Features

The Cisco APA Engine is delivered through a combination of purpose-built hardware and specific software that address various traffic management challenges faced by enterprises. The APA Engine performs Layer 7 stateful deep packet inspection and control over network traffic on a per-application, per-user basis. Designed for small data centers and higher education deployments, the solution is able to identify and prioritize about 1,000 applications including ERP applications, voice over IP (VoIP), Web browsing, music downloads, distance learning applications, video streaming, and peer-to-peer (P2P) traffic. It provides users with incremental value over and above existing NBAR technology already available in their routing and switching solutions, and allows the customer to:

•Identify and classify applications and protocols.

•Identify network users and determine their application and network usage patterns (requires integration with existing authentication system).

•Police traffic to guarantee service performance and ensure that traffic usage conforms to the required business model.

•Select a variety of reports from the 100 available templates to represent existing network traffic.

•For higher education users, rapidly create and deliver a variety of unique applications and content-based services, such as prioritized gaming services, which can be offered to the students.

For additional information about features, see the User Guide for the Cisco Application Performance Assurance Engine 1.0.

Known Problems

Table 1 describes known problems in the APA Engine 1.0.

Table 1 Known Problems

Bug ID	Summary	Explanation
CSCso89232	The CAM-APA goes into crash mode when a huge burst of traffic is sent.	If you exceed the supported rate of traffic, the APA Engine Web interface might become unresponsive if, for example, there is a traffic burst of 400 Mbps, which exceeds more than twice the maximum supported sustained rate of 200 Mbps. The APA Engine resets itself and engages the hardware bypass mode. Workaround: Keep the APA Engine running below the maximum supported sustained rate of 200 Mbps. You might need to reconnect to the APA Engine with APADC and configure the Full Functionality mode.
CSCso89319	Traffic is dropped when the system mode is switched to Transparent mode.	When you change the system mode to Transparent mode, traffic is dropped for several seconds. Workaround: Schedule the switch to Transparent mode to occur at a non-peak time. The system mode does not need to be changed frequently.
CSCso64557	The APA is unable to generate Top IP Protocol graph for a particular class.	The Top IP Protocol graph might be empty for a particular class. Workaround: None. You can generate a similar graph by not selecting the class in the Class To View field.
CSCsq18241	Added APADC admin user names cannot be edited if the number of Admin user is less than three.	You cannot edit the names of Admin users if there are less than three users with the IT Manager role. Workaround: Add additional Admin users with the IT Manager role until you have at least three such users, and then you can modify the names as needed.
CSCsq27914	Applying the system mode from APADC might not remove the hardware bypass condition from the APA Engine.	The APA Engine might remain in Transparent mode and cannot be put in Report Only mode. Workaround: Follow these steps: 1. Using the APADC, specify the Full Functionality mode for the APA Engine. 2. Using the APADC, apply the desired system mode.
