How Do I Check Whether a NIC Supports the FDIR Function?

Run the following command to check whether the NIC supports FDIR:

1

ethtool -k NIC name |grep filters

• If the output contains ntuple-filters but does not contain [fixed], the NIC supports FDIR.

  

  

• If the output is ntuple-filters:off[fixed] or empty, the NIC does not support FDIR.
