Service model in EasyMode
The EasyMode includes a prepared configuration for the network, a diagram of which is shown in Figure 5.
Figure 5 – EasyMode network diagram
Service model of this network:
- Internet service using IPoE technology. It is possible to add option 82 specified by you to DHCP packets.
- VLAN-on-service model. Subscribers of one service are in the same vlan.
- User isolation There is no connectivity between subscribers at the channel level.
- Dedicated multicast vlan. Unicast services: IPTV (Video-On-Demand, VoD) are spaced from multicast traffic.
- Multicast traffic is available for all ports of subscriber terminal.
EasyMode enabling and configuration
Enabling EasyMode will lose the current configuration. Save it if you may need it later.
EasyMode can be used with the values you specify or with default values.
Default configuration
Parameters to be applied by default:
IP address for LTP management | 192.168.1.2 |
Subnet mask | 255.255.255.0 |
Management VLAN | 1 |
Gateway in management network | none |
ACS VLAN (built-in TR-069 server) | 2 |
Internet VLAN | 100 |
VoIP VLAN | 200 |
VoD VLAN | 300 |
Multicast VLAN | 400 |
Option82 Circuit-Id | none |
Option82 Remote-Id | none |
To enable EasyMode with default values, you need to execute the easy-mode command. After that, a warning will be displayed stating that the current configuration of the device will be lost.
Please make sure that your access settings for the device match those that will be applied, or you have a connection using the console cable.
LTP-4X# easy-mode
Enabling easy-mode will delete current configuration. Are you sure? (y/n) y
Configured easy-mode...
Easy mode enable successfully
LTP-4X#
After that, you can proceed to sections 6.3 and 7 of this manual.
Custom configuration
You can change the settings of the LTP management interface, service VLANs and DHCP options of option 82 using the Wizard. In addition, you can quickly add already connected subscriber terminals and after completing the configuration, get a network ready for operation.
To start working with Wizard, you need to execute the easy-mode wizard command. After that, a warning will be displayed stating that the current configuration of the device will be lost.
LTP-4X# easy-mode wizard
Enabling easy-mode will delete current configuration. Are you sure? (y/n) y
Customize easy-mode configuration:
< … >
VLAN configuration
Specify the VLANs you want to use for the services. VLAN data will be automatically registered tagged to all Ethernet ports, with the exception of VLANs for the built-in ACS server.
If you are satisfied with all the default values, you can refuse the change by responding N to the invitation to change. If you are satisfied with the default value for a single service, you can skip input by simply pressing <Enter>.
As an example, change the VLAN as follows:
ACS VLAN | 2 (without change) |
Internet VLAN | 1001 |
VoIP VLAN | 1002 |
VoD VLAN | 1003 |
Multicast VLAN | 3 |
Current VLAN configuration:
ACS VLAN ID: 2
Internet VLAN ID: 100
VoIP VLAN ID: 200
VoD VLAN ID: 300
Multicast VLAN ID: 400
Do you want to change VLAN configuration? (y/N): y
Enter ACS service VLAN ID (leave blank for default) [2]:
Enter Internet service VLAN ID (leave blank for default) [100]: 1001
Enter VoIP service VLAN ID (leave blank for default) [200]: 1002
Enter VoD service VLAN ID (leave blank for default) [300]: 1003
Enter Multicast VLAN ID (leave blank for default) [400]: 3
Configuration of the LTP management interface
In the next section, you can change the access settings for LTP. If you are satisfied with the default value, reply N to the change prompt. If you are satisfied with the default value for a single parameter, you can skip input by simply pressing <Enter>.
As an example, change the management settings as follows:
Management IP | 10.189.55.19 |
Management mask | 255.255.255.0 |
Management gateway | 10.189.55.254 |
Management vid | 189 |
Current management settings: IP: 192.168.1.2 Mask: 255.255.255.0 Gateway: 0.0.0.0 Management VLAN ID: 1 Do you want to change management configuration? Attention, it may cause disconnection from remote sessions! (y/N): y Enter management IP (leave blank for default) [192.168.1.2]: 10.189.55.19 Enter management mask (leave blank for default) [255.255.255.0]: Enter management gateway (leave blank for default) [0.0.0.0]: 10.189.55.254 Enter management VLAN ID (leave blank for default) [1]: 189
It is not allowed to use one VLAN for device management and for the built-in ACS server. When you try to configure this, a warning will be displayed:
Error: ACS VLAN intersects with management VLAN. Try again.
