Hi friend.
1. In versions earlier than OLT V800R013C00, you can create a VLANIF interface, set the VLANIF IP address to be the same as the ONT management IP address, create a service port, and then log in to the ONT.
For example:
vlan 100 smart
port vlan 100 0/19 0
interface vlan 100
ip address 192.168.100.2 25
service-port vlan 100 gpon 0/0/0 ont 0 gem 0 multi-serv user-vlan 100
telnet 192.168.100.1
2. In versions later than OLT V800R013C00, you can log in to the ONT using telnet f/s/p/ontid ontip in diagnose mode.
3. If the ONT version is V300R013C00 or later, run the telnet f/s/p/ontid command to log in to the ONT.
For more details about the command, please click:
telnet(ont)
I hope I can help you.
