CHAPTER 1
Introducing the OMC
This chapter introduces the OMC and the ways you can manage the OMC.
1.1 Overview
The OLT-2300 is a manageable optical line terminal (OLT), which is capable of providing
network access to customers at distances up to 20 km.
The OLT-2300 allows service providers to easily implement FTTH (Fiber To The Home)
infrastructure offering reliable high-speed network access to their subscribers over optical
fiber through ONUs (Optical Network Units).
The following shows an example network.
Figure 1 Network Example
Ethernet
The OMC-2301 (GEPON OLT Management Card) centralizes the management of all of the
GEPON OLT line cards. You can configure and maintain the OLT line cards through the OLT
management card; thus eliminating the need to connect to each line card individually.
With its built-in web configurator, managing and configuring the OMC is easy. In addition, the
OMC can also be managed via Telnet, a terminal emulator program on the console port, or by
third-party SNMP management.
1.2 Applications
In the following figure shows an FTTH (Fiber to the Home) examples using the OLT-2300.
The OLT-2300 is located at the Central Office (CO) and connected to the Internet. Three
ONUs at the residential homes connect to a fiber port on the OLT-2300 through a fiber splitter.

1.3 Ways to Manage the OMC
Use any of the following methods to manage the OMC.
• Web Configurator. This is recommended for everyday management of the OMC using a
(supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP for firmware upgrades and configuration backup/restore.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this
User’s Guide.
1.4 Good Habits for Managing the OMC
Do the following things regularly to make the OMC more secure and to manage the OMC
more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
28
OMC-2301 User’s Guide
Chapter 1 Introducing the OMC
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the OMC to its factory default
settings. If you backed up an earlier configuration file, you would not have to totally reconfigure the OMC. You could simply restore your last configuration.

The ALM port has input pins and output pins.
Connect the alarm input pins to another piece of equipment so it can notify the OMC-2301 of
an alarm. Connect the alarm output pins to another piece of equipment so the OMC-2301 can
notify it of an alarm.
The OMC-2301 signals an alarm when it detects an alarm on the ALM input pins or in the
OMC system (for example, the voltage or temperature is outside the normal range). To signal
an alarm, the OMC opens the circuit for pins 1 and 6 (the common pin) and closes the circuit
for pins 2 and 6.
A closed circuit on a pair of alarm input pins indicates an alarm. Pins 3 and 7 are alarm input I.
Pins 4 and 8 are alarm input II. Pins 5 and 9 are alarm input III.

you can log in.
40
OMC-2301 User’s Guide
Chapter 3 The Web Configurator
Any of the following could also lock you and others out from using out-of-band management
(managing through the console port or management port).
1 Misconfiguring the text configuration file.
2 Forgetting the password and/or management IP address.
3 Preventing all services from accessing the OMC.
4 Incorrectly configuring the access control settings.
5 Changing a service port number but forgetting it.
" Be careful not to lock yourself and others out of the OMC.
3.5 Resetting the OMC
If you lock yourself (and others) from the OMC or forget the administrator password, you will
need to reload the factory-default configuration file or reset the OMC back to the factory
defaults.
3.5.1 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 115200bps 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 default out-of-band management IP address to 192.168.0.1.
To upload the configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See
Section 2.3.1 on page 32 for details.
2 Disconnect and reconnect the OMC’s power to begin a session. When you reconnect the
OMC’s power, you will see the initial screen.

CHAPTER 4
Initial Setup Example
This chapter shows how to set up the OLT to provide Internet access to an ONU using the
default service profiles.
4.1 Overview
You need to test the connection between an ONU and the OLT in your network before
deploying your PON. You should already have a network with Internet access, a DHCP server
and a Gigabit switch.
In this example, you set up a simple PON network using an OLT, an ONU and a computer.
Once connected, the default profile settings on the OMC allow you to access the Internet
through the ONU. For the test network, you create a service profile on the OMC with the predefined 100Mbps bandwidth limit and apply it to the ONU.
Figure 11 Initial Setup: Network Example
ONU
PON 1
The following outlines the procedure for the initial setup.
• Connect the devices to set up a simple network.
• Create a service profile with the pre-defined bandwidth setting.
• Test the Internet connection from the ONU.
4.2 Connecting the Devices
Follow the steps below to connect the devices for the simple test network.
1 Insert an OLC-2301 in the first slot of the OLT 2300.
2 Connect the Gigabit Ethernet port on the OLC-2301 to a Gigabit port on a switch that
has access to the Internet.

