These counters are probably not populated by the end device, this is quite common.

There’s not usually anything you can configure on the device to populate them.

 Good morning! I hope everyone is okay! I have a question about collecting traffic on vlan interfaces. My HPE/3Com devices (7510, 5510, 5520, 4800) show graphs of vlan interfaces but the graph is always empty with no data. On physical interfaces collected normally. Is there any configuration that I need/can do to get the values of the vlan interfaces?

Thanks.

Hello Kleber

Maybe you can make a subinterface, this subinterface have a VLAN , this "alternative method", I prefer using vlans "groups" for service affinity, internal routing, services, internet, data collection, departments, and so on.

The swiths not "see" the traffic vlan like "humans" , the switches only forwarding packets. In swiths the VLAN are "simples, comum memory address", not a "regular interface" with traffic.

For checking the traffic in the interface you have basic two options, using subinterface(easy, cheap and fast) or a netflox (big, expensive and slow).

Subinterface is complication if you need separate each vlan, if you can group VLAN(like us) , enjoy and "have a beer" =)
