How to Display IGMP Messages on Huawei MA5600T

When the multicast duplication point is on Huawei MA5600T, how to display the IGMP messages exchanged between the MA5600T and the upper-layer device and between the MA5600T and IGMP users?

EPBA board:

• To display the messages, do as follows:

  huawei#terminal debugging
  % Current terminal debugging is on
  huawei#terminal monitor
  % Current terminal monitor is on
  huawei(config)#debugging igmp all
  

• To cancel the function of displaying the messages, do as follows:

  huawei#undo terminal debugging
  huawei#undo terminal monitor
  huawei#undo debugging igmp

Boards other than the EPBA board:

• The messages can be displayed only based on the index of the IGMP service port. To display the messages, do as follows:

  huawei#terminal debugging
  % Current terminal debugging is on
  huawei#terminal monitor
  % Current terminal monitor is on
  huawei(config)#debugging igmp service-port 68
  

• To cancel the function of displaying the messages, do as follows:

  huawei#undo terminal debugging
  huawei#undo terminal monitor
  huawei#undo debugging igmp

• The preceding methods apply to V800R006C02 and V800R008.
• After the function of displaying IGMP messages is enabled, the device performance may be affected. Therefore, disable this function when it is not used.
