10/100 Mbps RJ-45 Ports
The switches have the following 10/100 Mbps RJ-45 ports:
These ports are auto-sensing, auto-MDIX 10/100 Mbps ports. When you insert a cable into an RJ-45
port, the switch:
Determines whether the cable is a straight-through or crossover cable.
Automatically ascertains the maximum speed (10 or 100 Mbps) and duplex mode (half- or
full-duplex) of the attached device.
After determining this information, the switch configures the RJ-45 port automatically to enable
communications with the attached device, without requiring user intervention.
Gigabit Ethernet Ports
EX17082, EX17162, and EX17242 switches have four Gigabit Ethernet interfaces in the form of two
RJ-45 ports and two fibre optic Small Form Factor Pluggable (SFP) ports. These ports provide a
full-duplex 1000 Mbps (1 Gbps) connection, and can be used to connect upstream to other switches or
to other devices. For example, you can connect a Network Video Recorder (NVR) to one port, and use
the other port to upstream to another switch or the network backbone.
Table 2-1 shows the port designations for the Gigabit Ethernet interfaces. Only one pair of Gigabit
Ethernet ports can be used at a time. If you use one or two RJ-45 Gigabit Ethernet ports, for example,
you cannot use the SFP ports.
Table 2-1. Gigabit Ethernet Port Designations

EX17082, EX17162, and EX17242 Web-Smart Switches User Guide
Note: These ports have also been referred to as mini-GigaBit or (GBIC) ports, but this term has
been made obsolete by SFP.
Note: You can also reboot the switch using the Reboot Device page in the switch’s Web
management interface (see “Reboot Device Page” on page 46).

Checking the Installation
Before you apply power:
Inspect the equipment thoroughly.
Verify that all cables are installed correctly.
Check cable routing to make sure cables are not damaged or create a safety hazard.
Be sure all equipment is mounted properly and securely.
Applying AC Power
EX17082, EX17162, and EX17242 switches have an ON/OFF switch that controls power to the switch.
Before you connect the power cord, select an AC outlet that is not controlled by a wall switch, which
can turn off power to the switch. After you select an appropriate outlet, use the following procedure to
apply AC power.
1. Connect the female end of the supplied AC power adapter cable to the power receptacle on the back
of the switch.
2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.
3. On the rear panel, move the ON/OFF switch to the ON position ( ).
When you apply power:
All green PoE, Link/ACT, and 100M LEDs blink momentarily.
The fans start.
The yellow Power LED goes ON.
The Link/ACT and 100M LEDs for every port connected to a device flash, as the switch conducts a
brief Power On Self-Test (POST).
After the switch passes the POST, the Link/ACT and 100M LEDs for every port connected to a device
go ON. The PoE LEDs also go ON if Power Devices are connected. The switch is now functional and
ready to pass data.
If you do not hear the fans, or if the Power LED is not ON, check that the power cable is plugged in
correctly, the ON/OFF switch is set to the ON position, and that the power source is good and not
controlled by a wall switch. If this does not resolve the problem, see Chapter 5, Troubleshooting.

Topics:
After you install the switch, configure it using the switch’s built-in
Web management interface and a Web browser on a PC.
For the Web browser to access the switch’s Web management
interface, the PC and switch must be on the same subnet. This
means the first time you configure the switch, you must change
your PC’s TCP/IP settings to match the switch’s default subnet of
192.168.2.1.
The procedure for changing your PC’s TCP/IP settings depends
on the PC’s operating system. This chapter describes how to
configure TCP/IP settings for PCs that have a Microsoft Windows
7 operating system.
If your PC is running an operating system other than Windows 7,
refer to the documentation for your operating system to find out
how to change the PC’s TCP/IP settings.

Description
Tx/Rx Ability
Enables or disables a port’s ability to send and receive data on the network. Choices are:
Enable = port can send and receive data.
Disable = port cannot send and receive data.
Auto-Negotiation
Enables or disables a port’s ability to negotiate the communication speed and duplex mode
automatically. Choices are:
Enable = port can auto-negotiate speed and duplex mode.
Disable = port cannot auto-negotiate speed and duplex mode.
Speed
Specifies the maximum speed for a port. Choices are:
1G = maximum port speed is 1 Gbps.
100M = maximum port speed is 100 Mbps.
10M = maximum port speed is 10 Mbps.
Duplex
Specifies the port’s duplex mode. Choices are:
Full = full-duplex.
Half = half-duplex.
Pause
Determines whether the port sends pause frames. When a port gets overloaded, enabling this
setting allows a port to send pause requests to the devices sending it data to allow the
overloaded condition to clear. Choices are:
Enable = send pause frames.
Disable = do not send pause frames.
Backpressure
Enables or disables backpressure on ports operating at 10 or 100 Mbps in half-duplex. During
periods of packet congestion, ports use backpressure to stop their network counterparts from
transmitting more packets temporarily. This prevents a buffer overrun, and the subsequent
loss and retransmission of network packets. You cannot set backpressure on ports where
auto-negotiation is enabled. You can enable backpressure only on ports where the speed and
duplex mode are configured manually. Choices are:
Enable = enable backpressure.
Disable = disable backpressure.

