Hello,
I have a switch:
- HUAWEI S6720-32C-PWH-SI
- Version 5.170 (S6720 V200R011C10SPC600)
I obtain the following logs when we are doing backups:
Dec 1 2020 16:19:23+01:00 SWHW-SEU1 %IFPDT/4/PKT_OUTDISCARD_NL(l)[5]:Interface output discard restored to the log threshold. (Interface=MultiGE0/0/23, Statistics=38285, LogThreshold=300, LogInterval=300(s),PortQueueNumber=0, PortQueuePassed=389166347, PortQueueDropped=38285, PortQueueNumber=1, PortQueuePassed=9433, PortQueueDropped=0,PortQueueNumber=2, PortQueuePassed=0, PortQueueDropped=0, PortQueueNumber=3, PortQueuePassed=0, PortQueueDropped=0,PortQueueNumber=4, PortQueuePassed=164, PortQueueDropped=0, PortQueueNumber=5, PortQueuePassed=0, PortQueueDropped=0,PortQueueNumber=6, PortQueuePassed=1281052, PortQueueDropped=0, PortQueueNumber=7, PortQueuePassed=830265, PortQueueDropped=0)

The log shows that packet loss occurs on g0/0/23 and g0/0/24. Can I do something to avoid those discards? Where is the threshold? Do I must enable flow control?
Thanks.
