Global QoS classifier precedence: 2
The IP device option, which applies only to IPv4 packets, enables you to use up to 300 IP addresses (source or destination) as QoS classifiers.
Where a particular device-IP address classifier has the highest precedence in the switch for traffic addressed to or from that device, then traffic received on the switch with that address is marked with the IP address classifier’s configured priority level. Different IP device classifiers can have differing priority levels.
NOTE:
QoS IP-device restriction: The switch does not allow a QoS IP-device priority for the Management VLAN IP address (if configured). If no Management VLAN is configured, then the switch does not allow configuring a QoS IP-device priority for the default VLAN IP address.
