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:

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

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is “down” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

3560 specifications

Cisco Systems 3560 is a series of enterprise-class Layer 2 and Layer 3 switches designed to meet the growing demands of modern networks. Launched as part of Cisco's Catalyst series, the 3560 line offers remarkable versatility and reliability for businesses of all sizes.

One of the standout features of the Cisco 3560 switches is their support for advanced Layer 3 routing capabilities. This allows for IPv6 support and enhanced IP routing protocols, including OSPF, EIGRP, and RIP. With built-in static IP routing, the 3560 can perform inter-VLAN routing, thus optimizing network performance by enabling devices on different VLANs to communicate efficiently. This is crucial for modern networks where segmentation is vital for performance and security.

The Cisco 3560 series also excels in Power over Ethernet (PoE) capabilities, allowing network devices to receive power and data over a single cable. This makes it an ideal solution for powering devices such as IP cameras, VoIP phones, and wireless access points without the need for additional electrical outlets. The PoE functionality is particularly beneficial for organizations looking to reduce installation costs and simplify their network infrastructure.

In terms of security, the Cisco 3560 incorporates features such as port security, dynamic MAC address learning, and 802.1X authentication. These features help safeguard the network against unauthorized access and secure sensitive data. Additionally, the switch supports Access Control Lists (ACLs) to filter traffic and improve overall network efficiency.

Management of the Cisco 3560 is facilitated through the Cisco IOS Software, which provides a user-friendly interface for configuration and monitoring. The device can be managed via a command-line interface (CLI) or a web-based GUI, allowing network administrators flexibility in how they interact with the switch. Moreover, Cisco's Smart Install feature simplifies the deployment process for large networks, facilitating plug-and-play configurations.

Another notable characteristic of the Cisco 3560 series is its stackable design, enabling users to connect multiple switches within a single stack to improve scalability. This modular approach allows businesses to expand their network easily as their needs grow, while also providing redundancy.

With a robust set of features tailored for performance, security, and manageability, the Cisco Systems 3560 series continues to be a reliable choice for organizations seeking to enhance their network infrastructure and support the evolving landscape of enterprise networking. It addresses the critical requirements of modern environments and remains a benchmark for performance in enterprise-level switching solutions.
