Applies to
NetApp StorageGRID Appliances
Issue
- StorageGRID reports Alert Node network reception frame error
- From Support > Grid Topology > SSM > Resources, alarm reported NRER and/ or NTER alarms.
Examples:
- Ensure to verify and follow: Frame errors incrementing against StorageGRID node after network maintenance
-
In Overview page, scroll down to the network Receive statistic table.
- Find out the affected NIC by matching the amount of Frames of each NIC with Receive Errors at the bottom of the table.
- Troubleshoot via SSH:
- Login command line of the affected node as user root:
- Review statistic of all NICs:
ifconfig
- Review statistic of a specific NIC:
ifconfig <nic>
- Example:
- Review statistic of all NICs:
- Login command line of the affected node as user root:

- Find out physical MAC of member NICs in a bound:
cat /proc/net/bonding/<bound_name>
- Review NIC settings:
ethtool <nic>
- Review NIC SFP information:
ethtool -m <nic>
- Review detail statistic of a specific NIC:
