Ifstat NOPROTO counter increasing on all VLAN ports

Hello,

We are running ONTAP 9.8P10.

All VLAN ports are showing an increasing number of the noproto counter in the ifstat output.

I have already checker this: https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/Troubleshooting_Ethernet_Network_Ports_in_ONTAP_using_ifstat

It says:

- Noproto

  - If a port receives a packet tagged with a VLAN ID that does not exist, the packet will be dropped and this counter will be incremented.

"Does not exist" meaning that the VLAN does not show up under "vlan show -port <affected_port>"

Networking side checked and all the VLANs on the switch ports are created on the NetApp side.

Any ideas?

We'll get some packet traces to check also.

Thanks,

Pedro
