Auto QoS Autodiscovery
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.
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.
