Auto QoS Discovery

Auto-Discovery


Started with the command:
(config-if)# auto discovery qos [trust]

Trust mode 


auto-discovery trusts the DSCP values in the IP header and uses it to classify packets, collect bandwidth statistics, calculate traffic average and traffic peak rate, then passes the data to the template module.

Untrust mode
auto-discovery uses NBAR to detect application on the network to collect data and perform statistical analysis.

To show the data that has been collected:
# show auto discovery qos [interface [interface type]]
