The software of the Nokia ONTs can be updated automatically via the ISAM. We describe here the necessary configuration on the CLI (without AMS) so that the ONTs can all be kept on the same software version.
Upload ONT image to ISAM
First, the ONT image must be copied to the ISAM. We use TFTP for this, which must first be activated on the ISAM.
configure system security filetransfer protocol tftp
The desired release can then be copied to the /pub/OntSw/Download/ folder on the ISAM using a TFTP client (e.g. Tftpd64). In this example the ONT software image FE45655BOCK71 is uploaded for the ONT model G-010G-Q:
Configuration of automatic ONT upgrade
The software upgrade of the ONTs is set up so that it happens automatically if an ONT does not have the defined software release. This can trigger both a downgrade and an upgrade and is defined with the following commands on the ISAM (again for the G-010G-Q model).
configure equipment ont sw-ctrl 1 hw-version 3FE47211EB* plnd-sw-version 3FE45655BOCK71 plnd-sw-ver-conf 3FE45655BOCK71 sw-dwload-ver 3FE45655BOCK71
Note: The ONT software must first be copied to the ISAM before this command can be executed.
In order for the ONTs to download and install the defined software, it must be defined for each ONT interface.
configure equipment ont interface 1/1/1/1/1 sw-ver-pland auto sw-dnload-version auto
The following two commands can be used to check the status of the upgrade for the ONTs:
show equipment ont sw-download show equipment ont interface
The ONT is automatically restarted after the upgrade.
➡️ To ensure that the ONT continues to function in the event of a software mismatch, the following command must be configured on the ISAM.
configure system pon-ont sw-ver-mis-block disable
