About QoS
QoS operation
On the switches covered in this guide, QoS operation may be configured through a combination
of the following methods:
• Globally-configured, switch-wide QoS settings
• Classifier-based per-port and per-VLAN QoS policies.
Classifier-based QoS policies are designed to work with existing globally-configured, switch-wide
QoS settings by allowing you to zoom in on a subset of port or VLAN traffic to further manage it.
You can use multiple match criteria to more finely select and define the classes of traffic that you
want to manage. QoS policy actions determine how you can handle the selected traffic.
NOTE: While providing greater control for implementing QoS policies, classifier-based QoS
policies may override globally-configured QoS settings.
Carefully plan your QoS strategies in advance, identifying the network traffic that you can globally
configure and the traffic on which you want to execute customized, classifier-based QoS actions.
Globally-configured QoS
Globally-configured QoS operation supports the following types of packet classification and traffic
marking on outbound port and VLAN traffic.
• Globally configured packet classification criteria include:
IPv4 device: source and destination address•
• Layer 2 802.1p priority (VLAN header)
• Layer 3 protocol (such as ARP, IP, IPX, RIP)
• Layer 3 IPv4 Type of Service (ToS) byte: IP precedence or DSCP bits
• Layer 3 IPv6 Traffic Class byte: IP precedence or DSCP bits
• Layer 4 UDP/TCP application port
