Example

To query the DBA modes of all the GPON ports on board 0/3, do as follows:

huawei#display gpon port dba bandwidth-assignment-mode             
{ frameid<U><0,0>}:0
{ all<K>|slotid<U><0,22>}:3                   
{ all<K>|portid<U><0,15> }:all                                                                                                         
  Command:
          display gpon port dba bandwidth-assignment-mode 0 3 all

System Response

• The system displays the queried result when the command runs successfully.
• The following table describes the parameters in response to this command.

  Parameter	Description
  F/S/P	Indicates the shelf ID, slot ID, and port ID.
  Bandwidth-assignment-mode	Indicates the DBA mode. It can be default, min-loop-delay, max-bandwidth-usage, or manual. default: In this mode, the DBA mode configured in global config mode is used. min-loop-delay: In this mode, the bandwidth is issued in single frame issue mode and therefore the delay is short. This mode must be used for time division multiplexing (TDM) services. max-bandwidth-usage: In this mode, the bandwidth is issued in DBA calculation period. The DBA calculation period is fixed to eight frames. This mode is used for services that are not sensitive to delay. manual: In this mode, you can manually set the DBA mode and DBA parameters. This mode is used when the min-loop-delay mode and max-bandwidth-usage mode cannot meet customers' requirements.
