Chapter 5 WAVE Interface Modules

Network Adapter Cabling Requirements

Some switches support automatic medium-dependent interface crossover (MDIX). You can configure MDIX by using the mdix auto global configuration switch command. If your switch supports MDIX, you do not need to follow these cabling rules because MDIX automatically adjusts transmit and receive pairs when an incorrect cable type (crossover or straight-through) is installed on a 10/100 Fast Ethernet port. However, when you configure MDIX, you must also configure the port to use autosense (not manual selection of speed/duplex).

Caution If you are connecting to Fast Ethernet ports on both the LAN and the WAN sides of the WAVE inline appliance, you must consider the types of devices that are being connected, and you must use the correct cables. You must follow these cabling instructions for the inline network adapter to work properly. (See Table 5-6. For illustrations and examples, see the “Installation Scenarios and Cabling Examples for Fast Ethernet Connections” section on page 5-10.)

To connect the inline network adapter using the correct cables for Fast Ethernet connections, follow these steps:

Step 1 Determine the type of cable that you would use for a direct connection between your two end devices (without a WAVE inline network appliance connected between them) by using the following standard cabling rules:

When you are directly connecting two network devices that are similar, such as two switches, use a crossover cable.

When you are directly connecting two network devices that are different, such as a switch and router, use a straight-through cable.

Note Because the inline network adapter has an internal crossover connection that becomes active when the InlineGroup interface is placed in mechanical bypass mode, you must decide which cable you would use to connect the two network devices directly, and then you must install the other cable type (on one side, usually the WAN side of the inline appliance) instead.

Table 5-6shows the cable requirements for WAVE and non-WAVE connections when you are using Fast Ethernet end to end.

694, WAVE594K9 specifications

Cisco Systems WAVE594K9 is a state-of-the-art application delivery controller (ADC) that is designed to optimize the performance and availability of applications across a wide area network. As part of Cisco’s advanced networking solutions, the WAVE594K9 effectively enhances application delivery, ensuring a seamless user experience even under heavy traffic conditions.

One of the primary features of the WAVE594K9 is its ability to provide comprehensive traffic management. This device intelligently load balances incoming requests and distributes them across multiple servers. By optimizing resource allocation, it minimizes response times and maximizes throughput, which is particularly beneficial for organizations dealing with fluctuating traffic patterns.

The WAVE594K9 also excels in application acceleration. This is achieved through various optimization techniques, including compression and caching. By reducing the size of transmitted data and storing frequently accessed content closer to users, the WAVE594K9 significantly speeds up application delivery. As a result, businesses can ensure that their users experience minimal latency, even when accessing resource-intensive applications.

Security is another key characteristic of the WAVE594K9. It integrates advanced security features, such as application layer firewalls, SSL offload capabilities, and DDoS protection. These built-in security measures not only safeguard sensitive data but also improve performance by offloading decryption tasks from application servers, allowing them to focus on processing actual requests.

Moreover, the WAVE594K9 is equipped with robust monitoring and reporting tools. Administrators can gain real-time insights into application performance, user activity, and traffic patterns. This level of visibility enables proactive management and troubleshooting, which helps in identifying and resolving potential issues before they impact end-users.

In terms of scalability, the WAVE594K9 is designed to grow with an organization’s needs. It can easily be integrated into existing IT infrastructures and expanded as traffic demands increase. This flexibility makes it an ideal solution for businesses of all sizes, from small enterprises to large corporations.

To summarize, the Cisco Systems WAVE594K9 is a powerful ADC that enhances application delivery through intelligent traffic management, application acceleration, built-in security features, and comprehensive monitoring tools. Its ability to scale effectively makes it a strategic investment for ensuring optimal application performance in today’s dynamic IT environments.
