With its built-in web configurator, 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.

1.2 Software Features

This section describes the general software features of the switch.

DHCP Client

MODEL

ES-3124 ES-3124-4F ES-3124PWR ES-3124F

X

DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual
computers to obtain TCP/IP configuration at start-up from a server. You can configure the
switch as a DHCP client to obtain TCP/IP information (such as the IP address and subnet
mask) from a DHCP server. If you disable the DHCP service, you must manually enter the
TCP/IP information.

Chapter 1 Getting to Know Your Switch 33

ES-3124 Series User’s Guide

VLAN

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Devices on a logical network belong to one group. A device can
belong to more than one group. With VLAN, a device cannot directly talk to or hear from
devices that are not in the same group(s); the traffic must first go through a router.

Queuing

Queuing is used to help solve performance degradation when there is network congestion.
Three scheduling services are supported: Strict Priority Queuing (SPQ), Weighted Round
Robin (WRR) and Weighted Fair Schedule (WFS). This allows the switch to maintain separate
queues for packets from each individual source or flow and prevent a source from
monopolizing the bandwidth.

Port Mirroring

Port mirroring allows you to copy traffic going from one or all ports to another or all ports in
order that you can examine the traffic from the mirror port (the port you copy the traffic to)
without interference.

Static Route

Static routes tell the switch how to forward IP traffic when you configure the TCP/IP
parameters manually.

IGMP Snooping

The switch supports IGMP snooping enabling group multicast traffic to be only forwarded to
ports that are members of that group; thus allowing you to significantly reduce multicast
traffic passing through your switch.

Multicast VLAN Registration (MVR)

Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand
(MoD)) using multicast traffic across a network. MVR allows one single multicast VLAN to
be shared among different subscriber VLANs on the network.

This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs
and simplifies multicast group management.

STP (Spanning Tree Protocol) / RSTP (Rapid STP)

(R)STP detects and breaks network loops and provides backup links between switches,
bridges or routers. It allows a switch to interact with other (R)STP -compliant switches in your
network to ensure that only one path exists between any two stations on the network.

The switch allows you to create multiple STP configurations and assign ports to a specific tree.

34 Chapter 1 Getting to Know Your Switch

ES-3124 Series User’s Guide

Link Aggregation

Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity
link. You may want to trunk ports 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.

Port Authentication and Security

For security, the switch allows authentication using IEEE 802.1x with an external RADIUS
server and port security that allows only packets with dynamically learned MAC addresses
and/or configured static MAC addresses to pass through a port on the switch.

VLAN Stacking

Use VLAN stacking to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that
enter the network. By tagging the tagged frames (“double-tagged” frames), the service
provider can manage up to 4,094 VLAN groups with each group containing up to 4,094
customer VLANs. This allows a service provider to provide different service, based on
specific VLANs, for many different customers.

Differentiated Services (DiffServ)

With DiffServ, the switch marks packets so that they receive specific per-hop treatment at
DiffServ-compliant network devices along the route based on the application types and traffic
flow.

Classifier and Policy

You can create a policy to define actions to be performed on a traffic flow grouped by a
classifier according to specific criteria such as the IP address, port number or protocol type,
etc.

Cluster Management

Cluster Management allows you to manage switches through one switch, called the cluster
manager. The switches must be directly connected and be in the same VLAN group so as to be
able to communicate with one another using same cluster management implementation.

Maintenance and Management Features

• Access Control

You can specify the service(s) and computer IP address(es) to control access to the switch
for management.

• Cluster Management

Cluster management (also known as iStacking) allows you to manage switches through
one switch, called the cluster manager. The switches must be directly connected and be in
the same VLAN group so as to be able to communicate with one another.

Chapter 1 Getting to Know Your Switch 35

ES-3124 Series User’s Guide

• Configuration and Firmware Maintenance

You can backup or restore the switch configuration or upgrade the firmware on the
switch.

1.3 Hardware Features

This section describes the hardware features of the switch.

24 10/100 Mbps Fast Ethernet Ports

Connect up to 24 computers or switches to the 10/100 Mbps auto-negotiating, automatic cable
sensing (auto-MDIX) Ethernet RJ-45 ports.

24 100 Mbps Fast Ethernet SFP Slots

In the ES-3124F, you can install compatible 100 Mbps SFP transceivers in these 100Mbps
slots to connect up to 24 computers or switches.

ES-3124 Series User’s Guide

PoE (Power over Ethernet)

The ES-3124PWR can provide power to a device (that supports PoE) such as an access point
or a switch through a 10/100Mbps Ethernet port.

2 Dual-personality Interfaces

The switch has two dual personality interfaces for uplink. A dual personality interface includes
one Gigabit port and one slot for mini-GBIC transceiver (SFP module) with one port active at
a time.

