Applies to

  • NetApp StorageGRID 11.3
  • NetApp StorageGRID Appliance SG6000

Issue

  • The frame error counter (NRER) on StorageGRID network interface is continually increasing.
  • Ifconfig output on the interface shows both receive (Rx) error and frame errors:

root@host:~ # ifconfig hic2
hic2:flags=6211<up,broadcast,running,...>  mtu 1500
 ether xx:yy:zz:xx:yy:xx  txqueuelen 1000  (Ethernet)
  RX packets 5557116789  bytes 2372433298793 (2.1 TiB)
  RX errors 761369 dropped 0  overruns 0  frame 761369
  TX packets 7244109719  bytes 2585709354046 (2.3 TiB)
  TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

  • And ethtool output shows that rx_in_range_len_errors_phy counter has the same value (or same order of magnitude):

root@host:~#  ethtool -S hic2 | grep -i error
rx_crc_errors_phy: 0
rx_in_range_len_errors_phy: 761404
tx_errors_phy: 0
tx_pause_storm_error_events: 0
