Obtaining Technical Assistance

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

EMEA: +32 2 704 55 55

USA: 1 800 553-2447

DFC3A, DFC3BXL, DFC3B specifications

Cisco Systems, a leader in networking and communication technology, has developed various products to enhance the performance and efficiency of network systems. Among these products, the Distributed Forwarding Card series stands out, particularly the DFC3BXL, DFC3B, and DFC3A. These cards are designed to provide advanced data forwarding capabilities in high-performance networking environments.

The DFC3BXL is a high-end forwarding card that supports advanced hardware-based packet forwarding, ensuring minimal latency and maximum throughput. With a forwarding capacity of up to 40 Gbps, it is well-suited for large enterprise networks that require fast and reliable data processing. One of its significant features includes support for load balancing across multiple ports, enhancing the network's efficiency and resilience.

The DFC3B, on the other hand, offers a balanced combination of performance and cost. With a forwarding capacity of 32 Gbps, it is ideal for medium-sized networks looking for reliable performance without the higher price tag associated with the DFC3BXL. It also supports advanced Quality of Service (QoS) features, enabling administrators to prioritize critical applications and manage bandwidth effectively.

Lastly, the DFC3A serves as an entry-level option for organizations that need basic forwarding capabilities. With a maximum forwarding capacity of 16 Gbps, it is suitable for smaller networks or branch offices. Despite being an entry-level card, it still offers essential features such as support for standard networking protocols and basic QoS capabilities.

All three cards leverage Cisco's robust architecture, providing high reliability and fault tolerance. They are designed to be easily integrated into existing Cisco devices, allowing for seamless upgrades and expansions. Additionally, these forwarding cards feature built-in telemetry and diagnostics tools, enabling network administrators to monitor performance in real-time and quickly address potential issues.

Technologically, all three cards utilize Cisco’s innovative ASICs (Application-Specific Integrated Circuits), designed to optimize packet processing. This ensures that packet forwarding remains efficient even under heavy network load conditions.

In summary, Cisco's DFC3BXL, DFC3B, and DFC3A Distributed Forwarding Cards cater to varying needs within enterprise networks, from high-end performance to basic functionality. Their advanced features, coupled with Cisco's proven reliability, make them an excellent choice for organizations looking to enhance their network infrastructure.