Mini-GBIC Slots

Install SFP transceivers in these slots to connect to other Ethernet switches at longer distances
than the Ethernet port.

Gigabit Ethernet Ports

These ports allow the switch to connect to another WAN switch or daisy-chain to other
switches.

Management Port

Connect a computer to this port for management purposes. You cannot access the network
through this port.

Chapter 1 Getting to Know Your Switch 37

ES-3124 Series User’s Guide

Console Port

Use the console port for local management of the switch.

Backup Power Supply Port

Connect a backup power supply device to this port to ensure uninterrupted network connection
in the event of a power failure.

Fans

The fans cool the switch sufficiently to allow reliable operation of the switch in even poorly
ventilated rooms or basements.

1.4 Applications

This section shows a few examples of using the switch in various network environments.

1.4.1 Backbone Application

In this application, the switch is an ideal solution for small networks where rapid growth can
be expected in the near future.

The switch can be used standalone for a group of heavy traffic users. You can connect
computers directly to the switch’s port or connect other switches to the switch.

In this example, all computers can share high-speed applications on the server. To expand the
network, simply add more networking devices such as switches, routers, computers, print
servers etc.

38 Chapter 1 Getting to Know Your Switch

Figure 1 Backbone Application

1.4.2 Bridging Example

In this example application 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 a
Gigabit Ethernet/mini-GBIC port on the switch.

ES-3124 Series User’s Guide

Moreover, the switch eases supervision and maintenance by allowing network managers to
centralize multiple servers at a single location.

Figure 2 Bridging Application

1.4.3 High Performance Switched Example

The switch is ideal for connecting two networks that need high bandwidth. In the following
example, use trunking to connect these two networks.

Chapter 1 Getting to Know Your Switch 39

ES-3124 Series User’s Guide

Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not
feasible for most people due to the expense of replacing all existing Ethernet cables and
adapter cards, restructuring your network and complex maintenance. The switch can provide
the same bandwidth as ATM at much lower cost while still being able to use existing adapters
and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.

Figure 3 High Performance Switched Application

1.4.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANs.

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 group. A station can
belong to more than one group. 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 8 on page 93.

1.4.4.1 Tag-based VLAN Example

Ports in the same VLAN group share the same frame broadcast domain thus increase network
performance through reduced broadcast traffic. VLAN groups can be modified at any time by
adding, moving or changing ports without any re-cabling.

40 Chapter 1 Getting to Know Your Switch

Figure 4 Tag-based VLAN Application

1.4.4.2 VLAN Shared Server Example

Shared resources such as a server can be used by all ports in the same VLAN as the server, as
shown in the following example. In this example, only ports that need access to the server
need belong to VLAN 1. Ports can belong to other VLAN groups too.

Use mini-GBIC transceivers in these slots for fiber-optic connections to backbone
network Ethernet switches or use them to daisy-chain other switches.

The 24 10/100 Mbps RJ-45 Ethernet ports are compliant with the IEEE 802.3af power
over Ethernet standard.

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 console cable to the console port of the switch. Connect the
female end to a serial port (COM1, COM2 or other COM port) of your computer.

3.1.2 Ethernet Ports

The switch has 24 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/
100Mbps Fast Ethernet, the speed can be 10Mbps or 100Mbps and the duplex mode can be
half duplex or full duplex.

The ES-3124 and ES-3124PWR also come with two pairs of Gigabit Ethernet/mini-GBIC
ports. The mini-GBIC ports have priority over the Gigabit ports. This means that if a mini­GBIC port and the corresponding Gigabit port are connected at the same time, the Gigabit port
will be disabled. The speed of the Gigabit Ethernet ports can be 100Mbps or 1000Mbps and
the duplex mode can be half duplex (at 100 Mbps) or full duplex.

An auto-negotiating port can detect and adjust to the optimum Ethernet speed and duplex
mode (full duplex or half duplex) of the connected device.

Chapter 3 Hardware Overview 49

ES-3124 Series User’s Guide

An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through 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 Transceiver Slots

These are slots for mini-GBIC (Gigabit Interface Converter) transceivers or 100Mbps SFP
(Small Form-Factor Pluggable) transceivers. A transceiver is a single unit that houses a
transmitter and a receiver. The switch does not come with transceivers. You must use
transceivers that comply with the SFP Transceiver MultiSource Agreement (MSA). See the
SFF committee’s INF-8074i specification Rev 1.0 for details.

There are two pairs of Gigabit Ethernet/mini-GBIC ports. The mini-GBIC ports have priority
over the Gigabit ports. This means that if a mini-GBIC port and the corresponding Gigabit port
are connected at the same time, the Gigabit port will be disabled.

