Configuring QoS Class Maps

The following examples pertain specifically to QoS class maps.

Configuring or Modifying a Class Map

You can create or modify a class map then reference class maps in policy maps.

Note: You cannot create a queuing class map; you must use one of the system-defined queuing class maps.

CLI Command

The CLI command below is the equivalent to the payload example displayed in the pane on the right. Click the DME tab in the top-left corner of the right pane to view the JSON payload or the YANG tab to view the XML payload.

Configuring IP RTP Classification

The IP Real-time Transport Protocol (RTP) is a transport protocol for real-time applications that transmit data such as audio or video and is defined by RFC 3550. Although RTP does not use a common TCP or UDP port, you typically configure RTP to use ports 16384 to 32767. UDP communications uses an even-numbered port and the next higher odd-numbered port is used for RTP Control Protocol (RTCP) communications.

You can configure classification based on UDP port ranges, which are likely to target applications using RTP.

CLI Commands

class-map class_cos
match IP rtp 3000

Note: The property information for this example was added in Release 9.3(3).
