About global IP-device classifier

Global QoS classifier precedence: 2

The global IP-device classifier enables you to configure up to 300 IP addresses to select IP packets

according to source or destination address.

NOTE: IPv6 Support: Starting in software release K.14.01, IP device classifiers are supported

on IPv4,IPv6, and IPv4/IPv6 subnets. In previous releases, only IPv4 packets are supported.

When a globally-configured IP-device address has the highest precedence in the switch for traffic

addressed to or from the device, traffic received on the switch with the configured IP address is

marked with the specified priority level. You can configure different IP-device classifiers with different

priority levels.

NOTE: QoS IP-Device Restriction: The configuration of a QoS IP-device priority on the Management

VLAN IP address (if configured) is not supported. If no Management VLAN is configured, the

configuration of a QoS IP-device priority on the default VLAN IP address is not supported.