In this case, you need to select a different VLAN number.
It is not allowed to use one subnet IP for the device management and for the built-in ACS server.
The built-in ACS uses the address 192.168.200.1/21. When you try to configure this, a warning will be displayed:
Error: ACS network intersects with management network. Try again.
In this case, you need to select a different IP subnet.
DHCP Relay Agent (option 82) configuration
The last configuration step – DHCP option 82 configuration for substitution into packets from subscribers. By default, option substitution is disabled. If option 82 is not used on your network, you can skip configuring it by answering N to the prompt to change.
When enabling option expansion, the following values of the Circuit-Id and Remote-Id suboptions are used:
Circuit-Id | %HOSTNAME%%PONSERIAL%%VLAN0% |
Remote-Id | - |
When configuring the values of options, tokens are used, in place of which the corresponding values will be substituted. The rest of the text will be left unchanged. Tokens used:
%HOSTNAME% | LTP terminal name |
%MNGIP% | Mangement IP address |
%GPON-PORT% | ONT GPON port number |
%ONTID% | ONT number on GPON port |
%PONSERIAL% | ONT serial number |
%GEMID% | GEM port number |
%VLAN0% | External (or single) Vlan |
%VLAN1% | Internal (or single) Vlan |
%MAC% | MAC address |
%OLTMAC% | OLT`s MAC address |
%OPT60% | Option 60 from the original packet |
%OPT82_CID% | Circuit-Id of the option 82 from the original packet |
%OPT82_RID% | Remote-Id of the option 82 from the original packet |
%DESCR% | ONT description from configuration |
If the default values of the Circuit-Id and Remote-Id suboptions suit you, refuse to make changes by replying to N at the invitation to change.
As an example, suppose that the LTP IP address is 10.189.55.19, ONT is connected to 1 GPON port with ID 15. Set the settings in such a way as to obtain the following values:
Circuit-Id | 1-15 |
Remote-Id | 10.189.55.19 |
Do you want to use option 82? (y/N): y
Current configuration dhcp-ra overwrite-option 82:
Circuit id: %HOSTNAME%-%PONSERIAL%-%VLAN0%
Remote id: -
Do you want to setup Option 82 format?
(answer No for default option) (y/N): y
Enter Circuit ID (leave blank for empty option): %GPON-PORT%-%ONTID%
Enter Remote ID (leave blank for empty option): %MNGIP%
Saving configuration
After applying the new configuration, you will see a message:
Configured easy-mode... Easy mode enable successfully
Save the configuration changes by executing the save command. After that, the configuration will be saved in non-volatile memory.
LTP-4X# save ........ Configuration successfully saved to file
Adding new ONTs
Automatic ONT activation configuration
In the simplified setup mode, the ONT auto-activation mode is enabled, and the required ONT configuration is applied automatically from the corresponding auto-activation template. These templates were created when EasyMode was enabled. For NTU-1, which are controlled using OMCI protocol only, the easy-ONT template is used. For all other ONTs, the easy-RG template is used.
LTP-8X# show running-config gpon olt configure terminal gpon olt auto-activation ont enable gpon olt auto-activation ont default template "easy-RG" gpon olt auto-activation ont type NTU-1 template "easy-ONT" exit commit LTP-8X#
Manual ONT activation
After enabling and configuring EasyMode to add new connected ONTs to the configuration, you need to:
Disable ONT auto-activation
LTP-8X(config)# no gpon olt auto-activation ont enable
Find out the ONT serial numbers, their types, and the GPON port numbers to which they are connected. If during the setup process you want to immediately activate the connected subscriber terminals, you will need a list of their serial numbers and the GPON ports to which they are connected. You can get a list of all inactive ONTs using the show interface ont 0-7 unactivated command (for LTP-4X, use show interface ont 0-3 unactivated).
LTP-4X# show interface ont 0-3 unactivated GPON-port 0 has no unactivated ONTs GPON-port 1 has no unactivated ONTs ----------------------------------- GPON-port 2 ONT unactivated list ----------------------------------- ## Serial ONT ID GPON-port Status ... 1 454C545862000100 n/a 2 UNACTIVATED ... 2 454C545866000101 n/a 2 UNACTIVATED ... GPON-port 3 has no unactivated ONTsDefine free ONT IDs for this GPON port. To do this, run the show interface ont 2 unconfigured command.
