The QoS domainincludes the switch, the network interior, <strong>and</strong> edge devices that can classify incoming traffic for QoS.Auto-QoS configures the switch for connectivity with a trusted interface. The QoS labels of incomingpackets are trusted. For nonrouted ports, the CoS value of the incoming packets is trusted. For routedports, the DSCP value of the incoming packet is trusted.To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoScomm<strong>and</strong>s. You can fine-tune the auto-QoS configuration after you enable auto-QoS.This is the policy map when the auto qos classify comm<strong>and</strong> is configured:policy-map AUTOQOS-SRND4-CLASSIFY-POLICYclass AUTOQOS_MULTIENHANCED_CONF_CLASSset dscp af41class AUTOQOS_BULK_DATA_CLASSset dscp af11class AUTOQOS_TRANSACTION_CLASSset dscp af21class AUTOQOS_SCAVANGER_CLASSset dscp cs1class AUTOQOS_SIGNALING_CLASSset dscp cs3class AUTOQOS_DEFAULT_CLASSset dscp defaultThis is the policy map when the auto qos classify police comm<strong>and</strong> is configured:policy-map AUTOQOS-SRND4-CLASSIFY-POLICE-POLICYclass AUTOQOS_MULTIENHANCED_CONF_CLASSset dscp af41police 5000000 8000 exceed-action dropclass AUTOQOS_BULK_DATA_CLASSset dscp af11police 10000000 8000 exceed-action policed-dscp-transmitclass AUTOQOS_TRANSACTION_CLASSset dscp af21police 10000000 8000 exceed-action policed-dscp-transmitclass AUTOQOS_SCAVANGER_CLASSset dscp cs1police 10000000 8000 exceed-action dropclass AUTOQOS_SIGNALING_CLASSset dscp cs3police 32000 8000 exceed-action dropclass AUTOQOS_DEFAULT_CLASSset dscp defaultpolice 10000000 8000 exceed-action policed-dscp-transmitOL-9776-08<strong>Catalyst</strong> <strong>3750</strong>-E <strong>and</strong> <strong>3560</strong>-E <strong>Switch</strong> Comm<strong>and</strong> Reference2-51
