View
FTTH view
Default Level
2: System level
Parameters
oui-value: OUI (Organizationally Unique Identifier) of the ONU.
version-value: OAM (Operation, Administration and Maintenance) version number of the ONU.
&<1-9>: Indicates that you can specify up to 9 OUI values/OAM version numbers.
slot-number: Number of the slot where an OLT port resides, taking the value of 1.
Description
Use the epon-parameter ouilist command to configure the OUI and extended OAM version number of the ONU.
Use the undo epon-parameter ouilist command to cancel the configuration.
By default, the OUI and extended OAM version number are 111111 and 1 respectively. After this configuration, an H3C ONU attached to an OLT goes online after being bound with the specified ONU port (The OUI and extended OAM version number for an H3C ONU are 111111 and 1 respectively).
Note the following:
l Entries with the same OUIs and extended OAM version numbers cannot be configured at the same time.
l When the OUI and extended OAM version number list changes (when a list is configured or canceled), all the ONUs will reregister.
Related commands: display epon-parameter.
Examples
# Configure the OUI and extended OAM version number of the ONU.

Description
Use the oam-discovery-timeout command to configure the timeout time of extended OAM messages exchanged between an OLT and its ONU during an extended OAM discovery process.
Use the undo oam-discovery-timeout command to restore the default value of the extended OAM discovery timeout time.
Related commands: display epon-parameter
l You are recommended to use the default value of this parameter.
l If an OLT stays down after being bundled with an ONU port, you can change the extended OAM discovery timeout time to a larger value.
Examples
# Set the timeout time of extended OAM messages exchanged between the OLT and the ONU to 6 seconds.