Port Mirroring Page
Path: Port Management > Port Mirroring
The Port Mirroring page lets the switch send network traffic on a port copied to another port
for analysis by a network analyzer. A mirroring session consists of a destination port and at
least one source port. A mirror copy of the traffic on the source port(s) being probed is
transmitted from the source port to the destination probe port. A network analyzer can be
connected to a destination probe port to analyze network traffic.
A port configured as a destination probe port acts as a mirroring port as long as the session is
operationally active. When the session is not active, the port transmits and receives traffic
based on the other configuration parameters.
To configure port mirroring:
1. Next to Dest Port, check the ports you want to designate as destination ports.
2. Using the Monitored Packets drop-down list, click the packets that are to be mirrored.
Choices are:
– Disable = disables mirroring.

Broadcast Storm Control Page
Path: Port Management > Broadcast Storm Control
The Broadcast Storm Control page prevents traffic on a LAN from being disrupted by a
broadcast, multicast, or unicast storm on a port. A LAN storm occurs when packets flood the
LAN, creating excessive traffic and degrading network performance. Errors in the
protocol-stack implementation, mistakes in network configuration, or users issuing a
denial-of-service attack can cause a storm.
Storm control uses rising and falling thresholds to block and restore the forwarding of
broadcast, unicast, or multicast packets. Storm control is configured for the switch as a
whole, but operates on a per-port basis.
To configure broadcast storm control:
1. In the Threshold field, enter a number from 1 to 63 that corresponds to the number of
broadcast packets allowed to enter each port. A higher threshold allows more packets to
pass through.
2. Next to Enable Port, check each port to which you want to apply broadcast storm control.

VLAN Setting Menu
A Local Area Network (LAN) can be defined as a broadcast domain. Hubs, bridges or
switches in the same physical segment or segments connect all end node devices. End
nodes can communicate with each other without the need for a router. Routers connect LANs
together, routing the traffic to appropriate port.
A virtual LAN (VLAN) is a local-area network with a definition that maps workstations on
some other basis than geographic location (for example, by department, type of user, or
primary application). To communicate between VLANs, traffic must go through a router, just
as if they were on two separate LANs.
A VLAN is a group of PCs, servers and other network resources that behave as if they were
connected to a single, network segment — even though they may not be. For example, all
marketing personnel may be spread throughout a building. Yet if they are all assigned to a
single VLAN, they can share resources and bandwidth as if they were connected to the same
segment. The resources of other departments can be invisible to the marketing VLAN
members, accessible to all, or accessible only to specified individuals, depending on how the
IT manager has set up the VLANs.
The Advantages of VLANs
Provides network segmentation. Users who communicate most frequently with each
other can be grouped into common VLANs, regardless of physical location. Each group's
traffic is largely contained within the VLAN, reducing extraneous traffic and improving the
efficiency of the whole network.
Improves management. The addition of nodes, as well as moves and other changes,
can be dealt with quickly and conveniently from a management interface rather than the
wiring closet.
Increases bandwidth and performance. VLANs free up bandwidth by limiting
node-to-node and broadcast traffic throughout the network.
Enhances network security. VLANs create virtual boundaries that can be crossed only
through a router. So standard, router-based security measures can be used to restrict
access to each VLAN.
VLAN Behavior in the Switch
Packets received by the switch will be treated in the following way:
If an untagged packet enters a port configured for tag-based VLAN, the port settings
defined on the VLAN Setting > VLAN Mode page determine whether the packet is
tagged automatically. Each port has a default VLAN ID setting that is user-configurable.
The VLAN ID for each port can be changed on the VLAN Mode page.
57
EX17082, EX17162, and EX17242 Web-Smart Switches User Guide
VLAN mode toggles between tagged- and port-based
VLAN modes. See page 59.
VLAN Member allows ports to join a VLAN. See page 63.
Multi to 1 Setting configures one or more physical
switch ports to a single destination port. See page 66.
If a tagged packet enters a port configured for tag-based VLAN, the port settings defined
on the VLAN Setting > VLAN Mode page determine whether the is tag is ignored or
removed automatically.
If the port in which the packet entered the switch does not have membership with the
VLAN specified by the VLAN ID tag, the packet is dropped. Port VLAN membership
settings are changed on the VLAN Setting > VLAN Member page.
If the port has membership to the VLAN specified by the packet’s VLAN ID, the packet will
be able to be sent to other ports with the same VLAN ID membership.
Packets leaving the switch will be either tagged or untagged, depending on the setting for
that port’s VLAN membership properties.
The switch’s VLAN features can be accessed from the VLAN Setting menu. This menu lets
you perform the following tasks:

