Packet loss

Hello dear,

Check it:

1 - Query packet loss on an upstream port. Run the display port statistics command to query packet loss of the board providing the upstream port.

huawei(config-if-eth-0/2)#display port statistics


2 - Query packet loss on a PON port. Run the display statistics gmac command to query packet loss on the PON MAC chip, that is, the PON board.

huawei(diagnose)%%display statistics gmac 0/1 0


3- To query the performance statistics for ONT 0 that is connected to GPON port 0/3/0 in privilege mode, do as follows:

https://support.huawei.com/hedex/hdx.do?docid=EDOC1100047618&id=EN-US_TASK_0140687393&lang=en


huawei#display statistics ont 0/3 0 0
-------------------------------------------------------
Upstream frames : 0
Upstream bytes : 0
Upstream discarded frames : 0
Downstream frames : 123
Downstream bytes : 123
Downstream discarded frames : 23422
-------------------------------------------------------

Hope this help you!

Hello,

1.You can try the following command to check if MC_ING_MC_UNMC_CAR_DROP (unknown multicast ), MC_ING_MC_UUC_CAR_DROP (unknown unicast), or MC_ING_MC_BC_CAR_DROP (broadcast) is increasing:
(diagnose)%%display statistics ptype 0/slotid //wait 5 second

(diagnose)%%display statistics ptype 0/slotid //wait 5 second

(diagnose)%%display statistics ptype 0/slotid


2. As the unknown multicast suppression is not set (although broad multicast and unknown unicast suppression is set), you can also try to set it:

Format
ETH mode, MPU mode :

traffic-suppress { portid | all } { broadcast | multicast | unicast } value value

undo traffic-suppress { portid | all } { broadcast | multicast | unicast }

Global config mode:

traffic-suppress { frameid/slotid | all } { broadcast | multicast | unicast } value value

undo traffic-suppress { frameid/slotid | all } { broadcast | multicast | unicast }


such as:
(config)#traffic-suppress 0/1 multicast value 7


Hope this help you!
Thanks
