T Ports:
Connect these ports to high-bandwidth backbone network Ethernet
switches using Category 5/5e/6 1000Base-T Ethernet cables.
Use an 8-wire Ethernet cable for Gigabit connections. Using a 4-wire
Ethernet cable limits your connection to 100 Mbps. Note that the
connection speed also depends on what the Ethernet device at the
other end can support.
•4 or 24 Mini-GBIC Ports:
Use Small Form-Factor Pluggable (SFP) transceivers in these ports for
1000Base-X fiber-optic connections to backbone Ethernet switches.
3.1.1 Dual Personality Interfaces
There are 4 or 24 Dual Personality interfaces, comprising 4 or 24 1000Base-T/
mini-GBIC combo ports. For each interface you can connect either to the
1000Base-T port or the mini-GBIC port. The mini-GBIC ports have priority over
the 1000Base-T ports. This means that if a mini-GBIC port and the corresponding
1000Base-T port are connected at the same time, the 1000Base-T port will be
disabled.
3.1.2 1000Base-T Ports
The Switch has 24 1000Base-T auto-negotiating, auto-crossover Ethernet ports.
In 100/1000 Mbps Gigabit Ethernet, the speed can be 100 Mbps or 1000 Mbps.
The duplex mode can be both half or full duplex at 100 Mbps and full duplex only
at 1000 Mbps.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed
(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.

3.1.2.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
3.1.3 Mini-GBIC Slots
These are 4 or 24 slots for Small Form-Factor Pluggable (SFP) transceivers. A
transceiver is a single unit that houses a transmitter and a receiver. Use a
transceiver to connect a fiber-optic cable to the Switch. The Switch does not come
with transceivers. You must use transceivers that comply with the Small FormFactor 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
connectors.
Chapter 3 Hardware Overview
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
To avoid possible eye injury, do not look into an operating fiberoptic module’s connectors.
3.1.3.1 Transceiver Installation
Use the following steps to install a mini GBIC transceiver (SFP or XFP module).
1 Insert the transceiver into the slot with the exposed section of PCB board facing

Note: This is only for the AC model of the Switch.
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.
3.2.5.2 DC Power Connection
Note: This is only for the DC model of the Switch.
The Switch uses a single ETB series terminal block plug with four pins which al lows
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.

3.2.6 External Backup Power Supply Connector
The Switch supports external backup power supply (BPS).
The Switch constantly monitors the sta tus of the internal power supply. The
backup power supply automatically provides power to the S witch in the event of a
power failure. Once the Switch receives power from the backup power supply, it
will not automatically switch back to using the internal power supply even when
the power is resumed.
3.2.7 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 RS-232 console cable to the console port of the
Switch. Connect the female end to a serial port (COM1, COM2 or other COM port)

CHAPTER 5
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 example network:
• Configure an IP interface
• Configure DHCP server settings
• Create a VLAN
• Set port VLAN ID
•Enable RIP
5.1.1 Configuring an IP Interface
On a layer-3 switch, an IP interface (also known as an IP routing domain) is not
bound to a physical port. The default IP address of the S witch is 192.168. 1.1 wi th
a subnet mask of 255.255.255.0.
In the example network, since the RD network is already in the same IP interface
as the Switch, you don’t need to create an IP interface for it. However , if you want
to have the Sales network on a different routing domain, you need to create a
XGS-4526/4528F/4728F User’s Guide

Chapter 5 Initial Setup Example
new IP interface. This allows the Switch to route traffic between the RD and Sales
networks.
Figure 24 Initial Setup Network Example: IP Interface
1 Connect your computer to the MGMT port that is used only for management.
Make sure your computer is in the same subnet as the MGMT port.
2 Open your web browser and enter 192.168.0.1 (the default MGMT port IP
address) in the address bar to access the web configurator. See Section 4.2 on
page 47 for more information.

For the Sales network, enter 192.168.2.1 as the IP address and 255.255.255.0 as
the subnet mask.
XGS-4526/4528F/4728F User’s Guide
5 In the VID field, enter the ID of the VLAN group to which you want this IP
interface to belong. This is the same as the VLAN ID you configure in the Static
VLAN screen.
6 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 Configuring DHCP Server Settings
You can set the Switch to assign network information (such as the IP address,
DNS server, etc.) to DHCP clients on the network.
For the example network, configure two DHCP client pools on the Switch for the
DHCP clients in the RD and Sales networks.

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.

The Switch checks the routing table and then forwards traffic through the default
gateway (R1) based on the destination address. This example shows you how to
configure policy route to send traffic that matches a layer-3 classifier to a different
gateway (R2) for special treatment. The layer-3 classifier groups packets mark ed
with DSCP value 58 into a flow. Packets marked with different DSCP values, such
as 13 are forwarded to the default gateway. The Switch applies policy-based
routing rules to incoming packets prior to the normal routing.

LABEL DESCRIPTION
Status If STP (Spanning Tree Protocol) is enabled, this field displays the STP
state of the port (see Section 13.1.3 on page 149 for more information).
If STP is disabled, this field displays FORWARDING if the link is up,
otherwise, it displays STOP.
LACP This field shows if LACP is enabled on this port or not.
TxPkts This field shows the number of transmitted frames on this port
RxPkts This field shows the number of received frames on this port
Errors This field shows the number of received errors on this port.
Tx KB/s This field shows the transmission speed of data sent on this port in
kilobytes per second.
Rx KB/s This field shows the transmission speed of data received on this port in
kilobytes per second.
Up Time This field shows the total amount of time the connection has been up.
Tx Packet
The following fields display detailed information about packets transmitted.
Unicast This field shows the number of good unicast packets transmitted.
Multicast This fie ld shows the number of good multicast packets transmitted.
Broadcast This field shows the number of good broadcast packets transmitted.
Pause This field shows the number of 802.3x Pause packets transmitted.
Tagged This field shows the number of packets with VLAN tags transmitted.
Rx Packet
The following fields display detailed information about packets received.
Unicast This field shows the number of good unicast packets received.
Multicast This fie ld shows the number of good multicast packets received.
Broadcast This field shows the number of good broadcast packets received.
Pause This field shows the number of 802.3x Pause packets received.
Control This field shows the number of control packets received (including those
with CRC error) but it does not include the 802.3x Pause packets.
TX Collision
The following fields display information on collisions while transmitting.
Single This is a count of successfully transmitted packets for which transmission
is inhibited by exactly one collision.
Multiple This is a count of successfully transmitted packets for which transmission
was inhibited by more than one collision.
Excessive This is a count of packets for which transmission failed due to excessive
collisions. Excessive collision is defined as the number of maximum
collisions before the retransmission count is reset.
Late This is the number of times a late collision is detected, that is, after 512
bits of the packets have already been transmitted.
Error Packet The following fields display detailed information about packets received
that were in error.
