# Deploy Commvault Grid Using Bonded VLAN Topology

Commvault Grid nodes can be deployed in environments that use tagged virtual LANs (VLANs) together with bonded network interfaces.

In this topology:

- Bonded interfaces are used for data protection traffic across multiple tagged VLANs.
- Each VLAN is assigned its own IP address.
- One VLAN must remain routable and is used for CommServe registration and data protection operations.
- Additional VLANs can be configured as non-routable networks and are used exclusively for data protection traffic.
- Bonded interfaces are also used for storage pool communication and replication between Commvault Grid nodes.

The following bonding modes are supported:

- Mode 1 (Active-Backup), which provides fault tolerance through a standby interface.
- Mode 4 (802.3ad), also known as Link Aggregation Control Protocol (LACP), which provides network redundancy and load distribution.

This deployment method is recommended for production environments that require both network segmentation and network resiliency.

Use this procedure to deploy the Commvault Grid software using the Hyperscale ISO 3.2312 or higher version.

Note

- During the setup process, ensure that the following passwords do not contain the special characters `'`, `"`, `/`, `~`, or `\`:

  - Root password
  - Restricted shell user (`cvbackupadmin`) password
  - CommServe connection password

- When deployment is complete:

  - Password-based root access is disabled.
  - Firewall protection is enabled.
  - Ransomware protection is enabled automatically.

## Before You Begin

- If you plan to connect to an existing CommServe server, gather the following information before you begin:

  - The fully qualified domain name (FQDN) of the CommServe server.
  - The credentials of an administrative user.
  - Confirmation that TCP ports 8400 and 443 are open between the nodes and the CommServe server.

- The Managed Service Provider (MSP) administrator or the tenant administrator performing the installation must obtain the authorization code.

  For instructions on activating the authorization code, see User Administration and Security.

- Verify the requirements needed to set up the Bonded VLAN Topology in your environment.

  Tip

  Keep the network names, VLAN IDs, and IP addresses listed in the Network Requirements section of Bonded VLAN Topology handy before you start the configuration. This will help you accurately enter the required values during deployment.

- Verify that the required VLANs have been created on the network switches and that VLAN tagging has been configured correctly.

- Verify that at least one VLAN is routable and can communicate with the CommServe server.

- Verify that all additional VLANs required for data protection traffic are available and accessible from all nodes.

- Verify that the network switches are configured for the selected bonding mode.

  - For Active-Backup deployments, verify that the required interfaces are connected and operational.
  - For LACP deployments, verify that the required port-channels have been created for both the data protection and storage pool networks.

- Verify that the same bonding mode will be used for both the data protection and storage pool interfaces.

- Verify that all nodes can communicate with each other on the storage pool network.