VLAN Mode Page
Path: VLAN Setting > VLAN Mode
The VLAN Mode page lets you toggle between two virtual VLAN modes:
Port-based VLAN
Tagged-based VLAN
Port-based VLANs
A port-based VLAN is a group of ports that form a logical Ethernet segment. Each port of a
port-based VLAN can belong to only one VLAN at a time. A port-based VLAN can have as
many or as few ports as needed. The VLAN can consist of all the ports on an Ethernet switch,
or just a few ports. In addition, a port-based VLAN can span switches and consist of ports
from multiple Ethernet switches.
Ports in a port-based VLAN are referred to as untagged ports and the frames received on the
ports as untagged frames. The names derive from the fact that the frames received on a port
do not contain any information that indicates VLAN membership, and that VLAN membership
is determined solely by a port’s PVID.
Tagged-based VLANs
VLAN membership in a tagged-based VLAN is determined by information within the frames
that are received on a port. This differs from a port-based VLAN, where the PVIDs assigned
to the ports determine VLAN membership.
The VLAN information within an Ethernet frame is referred to as a tag or tagged header. A
tag, which follows the source and destination addresses in a frame, contains the VID of the
VLAN to which the frame belongs (IEEE 802.3ac standard). This number uniquely identifies
each VLAN in a network.
59
EX17082, EX17162, and EX17242 Web-Smart Switches User Guide
When the switch receives a frame with a VLAN tag, referred to as a tagged frame, the switch
forwards the frame only to those ports that share the same VID.
A port that receives or transmits tagged frames is referred to as a tagged port. Any network
device connected to a tagged port must be IEEE 802.1Q-compliant. This is the standard that
outlines the requirements and standards for tagging. The device must be able to process the
tagged information on received frames and add tagged information to transmitted frames.
Changing to a Port-Based VLAN
If a VLAN Mode page similar to the following appears, the switch is configured for
tagged-based VLAN.
To switch to a port-based VLAN:

VLAN Member Page
Path: VLAN Setting > VLAN Member
You configure a port to belong to a VLAN by assigning a membership mode that determines
the kind of traffic the port carries and the number of VLANs to which it can belong. The
procedure you use depends on whether you configured the switch for port-based VLAN or
tagged-based VLAN (see “VLAN Mode Page” on page 59).
Port-Based VLANs

Priority Mode Page
Path: QoS Setting > Priority Mode
Quality of Service (QoS) provides the switch with a mechanism to queue and service
high-priority traffic before low- priority traffic. Using the Priority Mode page, you can select the
priority mode the switch uses to queue high- and low-priority traffic.
1. Next to Mode, click one of the following priority modes:
– First-In-First-Out = the switch processes and forwards packets in the order they
arrive.
– All-High-before-Low = the switch services high-priority traffic in its transmit queue
before low-priority traffic.
– Weight-Round-Robin = the switch processes packets in order, but uses a ratio of
high- vs. low-priority packets based on the Low weight and High weight values you
select. These values are converted into percentages for handling low-priority and
high-priority traffic. For example, if Low weight = 3 and High weight = 5, the ratio of
low-priority transmit packets to high- priority transmit packets handled by the switch is
3 to 5.
2. Click Update.

Port 802.1p , IP DS Based Page
Path: QoS Setting > Port 802.1p , IP DS Based
The Class of Service Configuration page lets you use the switch’s Class of Service (CoS)
feature to set up consistent traffic prioritization policies.
CoS prioritizes traffic to prevent less important traffic from consuming network bandwidth,
and slowing down or stopping the delivery of more important traffic. For example, without
CoS, most traffic received by the switch is forwarded with the same priority it had when it
entered the switch. In many cases, such traffic is ‘‘normal’’ priority and competes for
bandwidth with all other normal-priority traffic, regardless of its relative importance to your
organization’s mission. CoS keeps the most important network traffic moving at an
acceptable speed, regardless of current bandwidth usage. This means you can manage
available bandwidth so that the switch transmits the most important traffic first.
1. For each port, check one or more characteristics that indicate to the switch to give packets
with those characteristics higher priority than packets that do not have those
characteristics. For example, to give packets that have VLAN tags and arrive on port 2 a
higher priority than packets on other ports that do not have VLAN tags, check VLAN Tag
for Port No. 2.
2. Click Update.