Chapter 4 Initial Setup Example
" On the OLC-2301, the Gigabit Ethernet port connects only at 1000 Mbps.
3 Connect an ONU to the PON port on the OLC-2301.
4 Turn on the connected devices and check the LEDs on the OLC-2301. The LEDs for the
PON and the Ethernet port should be on.
4.3 Creating a Service Profile
Log into the OMC for management and create a service profile for the ONU. The service
profile is to use a pre-defined connection profile to limit the upstream and downstream
bandwidths to 100 Mbps.
1 Connect your computer to the MGMT port and set your computer to use a static IP
address in the range 192.168.0.2 ~ 192.168.0.254 with a subnet mask of 255.255.255.0.
2 Open a web browser and enter the management IP address of the OMC. The default is
192.168.0.1.
3 Enter the login username (“admin” is the default) and password (“1234” is the default)
and Click OK.
4 The Status screen displays.
Click PON Port 101 to
display the EPON Info
screen and check the MAC
address of the ONU.
" The digit(s) before 0 in a port number corresponds to the card slot on the OLT,
and the last digit denotes the port type (1 for PON port and 2 for uplink port).
5 Click Basic Setting > ONU Setup.
6 In the EPON ONU Setup screen, create a service profile for the ONU by clicking the
ONU name “Default” of Port 101 in the table below. Enter a new descriptive name in
the ONU Name field (for example, “TestSetup”).
7 In the MAC Address field, select the second radio button and the ONU’s MAC address
from the drop-down list box.

9 The OMC automatically applies the settings to the ONU. Display the EPON Info screen
again to check the settings (click Status > PON Port 101).
You should see that the upstream and downstream bandwidths for the ONU are set to
100 Mbps.
4.4 Testing the Internet Connection
In this section, you test Internet access through the ONU as a subscriber.
1 Connect your computer to the Ethernet port on the ONU.
" Make sure the computer is set to use a dynamic IP address.
2 Open a web browser and enter any web site address (for example, www.zyxel.com).
When the web site displays, you have successfully accessed the Internet through the
PON.

Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer
memory causing packet discards and frame losses. Flow control is used to regulate
transmission of signals to match the bandwidth of the receiving port.
The OMC uses IEEE802.3x flow control in full duplex mode and back pressure flow
control in half duplex mode.
IEEE802.3x flow control is used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending signals when the receiving port
memory buffers fill.

6.6 IGMP Snooping
The OLT can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets
transferred between IP multicast routers/switches and IP multicast hosts to learn IP multicast
group membership information. It checks IGMP packets passing through it, picks out the
group registration information, and configures multicasting accordingly. IGMP snooping
allows the OLT to learn multicast groups without you having to manually configure them.
Chapter 6 Basic Setting
The OLT forwards multicast traffic destined for multicast groups (that it has learned from
IGMP snooping or that you have manually configured) to ports that are members of that
group. The OLT discards multicast traffic destined for multicast groups that it does not know.
IGMP snooping generates no additional network traffic, allowing you to significantly reduce
multicast traffic passing through your OLT.
6.6.1 IGMP Proxy
To allow better network performance, you can use IGMP proxy instead of a multicast routing
protocol in a simple tree network topology.
In IGMP proxy, an upstream interface is the port that is closer to the source (or the root of the
multicast tree) and is able to receive multicast traffic. There should only be one upstream
interface (also known as the query port) on the system to limit bandwidth use. A downstream
interface is a port that connects to a host (such as a computer). A query VLAN determines
which ports are downstream interfaces.
The following figure shows a network example where A is the multicast source while
computers 1, 2 and 3 are the receivers. In the figure A is connected to the upstream interface
and 1, 2 and 3 are connected to the downstream interface.
OMC-2301 User’s Guide

The system will not respond to IGMP join and leave messages on the upstream interface. The
system only responds to IGMP query messages on the upstream interface. The system sends
IGMP query messages to the hosts that are members of the query VLAN.
The system only sends an IGMP leave messages via the upstream interface when the last host
leaves a multicast group.
The Ethernet port on the line card acts as the upstream interface. By default, the PON port is
set as a downstream interface.

