Re: Voip vs Enterprise : 12.2T vs 12.3T

Joe , plz ignore my ignorance (if any found).

what i got is cisco introduced first AutoQos-Voip in 12.2T . This does not
have "*any*" discovery phase and straight away deploys MQC class-maps and
policy maps for voice-related traffic.

Configuring the AutoQoS  VoIP Feature on a High-Speed Serial Interface
Example

In this example, the AutoQoS  VoIP feature is configured on the high-speed
serial interface s1/2.

Router> *enable*

Router# *configure terminal*

Router(config)# *interface s1/2 *

Router(config-if)# *bandwidth 1540 *

Router(config-if)# *auto qos voip *

Router(config-if)# *exit *

Configuring the AutoQoS  VoIP Feature on a Low-Speed Serial Interface
Example

In this example, the AutoQoS  VoIP feature is configured on the low-speed
serial interface s1/3.

Router# *configure terminal*

Router(config)# *interface s1/3 *

Router(config-if)# *bandwidth 512 *

Router(config-if)# *ip address 10.10.100.1 255.255.255.0 *

Router(config-if# *auto qos voip *

Router(config-if)# *exit *

**

*auto qos voip : Relies on NBAR *

*auto qos trust: Classifies based on dscp values .....*

*================================================================*

*where as AutoQos-Enterprise first discovers and then applies class-maps
and policy maps..based on discovered ..*
