Commvault CVP
**Commvault CVP** uses port 8400 to enable unified management of data backup, recovery, archiving, and compliance across cloud and on-premises environments. It facilitates secure and efficient data handling operations as part of the **Commvault platform**, supporting a wide range of enterprise data management tasks. Both TCP and UDP protocols are supported to ensure flexible connectivity for client-server communications, agent interactions, and administrative control..
Port 8400 is designated for Commvault CVP (Commvault Unified Data Management) component’s communication within the Commvault architecture. This port acts as a critical hub for coordinating data movement, client management, and administrative commands, facilitating seamless interaction between media agents, clients, and the CommServe server. Communication over port 8400 is essential for managing backup and recovery jobs, scheduling, reporting, and licensing tasks.
Technically, Commvault's distributed architecture leverages this port primarily for its internal protocol workflows as well as for API requests to orchestrate data protection policies. The server accepts connections from various agents deployed across environments, enabling real-time control and monitoring of backup jobs, restores, and data migration activities. Port 8400 supports both TCP and UDP, with TCP typically used for reliable transmission of commands and data streams, while UDP may be utilized for lightweight status monitoring and discovery operations.
Furthermore, port 8400 integrates with the broader enterprise networking stack, operating within secure network zones or across hybrid cloud deployments. Administrators usually configure firewall exceptions to allow traffic on this port between trusted components. The port may also interface with storage backends, tape libraries, and cloud APIs under the management workflows ensured by Commvault.
