QoS packet classification
To manage network traffic using QoS features,
you must first classify (select) the packets you want to manage. You
can use any combination of the following packet classification methods
to select packets for QoS management:
Globally configured, switch-wide classification criteria
Classifier-based match criteria applied to inbound traffic on specific port and VLAN interfaces
NOTE:
Starting in software release K.14.01, global and classifier-based QoS policies support IPv6 and IPv4 packet classification.
