About User Logins
You can use one of the following methods to log in to an Optical Line Terminal (OLT):
-
Console port: You can log in to an OLT directly through the console port.
-
Telnet: You can configure an OLT as a Telnet server. By default, the Telnet Server feature is enabled on an OLT but without an IP address, the client OLT cannot log in to the server OLT. To set up a login through Telnet, configure the IP address on the OLT through the console port. After the IP address is configured on the OLT Telnet server, you can configure other OLTs as Telnet clients.
-
SSH: You can configure an OLT as an SSH server, but not an SSH client. The SSH Server feature is disabled on the OLT by default. Log in to the OLT through the console port to enable the SSH Server feature and configure the SSH settings.
To set up SSH login on an OLT, perform the following steps: -
Open SSH.
-
Configure the default key.
-
Activate the default key.
Note
The key file and configuration are saved on the flash drive and are not decompiled.
-
-
Network Management Software (NMS): The OLT supports login management through the NMS software.
The SNMP server function is required for the operation of the NMS. The SNMP server function is not supported on certain OLTs. For certain OLTs, the SNMP server is enabled by default after the corresponding device is switched on; the SNMP server cannot be disabled.
By default, the SNMP server has the following communities configured:
-
Private community with read-write authority.
-
Public community with read-only authority.
