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

1-1

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

VLAN Settings

This page allows you to create an d delete VLANs (Virtual LANs) and to change the
VLAN membership an d behaviour of individual ports. VLA N s ar e powerful, but can
be difficult to set up properly. Each row of the table corresponds to one port or trunk;
trunked ports cannot be con figured individually.

Introduction to VLANs

VLANs are logical partitions of the physical LAN. You can use VLANs to increase
network performanc e or impr ove internal network sec ur ity.

3-23

Configuring the Switch

If the network has adequa te per f or m ance and security for your c ur ren t needs, it is
recommended that yo u leave the VLAN settings in the def ault configuration. The
default configuration is as follows:

• All ports are members of VLAN 1

• The switch management in terf a ce i s on V LAN 1 (this cannot be changed)

• All ports have a Port VLAN ID (PVID) of 1

• All ports can send and receive both VLAN-tagged and untagged packets (that is,
they are hybrid ports)

In the default configuration, any port is able to send traffic to any other port and a PC
connected to any port will be able to access the management interface. Broad cast
traffic, for example, will be floode d t o al l p or ts on the sw it ch.

There are three different parameters that can be configured for each port on the
switch; VLAN ID (VLAN membership), PVID and Packet Type. Note that the ports
within a trunk cannot be con figured individually; con figure the trunk instead ( trunks
are labelled T1 to T4).

Field Attributes

• Port/Trunk – The port-number of t he port or the ID of a trunk. This cannot be
changed.

• VLAN Awareness – VLAN aware ports will strip the VLAN tag from received
frames and insert the tag in tran sm i t te d fram es (except PVID). VLAN unaw ar e
ports will not strip the tag from received frames or insert the tag in transmitted
frames.
For QinQ operation, a cus tom er port should be set to VLAN unaware and a
provider port (trunk port) sh ould be set to VLAN aware.

• Packet Type – Sets the interface to accept all frame t ypes, including tagged or
untagged frames, or only tagged frames. When set to receive all frame types, any
received frames that are untagged are assigned to the default VLAN. PCs should
be connected to ports with Packet Type set to “All.” PCs cannot, in general, send
or receive tagged packe ts . Switches should be conn ect ed to each other with
Packet Type set to “Tagged.” If the Packet Type is set to “All,” the port can accept
incoming tagged and untagged packets. Untagged packets will be associated with
the VLAN identified by the PVID. Tagged packets will be dropped unless the port
is a member of the VLAN identified by the VLAN tag in the packet. Outgoing
packets will be tagged unless the packet’s VLAN ID is the sam e as the PVID. If
the Packet Type is set to “Tag ged,” the port will drop untagg ed packets and will
only send and receive tagged packets. Tagged packets will be dropped unl ess the
port is a member of the VLAN identified by the VLAN tag in the packet. The PVID
has no effect in this case.(Optio n: All, Tagged; Default: All)

• PVID –

VLAN ID assigned to untagged frames received on the interface. The PVID
(Port VLAN ID) is the VLAN ID that is associated with untagged, ingress packets.
It is not possible to remove a port from VLAN 1 unless its PVID has been changed
to something other than 1. The PVID has no effect on ports that have Packet Type
set to Tagged. (Default: 1)

802.1X

Network switches can provide open and easy access to ne t w ork resources by
simply attaching a client PC. Alt hough this automatic conf i gur at i on a nd access is a
desirable feature, it also allo w s unauthorized person nel to easily intrude and
possibly gain access to sensitive network data. With IEEE 802.1X (802.1X), access
to all switch ports in a network c an be centrally controlled from a server, which
means that authorized users can use the same cr edentials for authenticat i on f ro m
any point within the netwo rk .

802.1 X Setting

• RADIUS IP - Sets the RADIUS server IP address.

• RADIUS UDP Port - Sets the UDP port to the use for the external RADIUS server.

• RADIUS Secret - Sets the text string used for encryption between the switch and

interval specified by the Re-authentication Period. Re-authentication can be used
to detect if a new device is p lugged into a switch port.

• Reauthentication Period - Sets the time period after which a connect ed client
must be re-authenticated.

• EAP timeout - The time the switch shall wait for the supplicant response before
re-transmitting a pack et .

Port Setting

• Port - The port number.

• Admin Sta te - Sets the authentication mode to one of the foll owing options:

• Auto - Requires a 802.1X-aware client to be authorized by the authentication
server. Clients that are not 802.1X-aware wi ll be deni ed access.

• Force-Authorized - Forces the port to grant access to all clients, either

802.1X-aware or otherwise.

• Force-Unauthorized - Forces the port to deny access to all clien ts, eithe r

802.1X-aware or otherwise.

• Port State - The state of the port.

• Reset - Two options av ai la ble:

• Re-Authenticate - Schedules a reaut hentication to whenever the qui et - per i od
of the port runs out.

• Force-Reinitialize - Bypasses the quiet-period of the port and enable s
immediate reauthen tic at io n re gar dl ess of the status for the quiet-p er io d.

The reason for a “quiet-period” follows: If a re-authentication fails, the IEEE

Note:

802.1X standard enforces a so-called “quiet-period” in which the authenticator
(switch) shall be quiet and not re-try another authentication – also packets from
supplicant are discarded – this way “brute-f orc e” attacks are prevent ed.

SNMP

Simple Net w ork Management Protocol (SNMP) is a commu nication protocol
designed specifically f or managing devices on a net w or k. Equipment commonly
managed with SNMP in cludes switches, routers and host computers. SNMP is
typically used to configure these devices for proper operation in a network
environment, as well as to monitor them to evaluate performance or detect potential
problems. The switch in cl ud es an onboard SNMP age nt tha t c ont i nuo usly monitors
the status of its hardware, as well as t he traffic passing through its ports. A network
management station can ac cess this information us i ng ne twork management
software. Access rights to the onboard agent are controlled by community strings. To
communicate with the swi tc h, th e m anagement station must firs t su bm it a val i d
community string for au t hentication.

Field Attributes

• SNMP Enabled -Activate or deactivate S N M P.

• SNMP Trap Destination - IP address of the trap manager.
Traps indicating status changes are issued by the sw i tc h t o sp eci f ie d t ra p
managers. You must specify trap managers so that key events are reported by this
switch to your managem ent station. SNMP trap des tination specifies the IP
address of th e t r ap manager.

POE

The switc h can pr ov id e DC pow er to a wi de r ang e of c on nec te d d evi c es, el im in at in g
the need for an additional power source and cutting down on the amount of cabl es
attached to each device. Once configured to supply power, an automatic detection
process is initiali zed by the switch that is authenticated by a PoE si gnature from the
connected device. Detection and authentication prevent damage to non-802.3af
compliant devices.

The switch’s power managem ent enables total switch power and individual port
power to be controlled withi n t he s w itc h pow er budget. Port power can b e
automatically turned on and off for connected devices, an d a per-port power priority
can be set so that the switch never exceeds its power budget. When a device is
connected to a switch port, its power requirements are detected by the switch before
power is supplied. If the pow e r r equired by a device exceed s t he power budget of
the port or the whole switc h, power is not supplied.

Ports can be set to one of four power priority levels, critical, high, medium, or low. To
control the power suppl y wi t hi n t he switch’s budget, ports set at critical or hig h
priority have power enabled in preference to those ports set at low priori ty. For
example, when a device is connected to a port set to cri tical priority, the switch
supplies the required power, if necessary by dropping power to ports set for a lower
priority. If power is dropped to some low-priority po rts and lat er th e power demands
on the switch fall back within i ts bud get , th e dr opped power is automatic all y
restored. If PoE port priority is not configured, power is automatically allocated to the
port according its port number, ie. lower numbered ports are assigned a higher
priority f o r p o w er delivery.
