Chapter 1: Introduction

The EZ Switch 10/100/1000 SM C G S8 P-Smart is a managed Gigabit Po E sw itc h
that delivers performance and control to your network. It provides 8 full-duplex
1000BASE-T ports that significantly improve networ k performance and boost
throughput using featu re s configured through a we b-b ased management inter f ace.
With 16 Gigabits of throughpu t b andwidth, this switch provides an effective solution
to meeting the growing de m ands on your network.

Description of Software Features

The switch provides a wide range of advanced performance enhancing features.
Flow control eliminate s th e loss of packets due to bottlenecks caused by port
saturation. Broadcast storm suppression prevents broadcast traffic storms from
engulfing the network. CoS priority queueing ensures the minimum delay for moving
real-time multimedia da ta acr os s th e network. While multicas t fi lter i ng provides
support for real-time net wor k applications. Some of the m anagement features are
briefly described below.

Configuration Backup and Restore – You can save the current configur at i on
settings to a file on the web m an agement station, and later dow nload this file to
restore the switch con figu ration settings.

Authentication – The sw itch supports port-based user authentication via the IEEE

802.1X protocol. This prot oc ol use s th e Ext ensible Authentication Pr otocol over
LANs (EAPOL) to request user credentials from the 802.1X client, and then verifies
the client’s right to access the net w or k vi a a n aut hentication server.

Port Configuration – You can manually configure the speed, duplex mode, and
flow control used on spe ci fic p or ts, or use aut o- negotiation to detect th e con n e ct io n
settings used by the attache d device. Use the full-du plex mode on ports whenever
possible to double the th ro ughput of switch connect ions. Flow control is enabl ed to
control network traffic durin g periods of congestion and prevent the loss of packets
when port buffer thresholds are exceeded. The switch supports flow control based
on the IEEE 802.3x standard.

Port Mirroring – The switch can unobtr usi vely mirror traffic from any port t o a
monitor port. You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.

Port Trunking – Ports can be combined into an aggregate connection. Trunks can
be manually set up or dynamically configured using IEEE 802.3ad Link Aggregation
Control Protocol (LACP). The add itional ports dramatically increase the th ro ughput
across any connecti on, and provide redundan cy by taking over the load if a port in
the trunk should fail. The switch supports up to 4 trunk s.

Broadcast Storm Control – Broadcast suppression prevents broadcast traffic from
overwhelming the netw or k. W hen enabled on a port, the lev el of broadcast traffic

Introduction

passing through the port is rest r ic ted. If broadcast traffic rises above a pr e- defined
threshold, it will be throttle d unt i l the level fa lls back beneath the thresho ld .

Static Addresses – A static address can be assigned to a sp ecific interface on this
switch. Static addresses are bound to the assigned interface and will not be moved.
When a static address is seen on another interface, the address will be ignored and
will not be written to the add re ss tab le . Static addresses ca n be used to provide
network security b y restricting access for a known host to a spe ci f ic por t.

IEEE 802.1D Bridge – The swit ch s upports IEEE 802.1D transparent br id ging. The
address table facilitates data switch ing by learning addresses , and then filtering or
forwarding traffic based on thi s in fo rmation. The address table su pp orts up to 8K
addresses.

Store-and-Forward Switching – The switch copies each frame in to its memory
before forwarding them to another port. This ensures that all frames are a standard
Ethernet size and have bee n verified for accuracy wit h th e cy cl ic red undancy check
(CRC). This prevents bad fram es from entering the netwo rk and w asting bandwidth.

To avoid dropping frames on congested ports, the switch provides 400 KB for frame
buffering. This buffer can queue packets awaiting transmission on congested
networks.

Virtual LANs – The switch supports up to 64 VLANs. A Virtual LAN is a collection of
network nodes that share the same collision domain regardless of their physical
location or connection poi nt in the net w ork. The switch supports tagged VLANs
based on the IEEE 802.1Q standard. Ports can be manually ass igne d to a spe cific
set of VLANs. This allows the switch to restrict traffic to the VLAN groups to which a
user has been assigned. By segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade performance in a flat network.

• Simplify network mana gement for node change s/ m oves by remotely configuring
VLAN membership for a ny port, rather than having to m anually change the
network connection.

