Classifier-based traffic marking

QoS on the switches covered in this guide support these types of traffic marking:

  • 802.1p prioritization: Controls the outbound port queue priority for traffic leaving the switch, and (if traffic exits through a VLAN-tagged port) sends the priority setting in packet headers to downstream devices.
  • IP Type-of-Service (ToS): Enables the switch to set, change, and honor prioritization policies by using the Differentiated Services (diffserv) bits in the ToS byte of IPv4 packet headers.
