QoS: Multiple Match Commands

The following list summarizes the key points regarding more complex matching options:

  • Up to four CoS and IPP or eight DSCP values can be listed on a single match cos, match precedence, or match dscp command
  • If a class map has multiple match commands in it, the match any or match all parameter on the class map defines whether a logical OR or a logical AND (default) is used between the match commands
  • the match class name command refers to another class map by name, nesting the named class map’s matching logic, the match class name command is considered to match if the referenced class map also results in a match to the traffic it defines.
