# Troubleshooting Network Configuration Errors

Proper network configuration is critical to the reliable operation of Commvault Grid nodes.

Common network-related issues and their resolutions are described in the following topics:

- Verifying Active-Backup Bonding Configuration

- Verifying LACP Bonding Configuration

- Troubleshooting Errors When Network Interfaces Appear Offline

- Troubleshooting Errors When You Are Unable to Ping the Gateway or Other Nodes

Note

Cisco Fabric Extenders (FEX) are not suitable for storage-based solutions. Connecting Commvault Grid nodes to a Cisco FEX is not recommended, as it can lead to stability and performance issues.