" The OLT does not allow a PON port to send multicast traffic (except static
multicast traffic) to an uplink port. Only the uplink port can forward multicast
traffic to the PON port.
6.7 DBA (Dynamic Bandwidth Allocation)
In an EPON network, to prevent network congestion, dynamic bandwidth allocation allows
the OLT to quickly re-assign unused bandwidth based on traffic requirements. The OLT
periodically broadcasts discovery messages to all ONUs. The ONUs then can register and send
report messages to request bandwidth for data transmission. The OLT bases on the registered
ONU’s RTT (Round Trip Time) and bandwidth request to decide when and how long the ONU
can transmit data. Bandwidth re-assignment can be for an ONU or for the priority-level
queues. In addition to reassigning bandwidth on the go, DBA helps to ensure quality of service
on the network.
" A PON port allows only one ONU to transmit data at a time.
64
OMC-2301 User’s Guide
By default, the OLT uses the Plato DBA algorithm that allows you to fully utilize bandwidth in
your network environment. With the Plato DBA algorithm, the OLT assigns bandwidth based
on report messages from ONUs, link priority and delay tolerance. In addition, the OLT
guarantees a minimum upstream bandwidth and provides the best-effort maximum upstream
bandwidth.

Upstream/Downstream Priority Queue Assignment
IEEE 802.1p defines up to 8 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 following fields to configure the priority level-to-physical queue
mapping.
On the ONUs, traffic assigned to higher index queues gets serviced faster while traffic in lower index
queues may be 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 IEEE 802.1p).
Priority 7 Typically used for network control traffic such as router configuration messages.

6.11 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.
" VLAN is unidirectional; it only governs outgoing traffic.
See Chapter 8 on page 83 for information on IEEE 802.1Q tagged VLANs.

Chapter 6 Basic Setting
6.11.1 Port-based VLANs
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the device on which they were created.
6.12 4-Port ONU Profile
Use the 4-Port ONU Profile screen to create or edit a profile that contains connection and
port-based VLAN settings for a 4-port ONU. Once you have set the profile settings, you can
apply it to the ONU in the ONU Setup screens (refer to Section 6.9 on page 67).
Your OMC comes with a “Default” profile containing settings that work in most network
environment.
When you create a profile having the same name as an existing profile, the previous settings
will be replaced in the existing profile.

Classifier Filter Profile
This chapter shows you how to configure the Classifier Filter Profile screen to filter packets.
7.1 Overview
In addition to filtering packets based on the MAC address (refer to Section 11.3 on page 102),
you can configure the ONU to forward or drop packets based on the VLAN ID, protocol
number, Ethernet type, source or destination IP address or the TCP/UDP source port number.
7.2 Classifier Filter Profile Setup
Use the Classifier Filter Profile screen to configure actions on the grouped traffic flow.
Your OMC comes with two pre-defined classification filter profiles. The “Default” filter
profile forwards all packets (tagged or untagged). As the name implies, the “Stop_traffic”
filter profile discards all packets, thus preventing the subscriber from sending traffic through
the ONU.

