Note: The srcl4port keyword, number, and range commands are alternative ways to specify a 
source layer 4 port range as a match criterion.

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

 is the name of an existing DiffServ class. Two layer 4 port 

numbers are required and together they specify a contiguous port range. Each port number is an 
integer from 0 to 65535, but with the added requirement that the second number be equal to or 
greater than the first. The optional 

 parameter has the effect of negating this match 

condition for the class (i.e., match all source layer 4 ports except for those within the range 
specified here).

parameter is any layer 2 MAC address formatted as six, two-digit hexadecimal numbers separated 
by colons (e.g., 00:11:22:dd:ee:ff). The 

 parameter is a layer 2 MAC address bit mask, 

which need not be contiguous, and is formatted as six, two-digit hexadecimal numbers separated 
by colons (e.g., ff:07:23:ff:fe:dc). The optional 

parameter has the effect of negating 

this match condition for the class (i.e., match all source MAC addresses except for what is 
specified here).
