Adding a CoS Value to a Class Map
Choosing the CoS value allows you to add the user priority level to a class
map as a matching criterion. You assign a CoS value according to the
type of traffic that you want to filter, such as voice traffic. Then you add the
CoS value to a class map with the MATCH COS command. For more
information about this command, see "MATCH COS" on page 1609.
Table 197 provides a summary of guidelines from the IEEE Standard
802.1d on applying priorities to traffic types.
