AVC Features in Cisco IOS Releases
Table B-1 AVC Feature History for Cisco IOS Releases
|
|
---|---|
Cisco IOS 15.5(3)T |
|
Added support for Cisco 5915, 5921, 5930, 5940 routers For more information, see: AVC Supported Platforms |
|
Cisco IOS 15.5(2)T |
|
Option to specify the cache timeout (exporting interval) in seconds. At this interval, the cached NetFlow records are exported. For more information, see: ezPM Configuration Options |
|
Cisco IOS 15.5(1)T |
|
The Application Performance profile is an improved form of the existing Application Experience profile. Application Experience remains available to support legacy configurations, but it is recommended to use the Application Performance profile for new configurations. For more information, see: Application Performance Profile |
|
Due to an improvement in NBAR (class-hierarchy feature), URL and Media traffic monitors can more accurately identify HTTP traffic. For more information, see: Easy Performance Monitor (ezPM) |
|
NBAR provides two levels of application recognition: fine-grain and coarse-grain. Fine-grain mode provides NBAR's full application recognition capabilities. Coarse-grain mode offers a performance advantage by minimizing deep packet inspection, and can be used in scenarios where the full power of fine-grain classification is not required. For more information, see: NBAR2 Fine-grain and Coarse-grain Modes |
|
Cisco IOS 15.4(3)T |
|
The Application Statistics profile collects application statistics on all IPv4 and IPv6 traffic. It is a simpler profile than the Application Experience profile introduced in an earlier release. A new cache-type parameter enables specifying the type of cache for a monitor. For more information, see: Easy Performance Monitor (ezPM) |
|
Cisco IOS 15.4(1)T |
|
The convergence of AVC architecture brings together the strongest AVC features from IOS and IOS XE platforms, providing powerful features and greater standardization of configuration tasks across different Cisco platforms. Metrics, such as ART, HTTP, and QoS metrics, that were available in earlier releases can now be configured in the same way as on Cisco IOS XE platforms. Additional metrics are also newly available for Cisco IOS. |
|
The Metric Mediation Agent (MMA) introduces an enhancement to Cisco AVC infrastructure, enabling addition of stateful and derived parameters with dynamic registration. The MMA provides aggregation of connections, history, and alarms from the route processor. The aggregated data is exported at a lower speed than the data path export. For more information about the MMA, see: |
|
This Cisco AVC release provides new monitors for collecting metrics related to Quality of Service (QoS) policy. Monitors can indicate:
For more information, see: |
|
Easy Performance Monitor “express” method of provisioning monitors. Easy perf-mon provides “profiles” that represent typical deployment scenarios. After a user selects a profile and specifies a small number of parameters, Easy perf-mon provides the remaining provisioning details. This release provides one profile, which includes five different traffic monitors. Future releases will provide additional options. For more information, see: |
|
The export-spreading feature spreads out the export of records from the monitor cache over a time interval, to improve collector performance. For more information, see: |
|
Features Available Prior to Cisco IOS 15.4(1)T |
|
Unifies the technologies of several reporting/control solutions. AVC technologies include the configuration mechanism, metrics, and reports of such components as TCP performance, and so on. |
|
For an overview of the metrics collected by Cisco routers, both for Cisco IOS and for Cisco IOS XE, see: |
|
For information about using these metrics, see Configuring AVC to Monitor MACE Metrics. |
|
AVC includes several TCP performance measurements for traffic performance reporting. |
|
The Cisco Prime Infrastructure management and reporting system is an integral part of the Cisco AVC solution and provides extensive management and reporting features, including provisioning the system, storing exported data, and generating reports. |
AVC Features in Cisco IOS XE Releases
Table B-2 AVC Feature History for Cisco IOS XE Releases
|
|
---|---|
Cisco IOS XE 3.15S |
|
A router operating in layer 2 transparent mode (local switching) bridges two interfaces, transparently forwarding packets directly from one interface to the other, without any other routing functionality. AVC can operate on a device configured in this mode, providing full AVC functionality on the bridged traffic. For more information, see: AVC Compatibility with Layer 2 Transparent Mode |
|
Option to specify the cache timeout (exporting interval) in seconds. At this interval, the cached NetFlow records are exported. For more information, see: ezPM Configuration Options |
|
Cisco IOS XE 3.14S |
|
The Application Performance profile is an improved form of the existing Application Experience profile. Application Experience remains available to support legacy configurations, but it is recommended to use the Application Performance profile for new configurations. For more information, see: Application Performance Profile |
|
Due to an improvement in NBAR (class-hierarchy feature), URL and Media traffic monitors can more accurately identify HTTP traffic. For more information, see: Easy Performance Monitor (ezPM) |
|
Multiple policies can be configured simultaneously on an interface, enabling additional flexibility in metrics collection. For more information, see: Configuring Multiple Policies on an Interface |
|
NBAR provides two levels of application recognition: fine-grain and coarse-grain. Fine-grain mode provides NBAR's full application recognition capabilities. Coarse-grain mode offers a performance advantage by minimizing deep packet inspection, and can be used in scenarios where the full power of fine-grain classification is not required. For more information, see: NBAR2 Fine-grain and Coarse-grain Modes |
|
Cisco IOS XE 3.13S |
|

|
Cisco IOS XE 3.12S |
|
