For a HUAWEI NE40E-X2-M8 switch we noticed that the package count (for the outgoing high capacity multicast packets) could drop again.
After some investigation we saw that these drops are linked with the drops in the broadcast packet count, however not with the same amount (see screenshot).
We believe that this is a device issue.
Does someone know if this problem is fixed?
If so in what FW version can we find this fix?
Currently the device is running:
Huawei Versatile Routing Platform Software
VRP (R) software, Version 8.100 (NE40E V800R007C10SPC100)
Details:
We retrieve the package count from the device (unicast and non unicast for ingoing and outgoing packets) through SNMP.
Based on the package count we calculate the rate (based on the time between two poll cycles).
Based on the speed of the interface we retrieve the package count from the IfTable 32bit (1.3.6.1.2.1.2.2) or from the IfXTable 64bit (1.3.6.1.2.1.31.1.1).
Detail: for the IfXTable the non universal packets is the sum of the multicast and broadcast packets.
We expect that these package counters will do a wrap around.
In code we catch this by evaluating if the previous value is larger than the current value, this way we can still calculate the difference correctly.
At the moment we see that in two concurrent poll cycles the Outgoing Multicast Packets (1.3.6.1.2.1.31.1.1.1.12) the package count can decrease
The ones for which we noticed the package count could drop are (seems to be outgoing package counts):
IfXTable: Outgoing high capacity unicast packets (1.3.6.1.2.1.31.1.1.1.11)
IfXTable: Outgoing broadcast packets (1.3.6.1.2.1.31.1.1.1.5)
IfXTable: Outgoing high capacity multicast packets (1.3.6.1.2.1.31.1.1.1.12)
IfXTable: Outgoing multicast packets (1.3.6.1.2.1.31.1.1.1.4)
IfXTable: Outgoing high capacity broadcast packets (1.3.6.1.2.1.31.1.1.1.13)
Thanks,

Hi @lubna,
I'm not following why a sliding window could let the package count to be dropped.
I would assume that the package is counted either when it is sent out or when it is acknowledged.
Next to that it is also very strange that we see those sudden increases and drops in the graph.
Is there a way that we can validate your claim by checking/trending the another parameter like dropped packages?
