Issue
- CRC errors reported in EMS messages. Example:
[node_name: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e0g on node node_name is reporting a high number of observed hardware errors, possibly CRC errors.
- Increasing Error and/or Illegal symbol count observed in
ifstat -a
output of that NIC port, along with CRC errors. Example:
::> system node run -node <node_name> -command ifstat <port_name>
-- interface e0g (123 days, 4 hours, 5 minutes, 6 seconds) --
