Huawei Switch S6700 Vlan traffic

Please add traffic collection from L2 vlans from Huawei 6700 switch.
So far, I have been doing this on Cacti through
“index” => “.”,
“bytesIn” => “.”,
For the above to work, it is also necessary to activate the switch in vlan xxxx → statistics enable on the switch.

Alternatively, I am asking for some information on how I can do it myself. I’m not interested in individual OIDs, but in vlan detection.
Thank you in advance