LTP-4X# show interface ont 2 unconfigured GPON-port 2 ONT unconfigured list: 2-127 Total ONT count: 126 LTP-4X#
Switch to the configuration mode. For this use the configure terminal command.
LTP-4X# configure terminal LTP-4X(config)#
Select one of the free ONT IDs and switch to the ONT configuration mode. For this, execute the interface ont 2/2 command.
LTP-4X(config)# interface ont 2/2 LTP-4X(config)(if-ont-2/2)#
Specify the serial number of the custom ONT and the template used for it: easy-ONT for NTU-1 and easy-RG for all other. Then exit the ONT configuration mode.
LTP-4X(config)(if-ont-2/2)# serial 454C545862000100 LTP-4X(config)(if-ont-2/2)# template easy-ONT LTP-4X(config)(if-ont-2/2)# exit LTP-4X(config)#
Repeat steps 4-5 for all remaining ONTs.
LTP-4X(config)# interface ont 2/3 LTP-4X(config)(if-ont-2/3)# serial 454C545866000101 LTP-4X(config)(if-ont-2/3)# template easy-RG LTP-4X(config)(if-ont-2/3)# exit
Exit the configuration mode, apply the changes made with the commit command and save them in non-volatile memory with the save command.
LTP-4X(config)# exit LTP-4X# commit Changes successfully commited (2 chunks) LTP-4X# save ........ Configuration successfully saved to file LTP-4X#
After applying the configuration, the subscriber terminals will reboot with the new configuration. The old one will be deleted.
Configuration of VoIP on the ONT
Consider configuring RG ONT parameters using the internal ACS using the example of VoIP settings. For more information about working with ACS, refer to the 'Eltex ACS User manual', which can be found at https://eltex-co.com/catalog/management/.
Configure for the ONT 454C545866000101 the number 101 with the secret password on the sip server sip.test.pon. For this, do the following:
Execute acs command to operate with the built-in ACS server.
LTP-4X# acs LTP-4X(acs)#
Switch to the ONT configuration mode and select the desired ONT by serial number using the ont and ont 454C545866000101 commands.
LTP-4X(acs)#ont LTP-4X(acs-ont)#ont 454C545866000101 LTP-4X(acs-ont-sn='454C545866000101')#

LTP-4X(acs-ont-sn='454C545866000101')#exit LTP-4X(acs-ont)#exit LTP-4X(acs)#exit LTP-4X#
Using a predefined ONT configuration without using EasyMode
If you are not satisfied with the proposed EasyMode service model, you can only use the predefined ONT configuration by configuring LTP by yourself, according to your needs.
The predefined configuration includes:
- Internet service
IPoE interface in u-VLAN 10 with DHCP client and IGMP proxy. By the LAN side: ports 1 and 2 for ONT with 4 ports (NTU-RG), or port 1 for ONT with 2 ports (NTU-2V(C), NTU-2W). This interface will be the default route for clients connected to LAN ports. Upstream IGMP reports will also be sent in this VLAN. To send them to the multicast VLAN use the ip igmp proxy command on LTP.
- VoIP service
IPoE interface in u-VLAN 20. The built-in SIP client operates from this interface.
- VoD service
Bridge between u-VLAN 30 and LAN ports 3, 4 for ONT with 4 ports (NTU-RG), or port 2 for ONT with 2 ports (NTU-2V (C), NTU-2W).
To activate a predefined configuration, you must add the easy-mode command to the ONT settings or to the template used.
LTP-4X# configure terminal LTP-4X(config)# interface ont 2/2 LTP-4X(config)(if-ont-2/2)# easy-mode LTP-4X(config)(if-ont-2/2)# exit LTP-4X(config)# exit LTP-4X# commit Changes successfully commited (1 chunk)
After that, the subscriber terminal will reboot with a predefined configuration. The old one will be deleted.
To roll back the configuration to the factory settings, you must execute the no easy-mode command and then reset to the factory settings with the send omci restore interface ont command.
LTP-4X# configure terminal
LTP-4X(config)# interface ont 2/2
LTP-4X(config)(if-ont-2/2)# no easy-mode
LTP-4X(config)(if-ont-2/2)# exit
LTP-4X(config)# exit
LTP-4X# commit
Changes successfully commited (1 chunk)
LTP-4X# send omci restore interface ont 2/2
[ONT2/2] was successfully restored to default config and rebooted
