ZTE C6xx Titan OLT initial configuration


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.

Step one: Connect to the OLT with the provided serial cable, using a Serial-to-USB converter if necessary.

There is no factory IP address and usually no default user/pass like zte/zte, so the initial configuration must be done by serial terminal. For this connection you will use the port labeled CON.

The default password for the "enable" privilege is zxr10 .

Use the original ZTE serial cable provided in the C6xx box, it has a special pinout. Cisco or Huawei cables are NOT compatible. Connect the cable to the CON port of the OLT. Connect the other end to your PC, most likely using the Serial-to-USB converter. You can use PuTTY serial terminal to connect to the OLT, using the parameters 9600-8-N-1. To find out the correct COM port used by the Serial-USB converter, take a look in the operating system Device Manager (Windows+X) -- on the Ports (COM&LPT) section.

At this moment, also connect the OLT and the Router with a LAN cable, using the management labeled MGMT. It is positioned in the same port group with the CLK, ALM and CON ports.

The MGMT port is an isolated port, designed for management purposes only. This port cannot be used to transport the traffic of the customers - it is also called OOB (Out Of Band) management port.

This is how the console should appear when you connect:

[Ctrl-A is the prefix key]

Welcome to ZXAN product C300 of ZTE Corporation

Last login time is 08.20.2020-13:29:54-UTC, 0 authentication failures
happened since that time.

Password: zxr10

Step two: Configure an IP Address on the mgmt_eth interface, and add a default gateway, then save the configuration. The default gateway must be added in "vrf mng" only if the management interface (mgmt_eth) will be used. If you will use a VLAN interface for management, "vrf mng" is not necessary.

ZXAN# conf t
ZXAN(config)# interface mgmt_eth
ZXAN(config-if)# ip address [IP] [Netmask]
ZXAN(config-if)# exit
ZXAN(config)# ip route vrf mng [IP of the GATEWAY]
ZXAN(config)# exit
ZXAN# write
Write DB OK!

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

Step three:

Create 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

aaa-authorization-template 2001
aaa-authorization-type local

authorization-template 1
bind aaa-authorization-template 2001
local-privilege-level 15

authentication-template 1
bind aaa-authentication-template 2001

user-name smartoltusr
bind authentication-template 1
bind authorization-template 1
password [a strong generated password]

Step four:

Enable telnet

conf t
line telnet server enable

At this stage, your OLT is ready to be interconnected with SmartOLT system.
Open your smartolt.com site, go to Settings -- OLTs -- Add OLT.
Fill in the fields displayed, and click the Save button.

Other settings (If you use SmartOLT, these are configured automatically, no need to configure them manually):

conf t
auto-write everyday 18:00:00
ntp server priority 1
ntp server priority 2
ntp enable

Optional, you can configure an "in-band" IP address on a VLAN interface. This is useful when you want to manage the OLT using the same physical interface that is used for normal traffic of the customers. We do not recommend this scenario because if a loop happens in the ONT, undetected by the ONT/OLT and the uplink port is shutdown by the uplink device as a reaction to the loop, you will lose the IP connectivity with the OLT as well.
conf t
vlan 300
interface vlan300
ip address [IP] [MASK]
ip route [IP OF THE GATEWAY]

Remember! The VLAN must be tagged on the Uplink that will be used:
conf t
interface xgei-1/10/1
switchport mode trunk
switchport vlan 300 tag

Checking the routing table:
ZXAN#show ip forwarding route

In case you want to delete the existing default gateway and add a different one:
ZXAN#conf t
ZXAN(config)#no ip route
ZXAN(config)#ip route [IP OF THE GATEWAY]
