This command adds to the specified class definition a match condition based on the source 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 it resembles 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 source IP addresses except for what is specified here).

This command adds to the specified class definition a match condition based on the source layer 4

is one of the supported port name keywords (listed

The currently supported 

 values are: 

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

This command adds to the specified class definition a match condition based on the source layer 4

 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 source layer 4 
ports except for the one specified here).
