4. 2. First log in www.dasannetworks.eu
With default configuration OLT have not configured any IP interface, so first log in must be done through CONSOLE port:
Speed: 9600, Data bits: 8, Stop bits: 1, Parity: None, Flow Control: XON/XOFF
LOGIN: admin
PASSWORD: <empty>
Privileged EXEC View Mode - When you log in to the switch, the CLI will start with Privileged EXEC View mode which is a read- only mode. In this mode, you can see a system configuration and information with several commands.
Privileged EXEC Enable Mode - To configure the switch, you need to open Privileged EXEC Enable mode with the enable command, then the system prompt will changes from SWITCH> to SWITCH#.
Global Configuration Mode - In Global Configuration mode, you can configure general functions of the system. You can also open another configuration mode from this mode. To open Global Configuration mode, enter the configure terminal command, and then the system prompt will be changed from SWITCH# to SWITCH(config)#. 
Helpful:
TAB – press to finish command
SWITCH(config)# show ? - When you input the question mark <?>, you can see available commands used in this mode and variables following after the commands.
SWITCH(config)# sh? - you can find out commands starting with a specific alphabet.
SWITCH(config)# sh vl - several commands can be used in the abbreviated form.
The same is on all DASAN OLTs: V5812G|V5824G|V8240

The same is on all DASAN OLTs: V5812G|V5824G|V8240

6. 4. Management interface and default route
To access to the OLT from remote place (using telnet or ssh) You have to configure IP interface on the OLT.
To assign an IP address to an interface, you need to enable the interface first. If the interface is not enabled, you cannot access it from a remote place, even though an IP address has been assigned.
SWITCH> enable
SWITCH# configure terminal
SWITCH(config)# interface mgmt
SWITCH(config-if)# no shutdown
After enabling an interface, assign an IP address. To assign an IP address to a network interface, use the following command:
SWITCH(config-if)# ip address /24
SWITCH(config-if)# exit
To display an interface status and configuration, use the following command:
SWITCH(config)# show ip interface brief
To configure a default gateway, use the following command
SWITCH(config)# ip route default GATEWAY_IP
You can configure IP address also on other interface – on each VLAN and access it through OLT uplink ports – e.g. if there is vlan 100 created:
SWITCH(config)# interface 100
SWITCH(config-if[100])# ip address /24
SWITCH(config-if[100])# no shutdown
VLAN and interface configuration You can find on one of next presentation

7. 5. How to check system software version
The DASAN OLTs (V5812G|V5824G|V8240) supports the dual system software functionality (OS1 and OS2), which you can select applicable system software stored in the system according to various reasons such as the system compatibility or stability. To upgrade the system software, FTP or TFTP server must be set up first! Using the copy command, the system will download the new system software from the server to the defined OS.
To check OLT system software use below command:
SWITCH> enable
SWITCH# show flash
Default – default OS after OLT reboot
Running – active OS
SWITCH# show version
To check and get actual firmware version please log in to: and download.
Otherwise You can contact with:

8. 6. OLT system software upgrade – V5812G|V5824G
To upgrade the system software of the switch, use the following commands:
1. IP address should be configured on OLT interface and access to the FTP server should be available
2. Check which OS is NOT ACTIVE (without „running” mark) – in this example OS1 is STANDBY OS
2. Download new firmware from FTP/TFTP server to the OLT OS1:
SWITCH# copy ftp os download os1 OR
SWITCH# copy tftp os download os1
3. Set default os to OS1:
SWITCH# default-os os1
4. Save configuration:
SWITCH# write memory
5. Reload the OLT:
SWITCH# reload

9. 7. OLT system software upgrade – V8240 (one SFU installed)
The OLT V8240 provides:
10 slots for SIU (Subscriber Interface Unit) – for installing GPON service cards
2 slots for NIU (Network Interface Unit) – for installing uplink cards
2 slots for SFU (Switch Fabric Unit)
The SFU, the switching fabric unit, plays the important role of switching the traffic and managing all components. The SFU processes the incoming traffic and forwards them to the proper interfaces via the main switching fabric. It also contains RS232 console access and the out- of-band management interface to manage the system on the front panel of the SFU.
To upgrade the system software of the switch (with only one installed),
use the following commands:
On V8240 You must upgrade SFU and all SIU cards (described later)
IP address should be configured first on OLT interface and access to the FTP server should
be available
2. Check which OS is NOT ACTIVE (without „running” mark) – in this example OS1
3. Download new firmware from FTP/TFTP server to the OLT OS1:
SWITCH# copy ftp os download os1 OR
SWITCH# copy tftp os download os1
4. Set default os to OS1:
SWITCH# default-os os1
5. Save configuration:
SWITCH# write memory
6. Reload the OLT:

10. 8. OLT system software upgrade – V8240 (redundant SFU installed)
When dual SFUs are used, the system decides the running mode of SFUs between active and standby. The first inserted and booted SFU runs in active mode and the other SFU that follows runs in standby mode. The following diagram illustrates SFU redundancy scheme used for the V8240.
Both SFUs are internally linked to IUs including SIU and NIU. They receive traffic from IUs and update their own Forwarding Database ( FDB) in the same manner so that they can keep identical data to make a forwarding decision. However, only the active SFU can send traffic back to the OIUs; the standby SFU can just receive traffic for address learning.
In a redundancy scenario, only the active SFU is working in the system and contains user configurations via SNMP or CLI and dynamically-learned state information such as DHCP snooping, IGMP snooping, L3 protocols, STP states, etc. But the standby SFU doesn’t have that information. Thus, there is a mechanism to synchronize between the active SFU and standby SFU. The active SFU periodically sends state information to the standby SFU through an interlinked 100MB channel between them.
T o display the status of SFU, use the following command:
SWITCH# show redundancy status
To upgrade the system software of the switch (with redundant SFU) WITHOUT OLT RELOAD, do below steps:
In this example:
SFU1 – ACTIVE
SFU2 – STANDBY
IP address should be configured on mgmt interface and FTP server should be available
Connect two links to both MGMT interfaces (on SFU1 and SFU2)
Check which OS is NOT ACTIVE (without „running” mark) – in this example OS1
Synchronize the configuration data between SFUs for redundancy control,
use the following command:
SWITCH# copy configsync all
Save configuration:
SWITCH# write memory
Download new firmware from FTP/TFTP server to the OLT OS1:
SWITCH# copy ftp os download os1 (new firmware will be downloaded to both SFUs)
Set default os to OS1 (with downloaded new firmware):
SWITCH# default-os os1
Switch to the STAND BY SFU2 (after that action, SFU1 will be rebooted with new firmware - SFU1 will be now STANDBY, SFU2 will be ACTIVE )
SWITCH# switchover
Wait until SFU1 will be ready and switch back to SFU1(which already have new software) – after that also SFU2 will be rebooted and start with new firmware:
SWITCH# switchover (if STANDBY SFU will be not ready You will see on console: % The standby SFU is not ready.
DONE

11. 9. OLT Subscriber Interface Unit (SIU) upgrade – V8240 (1)
1) SLOTs UNBLOCKING AND PLANNING
By default, all of SIU and NIU slots are in admin ‘locked’ state that IUs are unable to operate normally even though they are properly inserted into the shelf with power-up. To activate a specific IU, you have to change the admin state of a slot from ‘locked’ to ‘unlocked’ by the command. This means that a subscriber or network service card can only be active when its slot is configured with a planned IU type and changed to ‘unlock’ state by the command. and standby. So before SIU upgrade we must unlock and plan slots.
To unlock and plan IU slots, do below steps:
After installing in the V8240 chassis, perform the following steps for each IU to be properly operated
On this example we will unlock and plan:
SIU 1 and plan with siu-gpon4 card (4xGPON)
NIU 1 and plan with niu-10ge2plus (2xXFP, 4xSFP)
Configure a slot for the specified IU type, use the following command:
SWITCH> enable
SWITCH# configure terminal
SWITCH(config)# slot planning siu 1 siu-gpon4
SWITCH(config)# slot planning niu 1 niu-10ge2plus
Change the admin state to ‘unlock’ for each slot to activate the equipped IU:
SWITCH(config)# slot unlock siu 1
SWITCH(config)# slot unlock niu 1
To display a status of slot information, use the following command):
SWITCH(config)# show slot status siu SLOT_NUMBER
SWITCH(config)# show slot status niu SLOT_NUMBER
SWITCH(config)# show slot nos siu SLOT_NUMBER
SWITCH(config)# show slot system siu SLOT_NUMBER

12. 9. OLT Subscriber Interface Unit (SIU) upgrade – V8240 (2)
To upgrade the system software of a specific module, perform the following step-by-step instruction:
