This command adds to the specified class definition a match condition based on the destination IP 
address of a packet. The 

 is the name of an existing DiffServ class. The 

 

parameter specifies an IP address. The 

 parameter specifies an IP address bit mask; note 

that although similar to a standard subnet mask, this bit mask need not be contiguous. The optional 

 parameter has the effect of negating this match condition for the class (i.e., match all 

destination IP addresses except for what is specified here).

This command adds to the specified class definition a match condition based on the destination 
layer 4 port of a packet using a single keyword notation. The 

 is the name of an 

existing DiffServ class. The value for

 is one of the supported port name keywords

The currently supported 

 values are: 

. Each of these translates into its equivalent port number, which is used

destination layer 4 port range as a match criterion.

This command adds to the specified class definition a match condition based on the destination 
layer 4 port of a packet using a numeric notation. The 

 is the name of an existing 

DiffServ class. One layer 4 port number is required. The port number is an integer from 0 to 
65535. The optional

parameter has the effect of negating this match condition for the 

class (i.e., match all destination layer 4 port numbers except for the one specified here).
