Parameters
onu-type
: ONU type, a string of 1 to 16 case-insensitive characters, such as ET704-A and ET704-A-L.
file-url
: Update file name, a string of 1 to 64 characters composed of the device name and the ONU
update file name. If no device name is specified, it is the name of the Flash of the SRPU. The files in the
salve SRPU cannot be used for the update.
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.
