Consistency

- Enables automatic, seamless interoperability among all QoS features and parameters across a network topology -LAN, MAN, and WAN

Cisco AutoQoS simplifies and shortens the QoS deployment cycle in these five major aspects of successful QoS deployments:

■ Application Classification: AutoQoS leverages intelligent classification on routers using Cisco network-based application recognition (NBAR) to provide deep and stateful packet inspection. AutoQoS uses Cisco Discovery Protocol (CDP) for voice packets to ensure that the device attached to the LAN is really an IP Phone.

■ Policy Generation: AutoQoS evaluates the network environment and generates an initial policy. AutoQoS automatically determines WAN settings for fragmentation, compression, encapsulation, and Frame Relay-to-ATM Service Interworking (FRF. 8), eliminating the need to understand QoS theory and design practices in various scenarios. You can meet additional or special requirements by modifying the initial policy.

The first release of AutoQoS provides the necessary AutoQoS VoIP feature to automate QoS settings for VoIP deployments. This feature automatically generates interface configurations, policy maps, class maps, and ACLs. AutoQoS VoIP will automatically employ Cisco NBAR to classify voice traffic, and mark the traffic with the appropriate differentiated services code point (DSCP) value. You can instruct AutoQoS VoIP to rely on, or trust, the DSCP markings previously applied to the packets.

■ Configuration: With one command, AutoQoS configures the port to prioritize voice traffic without affecting other network traffic, while still offering the flexibility to adjust QoS settings for unique network requirements.

Not only will AutoQoS automatically detect Cisco IP Phones and enable QoS settings, it will disable the QoS settings when a Cisco IP Phone is relocated or moved to prevent malicious activity.

AutoQoS-generated router and switch configurations are customizable using the standard Cisco IOS CLI.

Systems, Inc. All ngnts m Monitoring & Reporting: AutoQoS provides visibility into the classes of service deployed via system logging and Simple Network Management Protocol (SNMP) traps, with notification of abnormal events (that is, VoIP packet drops).

m Consistency: When deploying QoS configurations using AutoQoS, configurations generated are consistent among router and switch platforms. This level of consistency ensures seamless QoS operation and interoperability within the network.
