Network switch license EXTREME 16x10GbE Ports On Demand for VDX6940-64S (AC/DC models)

On-demand license for EXTREME VDX6940-64S series that enables 16 additional 10GbE ports on AC and DC power variants. This license activates extra 10 Gigabit Ethernet capacity on supported VDX6940-64S systems without requiring physical hardware changes, allowing administrators to scale port density quickly and cost-effectively. The license applies to both AC and DC power models and is intended for use in data center spine/leaf fabrics and enterprise aggregation environments where rapid port expansion is needed.

Advantages

The license provides a non-disruptive way to increase available 10GbE ports, avoiding the time and expense of installing new line cards or chassis upgrades. Activation is software-driven and preserves the existing physical installation, minimizing deployment complexity. It supports flexible capacity planning by enabling temporary or permanent port expansions and allows network operators to match port count to traffic demands without procuring additional hardware.

Suitable for

• Data center leaf or spine switches requiring additional 10GbE ports
• Enterprise aggregation switches where port capacity must be scaled quickly
• Temporary capacity increases for seasonal or project-based traffic spikes
• Consolidation scenarios where physical re-cabling or hardware changes are impractical

Key specifications

• License type: On-demand software license that enables additional ports
• Additional ports enabled: 16 x 10 Gigabit Ethernet
• Compatible models: EXTREME VDX6940-64S series (AC and DC power variants)
• Activation method: Software activation on the switch platform without hardware modifications
• Use case: Port capacity scaling for aggregation and data center deployments

How to use

Obtain the license key from EXTREME or an authorized reseller and follow the vendor-provided activation procedure for the VDX6940-64S platform. Use the switch management interface or command line to apply the license and verify that the additional 16 x 10GbE ports are reported as available. No physical installation is required; ports become usable after successful activation and any necessary interface configuration. Ensure the switch software version meets the minimum requirements for license application before proceeding.

Usage recommendations

Before activation, confirm current system capacity, power budget, and cooling margins to ensure the platform supports the increased active port count. Plan any additional VLANs, routing, or traffic engineering changes to integrate the new ports into existing network topologies. For temporary deployments, track license expiration or deactivation procedures. Contact EXTREME support for compatibility checks or if multiple license increments are required to reach desired capacity.
