Managed Switch CLI Manual, Release 8.0.3
Quality of Service (QoS) Commands 8-13
v1.0, July 2010
no match class-map
This command removes from the specified class definition the set of match conditions defined for
another class. The <refclassname> is the name of an existing DiffServ class whose match
conditions are being referenced by the specified class definition.
match cos
This command adds to the specified class definition a match condition for the Class of Service
value (the only tag in a single tagged packet or the first or outer 802.1Q tag of a double VLAN
tagged packet). The value may be from 0 to 7.
Note:
• The parameters <refclassname> and <class-map-name> can not be the same.
• Only one other class may be referenced by a class.
• Any attempts to delete the <refclassname> class while the class is still referenced by any <class-
map-name> fails.
• The combined match criteria of <class-map-name> and <refclassname> must be an allowed
combination based on the class type.
• Any subsequent changes to the <refclassname> class match criteria must maintain this validity, or
the change attempt fails.
• The total number of class rules formed by the complete reference class chain (including both
predecessor and successor classes) must not exceed a platform-specific maximum. In some
cases, each removal of a refclass rule reduces the maximum number of available rules in the
class definition by one.
