Dba-Algorithm Update - H3C S7500E Series Command Reference Manual

intdba: Enables the internal DBA algorithm, which is implemented through the chips of the device.
Description
Use the dba-algorithm enable command to specify that the OLT use the internal or external DBA
algorithm to change the uplink bandwidth of each ONU in real time.
Use the undo dba-algorithm update command to remove the loaded external DBA algorithm file and
restore the use of the internal DBA algorithm.
By default, the OLT uses the internal DBA algorithm to change the uplink bandwidth of each ONU in
real time.
To use the dba-algorithm enable command to enable the external DBA algorithm, use the
dba-algorithm update command to load the specified DBA algorithm file first.
Related commands: dba-algorithm update.
When you use the dba-algorithm update command to upgrade the external DBA algorithm, the
new upgrade file is synchronously loaded onto the backup SRPU, and overwrites the old one (if
any) in the backup SRPU. If the synchronous upgrading operation fails (this may occur when there
is not enough free space on the Flash of the backup SRPU), DBA algorithms on the primary and
backup SRPUs will be different, thus resulting in configuration errors.
To avoid service interruption, enable a new DBA algorithm when no service is in progress.
Examples
# Load an external DBA algorithm file plato3.2.app.
<Sysname> system-view
[Sysname] interface olt 3/0/1
[Sysname-Olt3/0/1] dba-algorithm update Plato3.2.app
# Enable the external DBA algorithm. Enable the external DBA algorithm.
[Sysname-Olt3/0/1] dba-algorithm enable extdba
Warning: Switching DBA may cause some onus of this olt to re-register. Are you
sure?(Y/N)y

dba-algorithm update

Syntax
dba-algorithm update file-url
View
OLT port view
Default Level
2: System level
Parameters
file-url: String of up to 64 characters consisting of device name and the filename of the DBA algorithm.
If no device name is entered, the Flash of the switching and routing process unit (SRPU) will be used.
Moreover, the DBA algorithm file on the backup SRPU cannot be used for the upgrade.