The ES-3124-4F and ES-3124F also have two mini-GBIC ports for connection to other
switches.

The ES-3124F has 24 100Mbps SFP ports to connect to a computer or a switch.

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.

• Type: SFP connection interface

• Connection speed: 1 Gigabit per second (Gbps)

Note: To avoid possible eye injury, do not look into an operating fiber-optic module’s

connectors.

3.1.3.1 Transceiver Installation

Use the following steps to install a mini GBIC transceiver or 100Mbps SFP transceivers.

1 Insert the transceiver into the slot with the exposed section of PCB board facing down.

source. Make sure that no objects obstruct the airflow of the fans.

3.2.2 External Backup Power Supply Connector

The switch supports external backup power supply (BPS).

The backup power supply constantly monitors the status of the internal power supply. The
backup power supply automatically provides power to the switch 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.

8 Changing a service port number but forgetting it.

Note: Be careful not to lock yourself and others out of the switch.

Try using the out-of-band management port before resetting the switch. The
default IP address is 192.168.0.1.

4.7 Resetting the Switch

If you lock yourself (and others) out of the switch, you can try using out-of-band management.
If you still cannot correct the situation or forgot the password, you will need to reload the
factory-default configuration file.

4.7.1 Reload the Configuration File

Uploading the factory-default configuration file replaces the current configuration file with the
factory-default configuration file. This means that you will lose all previous configurations
and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no
parity, one stop bit and flow control set to none. The password will also be reset to “1234” and
the IP address to 192.168.1.1.

To upload the configuration file, do the following:

1 Connect to the console port using a computer with terminal emulation software. See

Section 3.1.1 on page 49 for details.

2 Disconnect and reconnect the switch’s power to begin a session. When you reconnect the

switch’s power, you will see the initial screen.

This chapter shows how to set up the switch for an example network.

5.1 Overview

The following lists the configuration steps for the initial setup:

• Create a VLAN

• Set port VLAN ID

• Configure the switch IP management address

ES-3124 Series User’s Guide

CHAPTER 5

Initial Setup Example

5.1.1 Creating a VLAN

VLANs confine broadcast frames to the VLAN group in which the port(s) belongs. You can
do this with port-based VLAN or tagged static VLAN with fixed port members.

In this example, you want to configure port 1 as a member of VLAN 2.

Figure 26 Initial Setup Network Example: VLAN

Chapter 5 Initial Setup Example 65

ES-3124 Series User’s Guide

1 Click Advanced Application and VLAN in the navigation panel and click the Static

VLAN link.

2 In the Static VLAN screen, select

ACTIVE, enter a descriptive name
in the Name field and enter 2 in the
VLAN Group ID field for the
VLAN2 network.

Note: The VLAN Group ID field in

this screen and the VID field in
the IP Setup screen refer to
the same VLAN ID.

3 Since the VLAN2 network is connected to port 1 on the switch, select Fixed to configure

port 1 to be a permanent member of the VLAN only.

4 To ensure that VLAN-unaware devices (such as computers and hubs) can receive frames

properly, clear the TX Tagging check box to set the switch to remove VLAN tags before
sending.

5 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 Setting Port VID

Use PVID to add a tag to incoming untagged frames received on that port so that the frames
are forwarded to the VLAN group that the tag defines.

In the example network, configure 2 as the port VID on port 1 so that any untagged frames
received on that port get sent to VLAN 2.

5.2 Configuring Switch Management IP Address

The default management IP address of the switch is 192.168.1.1. You can configure another IP
address in a different subnet for management purposes. The following figure shows an
example.

Figure 28 Initial Setup Example: Management IP Address

1 Connect your computer to any Ethernet port on the switch. Make sure your computer is

in the same subnet as the switch.

2 Open your web browser and enter 192.168.1.1 (the default IP address) in the address bar

to access the web configurator. See Section 4.2 on page 55 for more information.

For the VLAN2 network, enter

192.168.2.1 as the IP address and

255.255.255.0 as the subnet
mask.

5 In the VID field, enter the ID of

the VLAN group to which you
want this management IP address
to belong. This is the same as the
VLAN ID you configure in the
Static VLAN screen.

6 Select the Manageable check

box to allow the switch to be
managed from the ports
belonging to VLAN2 using this
specified IP address.

Click Add to save your changes back
to the run-time memory. Settings in
the run-time memory are lost when the switch’s power is turned off.

7.4 Introduction to VLANs

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Devices on a logical network belong to one group. A device can
belong to more than one group. With VLAN, a device cannot directly talk to or hear from
devices that are not in the same group(s); the traffic must first go through a router.

In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security
among the subscribers. When properly configured, VLAN prevents one subscriber from
accessing the network resources of another on the same LAN, thus a user will not see the
printers and hard disks of another user in the same building.

VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast
packets go to each and every individual port. With VLAN, all broadcasts are confined to a
specific broadcast domain.

Priority Queue Assignment
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that

contains bits to define class of service. Frames without an explicit priority tag are given the default
priority of the ingress port. Use the next two fields to configure the priority level-to-physical queue
mapping.

The switch has eight physical queues that you can map to the 8 priority levels. On the switch, traffic
assigned to higher index queues gets through faster while traffic in lower index queues is dropped if the
network is congested.

Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d
standard (which incorporates the 802.1p).

Level 7 Typically used for network control traffic such as router configuration messages.

Level 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the

7.6.1 Management IP Addresses

The switch needs an IP address for it to be managed over the network. The factory default IP
address is 192.168.1.1. The subnet mask specifies the network number portion of an IP
address. The factory default subnet mask is 255.255.255.0.

You can configure up to 64 IP addresses which are used to access and manage the switch from
the ports belonging to the pre-defined VLAN(s).

Full-duplex mode operation only applies to point-to-point access (for example, when attaching
the switch to a workstation, server, or another switch). When connecting to hubs, use a
standard cascaded connection set at half-duplex operation.

Auto-negotiation regulates the speed and duplex of each port, based on the capability of both
devices. When auto-negotiation is turned on, an Ethernet port on the ZyXEL switch negotiates
with the peer automatically to determine the connection speed and duplex mode. If the peer
Ethernet port does not support auto-negotiation or turns off this feature, the ZyXEL switch
determines the connection speed by detecting the signal on the cable and using half duplex
mode. When the ZyXEL switch’s auto-negotiation is turned off, an Ethernet port uses the
preconfigured speed and duplex mode when making a connection, thus requiring you to make
sure that the settings of the peer Ethernet port are the same in order to connect.

CHAPTER 8

The type of screen you see here depends on the VLAN Type you selected in the Switch Setup
screen. This chapter shows you how to configure 802.1Q tagged and port-based VLANs.

8.1 Introduction to IEEE 802.1Q Tagged VLAN

A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN
membership of a frame across bridges - they are not confined to the switch on which they were
created. The VLANs can be created statically by hand or dynamically through GVRP. The
VLAN ID associates a frame with a specific VLAN and provides the information that switches
need to process the frame across the network. A tagged frame is four bytes longer than an
untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the
type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts
after the source address field of the Ethernet frame).

VLAN

The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet
switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not
be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID,
giving a possible maximum number of 4,096 (212) VLANs. Note that user priority and VLAN
ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a
priority frame, meaning that only the priority level is significant and the default VID of the
ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to
identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN
configurations are 4,094.

8.1.1 Forwarding Tagged and Untagged Frames

Each port on the switch is capable of passing tagged or untagged frames. To forward a frame
from an 802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the switch first
decides where to forward the frame and then strips off the VLAN tag. To forward a frame
from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the switch first
decides where to forward the frame, and then inserts a VLAN tag reflecting the ingress port's
default VID. The default PVID is VLAN 1 for all ports, but this can be changed.

A broadcast frame (or a multicast frame for a multicast group that is known by the system) is
duplicated only on ports that are members of the VID (except the ingress port itself), thus
confining the broadcast to a specific domain.

ES-3124 Series User’s Guide

8.2 Automatic VLAN Registration

GARP and GVRP are the protocols used to automatically register VLAN membership across
switches.

8.2.1 GARP

GARP (Generic Attribute Registration Protocol) allows network switches to register and de­register attribute values with other GARP participants within a bridged LAN. GARP is a
protocol that provides a generic mechanism for protocols that serve a more specific
application, for example, GVRP.

8.2.1.1 GARP Timers

Switches join VLANs by making a declaration. A declaration is made by issuing a Join
message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration timeout values.

8.2.2 GVRP

GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network. Enable this
function to permit VLANs groups beyond the local switch.

Please refer to the following table for common IEEE 802.1Q VLAN terminology.

8.3 Port VLAN Trunking

Enable VLAN Trunking on a port to allow frames belonging to unknown VLAN groups to
pass through that port. This is useful if you want to set up VLAN groups on end devices
without having to configure the same VLAN groups on intermediary devices.

Refer to the following figure. Suppose you want to create VLAN groups 1 and 2 (V1 and V2)
on devices A and B. Without VLAN Trunking, you must configure VLAN groups 1 and 2 on
all intermediary switches C, D and E; otherwise they will drop frames with unknown VLAN
group tags. However, with VLAN Trunking enabled on a port(s) in each intermediary switch
you only need to create VLAN groups in the end devices (A and B). C, D and E automatically
allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those
switches) to pass through their VLAN trunking port(s).
