Q.
What is the reporting granularity provided by the Cisco APA module solution?
A.
Cisco APA Network Module provides granular analysis and reporting of application traffic on a
per user basis. Data records generated over a 24-hour period are stored locally on the
resident hard drive and then offloaded to the APADC file system on the management station.
Although the nature of the records and frequency with which they are generated are largely
dependent on the type of information being collected, the device can store data records
collected at one-minute increments for the full 24-hour period. Archival of the reporting data
retrieved daily by the APADC file system is supported for a maximum of 30 days.
Q.
Can the management system report on multiple modules concurrently?
A.
APADC is able to report on traffic patterns from individual modules, without data
consolidation. In order to report on multiple modules, we recommend that customers utilize an
enterprise-class reporting solution, such as Proxy’s PTM solution, or a solution from NetQoS.
Q.
Does the APA module solution provide mechanisms to transport the reports to any
external system?
A.
The APADC application supports the export of reporting results as a JPEG image and CSV
file to an external workstation.
Ordering Information
Q.
Is APA Network Module available to order?
A.
The modules and associated software are currently on the global price list. There are two
forms currently available to order: NME-APA-E2 for the 2800 Series ISR or NME-APA-E3 for
the 3800 Series ISR. Customers that have purchased the NME-APA-E2 or NME-APA-E3 with
the original View Only software are entitled to a free upgrade to the Control software.
Q.
What APA Software is included with the purchase of the network module?
A.
There are two software components for the APA Solution, including the management software
(APA-R3-VO) and the software image (APA-SW-2.0). Both of these software components are
included with the purchase of the module and therefore, are at no cost on the price list.
However, if the customer requires that the module provide both visibility and control, one of
the following software licenses must also be purchased:
●
APA-E2-CC: Control Software License - for 2800 Series
●
APA-E3-CC: Control Software License - for 3800 Series
Q.
How do I order an APA Network Module and associated software?
A.
The modules can be ordered either as part of a configured router solution or as spares for
existing router deployments. Contact your local Cisco sales representative if you require
further assistance.
Service Control Engine Comparison
Q.
How is the Cisco APA Solution different from the Cisco Service Control Engine (SCE)
Solution?
A.
The two solutions share the same technology base but are targeted toward different markets.
The APA Solution is typically suitable for the needs of the distributed enterprise customers
whereas the Cisco SCE Solution is targeted for service providers requiring high-capacity
carrier-grade deployments. As a result, the two solutions differ significantly in terms of scale,
throughput, user/flow limits, reporting requirements, and management. Table 1 summarizes
the differences between the two solutions.
