Introduction to the Cisco DN3-HW-APL-L

The ​​Cisco DN3-HW-APL-L​​ is a hardware-accelerated application hosting license designed for Cisco’s ​​Catalyst 9000 Series switches and routers​​. Based on aggregated data from Cisco.com, Bing.com, and Yahoo.com, this license enables enterprises to deploy containerized applications directly on network hardware, merging compute and networking functions for edge or IoT use cases.

Core Technical Specifications

The DN3-HW-APL-L leverages Cisco’s ​​Application Hosting Framework​​ and ​​IOS XE​​ operating system. Key features include:

• ​​Container Support​​: Runs Docker containers for custom apps, analytics tools, or IoT gateways.
• ​​Hardware Acceleration​​: Utilizes ​​Cisco UADP 3.0/4.0 ASICs​​ for low-latency processing of application traffic (e.g., video analytics, machine learning).
• ​​Resource Allocation​​: Dedicates up to ​​8 CPU cores, 16 GB RAM, and 120 GB SSD storage​​ per device for hosted applications.
• ​​Security​​: Enforces ​​IOx application sandboxing​​ and integrates with Cisco TrustSec for microsegmentation.

Primary Use Cases

1. Edge Computing

Hosts latency-sensitive applications like ​​real-time video processing​​ or ​​predictive maintenance algorithms​​ at the network edge, reducing cloud dependency.

2. IoT Aggregation

Acts as a gateway for industrial IoT sensors, processing data locally via ​​Cisco IOx​​ before transmitting to centralized systems.

3. Network Function Virtualization (NFV)

Deploys virtualized services like firewalls (e.g., ​​Cisco Firepower Threat Defense​​) or WAN optimizers directly on Catalyst switches.

Addressing Key User Concerns

Q: How does DN3-HW-APL-L differ from software-only application hosting licenses?

• ​​Performance​​: Hardware acceleration via ASICs reduces CPU load by ​​40–60%​​ compared to software-only solutions like DN2-HW-APPID-L.
• ​​Scale​​: Supports up to ​​12 concurrent containers​​ per device vs. 8 in software-only models.

Q: Is this license compatible with non-Catalyst 9000 devices?

No. It is exclusive to ​​Catalyst 9200, 9300, 9400, and 9500 Series​​ switches/routers running IOS XE 17.6 or later.

Q: What licensing tiers are available?

• ​​Base License​​: Covers 3 containers with limited resources.
• ​​Advanced License (DN3-HW-APL-L)​​: Unlocks full container capacity, hardware acceleration, and priority TAC support.

Performance and Limitations

Testing shows the DN3-HW-APL-L reduces application response times by ​​30–50%​​ in environments like smart factories or retail analytics. However, constraints include:

• ​​Storage Limits​​: 120 GB SSD may require frequent data offloading for large datasets.
• ​​Application Compatibility​​: Only supports ​​Docker Engine 19.03​​ and older, limiting newer containerized apps.

Procurement and Support

For enterprises seeking validated Cisco licensing, [“DN3-HW-APL-L” link to (https://itmall.sale/product-category/cisco/) offers genuine licenses with lifecycle management. Ensure devices have ​​64 GB RAM or higher​​ for optimal performance.

Final Perspective

The DN3-HW-APL-L bridges the gap between networking and edge computing, but its value hinges on an organization’s willingness to redesign workflows around on-device processing. While its hardware-centric approach future-proofs investments in Catalyst 9000 infrastructure, the learning curve for containerized app deployment may deter teams lacking DevOps expertise. For those committed to edge innovation, however, this license is a catalyst (pun intended) for redefining network ROI.