CHAPTER 8
VLAN Profile
This chapter describes how to configure VLAN profiles for the ONUs to manage VLAN
traffic.
8.1 Introduction to IEEE 802.1Q Tagged VLANs
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 device 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 devices
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).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet
switching devices. 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 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
VLAN group ID (or VID) is a unique number than identifies a VLAN. A port VID (PVID) is
the VID associated to a physical port. A PVID defines the VLAN group to which a port
belongs.
The ONU is capable of passing tagged or untagged frames. To forward a frame from an
802.1Q VLAN-aware device to an 802.1Q VLAN-unaware device, the ONU first decides
where to forward the frame and it may then strip off the VLAN tag or add a new VLAN tag.
To forward a frame from an 802.1Q VLAN-unaware device to an 802.1Q VLAN-aware
device, the ONU first decides where to forward the frame, and then inserts a VLAN tag
reflecting the ingress port's default VID.
OMC-2301 User’s Guide
83
Chapter 8 VLAN Profile
The egress (outgoing) port(s) of a frame is determined on the combination of the destination
MAC address and the VID of the frame. For a unicast frame, the egress port (based on the
destination MAC address) must be a member of the VID, also; otherwise, the frame is
blocked. 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.
Whether to tag an outgoing frame depends on the setting of the egress port on an individual
VLAN and port basis (remember that a port can belong to multiple VLANs). If the tagging on
the egress port is enabled for the VID of a frame, then the frame is transmitted as a tagged
frame; otherwise, it is transmitted as an untagged frame.
8.2 VLAN Stacking
A service provider can use VLAN stacking to allow it to distinguish multiple customers
VLANs, even those with the same (customer-assigned) VLAN ID, within its network.
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.
A service provider’s customers may require a range of VLANs to handle multiple
applications. A service provider’s customers can assign their own inner VLAN tags on ports
for these applications. The service provider can assign an outer VLAN tag for each customer.
Therefore, there is no VLAN tag overlap among customers, so traffic from different customers
is kept separate.
8.2.1 VLAN Stacking Example
In the following example figure, both A and B are Service Provider’s Network (SPN)
customers with VPN tunnels between their head offices and branch offices respectively. Both
have an identical VLAN tag for their VLAN group. The service provider can separate these
two VLANs within its network by adding tag 37 to distinguish customer A and tag 48 to
distinguish customer B at edge device 1 and then stripping those tags at edge device 2 as the
data frames leave the network.

Type Priority VID
Type is a standard Ethernet type code identifying the frame and indicates that whether the
frame carries IEEE 802.1Q tag information. SP TPID (Service Provider Tag Protocol
Identifier) is the service provider VLAN stacking tag type. Many vendors use 0x8100 or
0x9100.
Priority refers to the IEEE 802.1p standard that allows service providers to prioritize traffic
based on the class of service (CoS) the customer has paid for.
• On the OMC, configure priority level on inner IEEE 802.1Q in the VLAN Profile screen.
• "0" is the lowest priority level and "7" is the highest.
VID is the VLAN ID. SP VID is the VID for the second (service provider’s) VLAN tag.

CHAPTER 9
Priority Profile
This chapter describes how you can change packet priorities using the Priority Profile screen.
9.1 Priority Profile Overview
Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay,
and the networking methods used to control the use of bandwidth. Without QoS, all traffic data
is equally likely to be dropped when the network is congested. This can cause a reduction in
network performance and make the network inadequate for time-critical application such as
video-on-demand.
To ensure QoS on packets between layer 2 (L2) and layer 3 (L3) networks, you can configure
a priority profile to map TOS (L3) precedence bits to the COS (L2) value. Each COS value is
then mapped to the physical queue you specify in the EPON Common Setup screen. The
The OMC determines the COS value of a packet using one of the following methods:
• Using the IEEE 802.1p priority level in the VLAN tag.
• Using the port’s default priority setting.
• Mapping the TOS bits.
In addition to configuring TOS-COS mappings, you can do the following to ensure QoS on the
network using a priority profile:
• Group traffic based on the Ethernet type, VLAN group or protocol number. Then assign a
VLAN priority and queue to the classified traffic.
• Associate a priority profile to a service profile.
9.2 Configuring a Priority Profile
Click Advanced Application > Priority Profile to display the configuration screen. Use this
screen to change the precedence bits (TOS-COS mappings) and VLAN priority and assign
specified packets to queues. Once you have configured a priority profile, associate it to a
service profile to apply to an ONU.

Static MAC Forward Setup
Use these screens to configure static MAC address forwarding.
10.1 Overview
A static MAC address is an address that has been manually entered in the MAC address table.
Static MAC addresses do not age out. When you set up static MAC address rules, you are
setting static MAC addresses for a port. This may reduce the need for broadcasting.
10.2 Static MAC Forwarding Status
You can view the number of static MAC forwarding rules you configure per Ethernet port in
the Static MAC Forwarding Status screen. Click Advanced Application > Static MAC
