auto discovery qos — QoS

Synopsis

auto discovery qos [trust]
no auto discovery qos

Configures

Auto QoS Autodiscovery

Default

Disabled

Description

This command enables the disovery and collecting of data for the configuration of AutoQoS. Using NBAR, this command can analyze the traffic on the network in order to produce a more relevant QoS configuration. You should let this command run a few days in order for the data collection to work. Once the system has collected enough data, disable this command with the no auto disovery qos command and then enable AutoQoS with the auto qos command. To view the QoS policy generated by this command, use the show auto qos command. This command was introduced in IOS 12.3(7)T.

trust

Optional. When used, this keyword tells AutoQoS that the DSCP (Differentiated Service Code Point) values of a packet can be trusted for packet classification. If the trust keyword is not used, AutoQoS relies solely on NBAR for DSCP values.
