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.

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.

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.
