Description
Use the update onu onu-type command to update ONUs by type.
Use the undo update onu onu-type command to cancel ONU update configuration by type.
Note that this is a configuration command. It takes effect only on the specified type of ONUs on which
no update command is configured under the ONU port.
If the ONU is online and matches the specified update file, the ONU is updated directly.
If the ONU is online but does not match the update file, the update will fail.
If the ONU is not online (because the ONU port is not bound with any ONU or the extended OAM
connection fails on the bound ONU), the update process will not start until the ONU goes online.
Updating ONUs by type is recommended because it is efficient and easy-to-use.
After the update command is issued, the OLT will wait 15 to 20 seconds before executing the
command. This allows for batch updating and saves system resources.
The update configuration performed in port view takes precedence over that in FTTH view. For
example, assume the ONU corresponding to ONU port ONU 3/0/1:1 is of type A. If you configure
the update file for type A ONUs as 1.app in FTTH view and configure the update file as 2.app in
ONU 3/0/1:1 port view, 2.app will be used to update the ONU.
Any power failure during the ONU software upgrade may cause update failure.
Once the update file is transferred to the ONU, the ONU restarts automatically to complete the
update.
An OLT can update up to 64 types of ONUs at the same time. That is, update files can be
specified for up to 64 types of ONUs at the same time through the command line for updating
ONUs by type.
The update onu onu-type command is a configuration command, that is, after the update onu
onu-type command is executed, it will be saved in the configuration file of the device. If the ONU
port corresponding to an ONU that goes online is created before the update command is used, the
ONU will be updated directly (if it matches the update files). Otherwise, the ONU will not be
updated. To update only the current ONUs online but not the offline ONUs or subsequently
registered ONUs, execute the update onu onu-type command, and use the undo update onu
onu-type command after you make sure that all online ONUs have been updated.
Examples
# Update all the ET704-A-L ONUs under the switch.
<Sysname> system-view
[Sysname] ftth
[Sysname-ftth] update onu onu-type et704-a-l filename file.app
After the command is executed, the OLT starts updating all the ET704-A-L ONUs on which no update
command is configured under the ONU port.
