# Setting Up Networking for Commvault Grid Nodes

Network configuration is the first phase of deploying Commvault Grid nodes. During this phase, you configure the network interfaces that will be used for:

- Data protection traffic
- Storage pool communication
- Optional management communication
- VLAN-based traffic segmentation
- Network redundancy and failover

The deployment workflow and configuration screens vary depending on the network topology selected for your environment. Before proceeding, determine the network topology that best meets your operational, resiliency, and segmentation requirements.

Important

Before configuring Commvault Grid nodes, review and select the appropriate network topology.

Cisco Fabric Extenders (FEX) are not recommended for Commvault Grid deployments. Connecting Commvault Grid nodes through a Cisco FEX can introduce performance and stability issues.

## Before You Begin

Verify that the following tasks have been completed:

- DNS records have been created and validated.
- Network switches have been configured.
- The required VLANs have been created (if applicable).
- IP addresses have been allocated for all nodes.
- Commvault Grid software version validation has been completed.
- Hardware readiness checks have been completed.

## Choose a Deployment Method

Select the deployment procedure that matches the network topology used in your environment.

Topology | Recommended Use Case
--- | ---
Basic Deployment | Small deployments, lab environments, and non-production environments
Bonding (Active-Backup or LACP) | Production environments requiring network redundancy
Basic Deployment with Management Network | Isolated backup networks that require separate management communication
Bonding with Management Network | Production environments requiring both network redundancy and management isolation
Tagged VLAN | Environments that use multiple backup VLANs or segmented backup networks
Tagged VLAN with Management Network | Segmented backup networks that require separate management communication
Tagged VLAN with Bonding | Enterprise environments requiring both VLAN segmentation and network redundancy
Tagged VLAN with Bonding and Management Network | Large-scale enterprise deployments requiring segmentation, redundancy, and management isolation
