ZTE C6xx Titan OLT initial steps
In this post you'll find step by step instructions for initial OLT configuration and for setting up the IP connectivity of the ZTE TITAN C6xx Series OLTs. After completing these steps, you'll be ready to connect your OLT to SmartOLT.
1Connect to the OLT
Click to choose how you connect to the OLT
- Serial / Console: required for a factory-new C6xx. There is no factory IP address and usually no default account, so the first configuration is done over the serial console.
- Ethernet / Telnet or SSH: only for a C6xx that is already configured: it has a reachable IP address, an existing account, and Telnet or SSH enabled.
Serial / Console connection
From a PC (PuTTY)
- Use the original ZTE serial cable provided in the C6xx box. It has a special pinout: Cisco or Huawei console cables are NOT compatible. Connect it to the port labeled CON.
- If your PC has no serial port, use a USB-to-serial adapter.
- Find the COM port of the adapter in Windows Device Manager (Windows+X), under Ports (COM & LPT).
- In PuTTY, select Serial, enter the COM port and the speed. Set the other values under Connection > Serial:
- Speed: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
- Open the session and press Enter. If the OLT asks for a login, use its existing account. If the OLT has no account yet, stay on the serial console: you create the dedicated user in step 3.
Through a MikroTik
Use the MikroTik serial console port with a compatible cable to the OLT console port. Open a MikroTik Terminal through WinBox or SSH over the network.
- Free the serial port and open the serial session:
/system console disable [find where port=serial0] /system serial-terminal serial0
- Press Ctrl+A, release the keys, then press R to detect the baud rate automatically. Press Enter to reach the OLT console.
To close the serial session, press Ctrl+A, release the keys, then press Q.
Ethernet connection (Telnet or SSH)
Use this only when the OLT is already configured. A factory-new C6xx needs the serial console.
- Use the network path the OLT is already reachable on: the MGMT port if the IP address is configured there, or your existing in-band network. Do not change the cabling of an OLT that is already reachable.
- If you connect your PC directly to the OLT, configure on it a free IP address from the same subnet as the OLT IP address.
- Verify connectivity. You should receive replies.
ping [OLT IP address]
- Connect with PuTTY or from a terminal, using Telnet or SSH.
Telnet sends everything, including the password, as plain text. Use it only on a direct cable or a trusted management network. It works only if Telnet is enabled on the OLT. In PuTTY, select Telnet and enter the OLT IP address.
telnet [OLT IP address]
SSH encrypts the session. It works only if the SSH server is enabled on the OLT and the account is allowed to log in over SSH.
PuTTY: Enter the OLT IP address in Host Name (or IP address), select SSH, then click Open. Log in with your OLT username and password.
Terminal (OpenSSH): Run the command below in your computer's terminal.
ssh [username]@[OLT IP address]
- Log in with the existing account of the OLT.
Enter privileged mode
If the prompt ends with ">" instead of "#", enter enable. The default enable password is zxr10, unless it was changed. The prompt changes to ZXAN#.
ZXAN>enable
Password: zxr10
ZXAN#
Verify the status of the cards using the command: show card (following is an example)
ZXAN# show card Shelf Slot CfgType CardName Port HardVer Status --------------------------------------------------- 1 1 GFGH GFGH 16 V1.0.0 INSERVICE 1 2 GFGH GFGH 16 V1.0.0 INSERVICE 1 3 FCSDA FCSDA 0 V1.0.0 INSERVICE 1 4 SPUF 4 OFFLINE 1 5 SPUF SPUF 4 V1.0.0 INSERVICE 1 6 PRSF PRSF 0 V1.0.0 INSERVICE
2Configure an IP address on the mgmt_eth or VLAN interface
Select the interface of the management IP
Connect the OLT and the router with a LAN cable on the management port labeled MGMT. It is positioned in the same port group as the CLK, ALM and CON ports. The MGMT port is an isolated port for management purposes only and cannot carry customer traffic. It is also called the OOB (Out Of Band) management port.
ZXAN# conf t ZXAN(config)# interface mgmt_eth ZXAN(config-if)# ip address 10.200.0.2 255.255.255.0 ZXAN(config-if)# exit ZXAN(config)# exit
If you connected over Ethernet using the old IP address, reconnect on the new IP address 10.200.0.2.
Add the default gateway and save configuration:
ZXAN# conf t
ZXAN(config)# no ip route vrf mng 0.0.0.0 0.0.0.0
ZXAN(config)# ip route vrf mng 0.0.0.0 0.0.0.0 10.200.0.1
ZXAN(config)# exit
ZXAN# write
Write DB OK!
Building configuration...
....[OK].
ZXAN#
Check the routing table to confirm the default gateway was applied:
ZXAN# show ip forwarding route vrf mng
Dest Gw Interface Owner Pri Metric
*> 0.0.0.0/0 10.200.0.1 mgmt_eth Static 1 0
*> 10.200.0.0/24 10.200.0.2 mgmt_eth Direct 0 0
*> 10.200.0.2/32 10.200.0.2 mgmt_eth Address 0 0
3Create a local authentication template and a dedicated username/password
This user/pass will be used by SmartOLT to connect to your OLT.
conf t
aaa-authentication-template 2001
aaa-authentication-type local
exit
aaa-authorization-template 2001
aaa-authorization-type local
exit
system-user
authorization-template 1
bind aaa-authorization-template 2001
local-privilege-level 15
exit
authentication-template 1
bind aaa-authentication-template 2001
exit
user-name smartoltusr
bind authentication-template 1
bind authorization-template 1
password [a strong generated password]
exit
4Enable telnet
conf t
line telnet server enable
exit
write
At this stage, your OLT is ready to be interconnected with SmartOLT.
Open your SmartOLT site, go to Settings → OLTs → Add OLT, fill in the fields displayed, click Test connection, and then Save.
Other settings (If you use SmartOLT, these are configured automatically, no need to configure them manually):
conf t
auto-write everyday 19:00:00

ntp server 216.239.35.4 priority 2 version 4 unlock
ntp server 162.159.200.123 priority 3 version 4 unlock