TCP/UDP Port Based Page
Path: QoS Setting > TCP/UDP Based
Clicking QoS Setting > TCP/UDP Based displays another Class of Service Configuration
page, where you configure CoS settings based on the protocol associated with packets. Each
protocol has an Option drop-down list from which you can specify how the switch handles
frames associated with the protocols.
The Option drop-down list provides the following selections:
F-I-F-O = incoming packets are forwarded using a first-in-first-out scheme.
Discard = incoming packets are discarded at the source port.
Low = incoming packets are forwarded with low priority.
High = incoming packets are forwarded with high priority.
The last row on the page lets you specify CoS settings for a user-defined port.
1. In the Port field, enter a port number.
2. In the Mask field, enter a bit number of the 7-bit IP address that you want the switch to
ignore.
72
EX17082, EX17162, and EX17242 Web-Smart Switches User Guide
Examples:
If UDP/TCP port = 65535 and Mask = 5, the switch takes into account 65530, 65531,
65534, and 65535.
If UDP/TCP port = 65535 and Mask = 0, the switch takes into account 65535 only.
Below this row is a TCP/UDP port QoS function drop-down list that provides two settings:
Override = switch ignores the port-based, IP type of service (ToS)-based, and CoS
settings defined in the Web management interface.
Not Override = switch obeys the port-based, IP ToS-based, and CoS settings defined in
the Web management interface.

LACP = increases the bandwidth between two network devices by distributing the traffic load over multiple
physical links. See the note following this table.
Operation Key
Identifies the group of ports that are eligible to be aggregated into a trunk group. The software assigns a key to each
group of ports automatically. The Web management interface assigns the keys in ascending numerical order,
beginning with 0. You can change a port group’s key to a value from 0 – 65535.
Time Out
Indicates the timeout value of the port. Choices are:
Long = the trunk group has already been formed and the port is therefore using a longer message timeout for the
LACPDU messages exchanged with the remote port. Typically, these messages are used as confirmation of the
health of the aggregate link.
Short = the port has just started the LACPDU message exchange process with the port at the other end of the
link. The S timeout value also can mean that the link aggregation information received from the remote port has
expired and the ports are starting a new information exchange.
Activity
Switch interfaces exchange LACP packets only with partner interfaces that have an active or passive mode
configuration.
Passive = interface responds to LACP packets that it receives, but does not start LACP packet negotiation. This
setting minimizes the transmission of LACP packets.
Active = places an interface into an active negotiation state, in which the interface starts negotiations with other
interfaces by sending LACP packets.
Submit Button

The Output Queuing Aging Time section is used to avoid poor utilization of the switch.
When a packet is stored in the switch for a long time, the time slot defined by the protocol will
expire and this packet becomes useless. To prevent these useless packets from wasting the
bandwidth, the switch provides an option to enable the queue aging function. Once enabled,
the switch monitors the aging timer for each packet before it is sent out. A packet that stays in
a queue for a long time will be discarded.

VLAN Striding
By selecting this function, the switch forwards unicast packets to the destination port,
regardless of whether the destination port is in the same VLAN.
IGMP Snooping
When this function is enabled, the switch executes IGMP snooping version 1 and version 2
without the intervention of the CPU. The switch handles Internet Group Management
Protocol (IGMP) report packets automatically. If you enable Leave packet will be forwarded
to IGMP router ports and members want to leave this multicast group, the IGMP leave
packet will be forwarded to the router ports.
VLAN Uplink Setting
This section lets you define the “Uplink port.” This port normally is the port attached to the
uplink router. If you set this function, any frame transferred to other VLAN members is
forwarded out the uplink port only.
For example:
1. Set ports 1, 2, and 3 to the same VLAN and set ports 4, 5 and 6 to the same VLAN.
2. Set port 01 to Uplink1, set port 4 to Uplink2, and then click Update.

Additional Troubleshooting Suggestions
If the suggestions in Table 5-1 do not resolve your problem, refer to the troubleshooting
suggestions in this section.
Network Adapter Cards
Be sure the network adapter cards installed in the PC used to configure the switch are in
working condition and the latest software driver has been installed.
Configuration
If problems occur after altering the switch’s network configuration, restore the original
connections and determine the problem by implementing the new changes one step at a
time. Be sure cable distances, repeater limits, and other physical aspects of the installation
do not exceed the Ethernet limitations.
Switch Integrity
If required, verify the integrity of the switch by resetting it. To reset the switch, use the reset
button on the front panel (see “Reset Button” on page 18) or use the Administrator >
Reboot Device page on the switch’s Web management interface (see “Reboot Device Page”
on page 46). If the problem continues, contact EtherWAN Systems technical support.
Auto-Negotiation
The 10/100 Mbps ports negotiate the correct duplex mode and speed if the switch is
configured for auto-negotiation (this is the switch’s default setting) and the device at the other
end of the link supports auto-negotiation. If the device does not support auto-negotiation, the
switch determines only the speed correctly and the duplex mode defaults to half-duplex.
The Gigabit ports on the switch negotiate speed, duplex mode, and flow control, provided the
attached device supports auto-negotiation.