• Provide data security by restricting all traffic to the originating VLAN.

Power-over-Ethernet (PoE) – The switch’s eight RJ-45 ports support the IEEE

802.3af PoE standard that enables DC power to be suppli ed to attached devices

over wire pairs in the connecting Et hernet cable. Any 802.3af co m pl ia nt dev i ce
attached to a port can directly dr aw power from the switch over th e Et hernet cable
without requiring its own separate power source. This capability gives network
administrators centralized power control for devices such as IP phones and wireless
access points, which translates into greater netwo rk avail ability.

A maximum PoE power bud get fo r the switch (power available to al l sw i tch por ts) is
defined so that power can be centrally managed, preventing overload co ndit io ns at
the power source. If the power demand from devi ces connected to the sw itc h
exceeds the power budget, the switch uses port power priority settin gs to limit the
supplied power.

Chapter 2: Initial Configuration

To make use of the managemen t feat ur es of your EZ Sw i tch, you must first
configure it with an IP address that is compatible with the network it is being installed
in. This should be done be fo re you permanently install the switc h i n th e network.

Follow this procedure:

1. Place your EZ Switch close to the PC that you intend to use for configuration. It
helps if you can see the front panel of th e sw it ch while working on your PC.

2. Connect the Ethernet po rt of your PC t o any por t o n th e front panel of your EZ
Switch. Connect power to the switch and verify that you have a link by checking
the front-panel LEDs.

3. Check that your PC has an IP address on the same subnet as the switch. The
default IP address of the swi tc h is 192.168.2.10 and the sub net mask is

255.255.255.0, so the PC and swi t ch are on th e sam e subnet if they both have
addresses that start 192.168. 2.x. If the PC and switch are not on the same
subnet, yo u m ust ma nua l ly set t he P C’ s I P ad dr ess to 19 2. 16 8. 2. x ( whe re “x ” i s
any number from 1 to 255, except 10). If you are unfamiliar with this process,
see “Changing a PC’s IP Address” on page 1-37.

4. Open your web browser and enter the address http://192.168.2.10. If your PC is
properly configured, you will see the login page of your EZ Switch. If you do not
see the login page, repeat step 3.

5. Enter the default password “sm cadmin” and click on the Logi n button.

6. From the menu, click on SYSTEM, then click on LAN Settings. On the LAN
Settings page, enter the new IP address, Subnet Mask and G at eway IP
Address fo r t he switch, th en click on the APPLY button.

No other configuration changes are required at this stag e, but it is recommended
that you change the admini strator’s password be fo re log gi ng out. To change the
password, click SYSTEM, Password, and then fill in all the fields on the Password
Settings page before clicking on the APPLY button.

Chapter 3: Configuring the Switch

Using the Web Interface

This switch provides an embedded HTTP web agent. Using a web browser you can
configure the switch and view statistics to monitor net w or k ac t iv ity. The web agent
can be accessed by any com puter on the network using a standard web browser
(Internet Explorer 5.5 or above, or Mozilla Firefox 1.0 or abo ve) .

Prior to accessing the switch from a web browser, be sure you have first performed
the following tasks:

1. Confi gure th e switc h with a valid I P addr ess, su bnet mas k, and de faul t gatew ay .
(Defaults: IP address 192.168.2.10; Subnet mask 255.255.255.0; Gatew ay

0.0.0.0)

2. Set a new password using the we b i nt er fa ce . (D ef aul t: “sm c adm i n”). Access to
the web interface is cont rolled by the password. See “Con figuring the Logon
Password” on page 3-12.

If you cannot remember the switch's IP address, you can restore the original

Note:

settings by following the procedure described in the “Troubleshooting” section.

Navigating the Web Browser Interface

To acce ss the web-browser inte rface you must first enter a passw ord. The user has
read/write access to all configuration parameters and statistics. The default
password for the switch is “smcadmin.”

If user input is not detected within five minutes, the current session is terminated.

Note:

Home Page

When your web browse r co nnects with the switch’s web agent , th e home page is
displayed as shown below. The home page displays the Main Menu on t he l eft side
of the screen and System Info rm ation on the right side. The M ai n M en u links are
used to navigate to other m enus, and display confi gur at ion parameters and
statistics.
