9.4.5 match class-map
This command adds to 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.
Note: there is no [
not
]
option for this match command.
Default
none
Format match class-map

Restrictions
The class types of both <
classname>
and <
refclassname>
must be identical (i.e.,
any vs. any, or all vs. all). A class type of acl is not supported by this command. Cannot specify
<refclassname>
the same as <
classname>
(i.e., self-referencing of class name not allowed).
At most one other class may be referenced by a class.
Any attempt to delete the <
refclassname>
class while still referenced by any <
classname
> shall
fail. The combined match criteria of <
classname>
and <
refclassname>
must be an allowed
combination based on the class type. Any subsequent changes to the <
ref-classname>
class
match criteria must maintain this validity, or the change attempt shall fail.
The total number of class rules formed by the complete reference class chain (includes 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.
9.4.5.1 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. Note: there is no [
not]
option for
this match command.

9.4.6 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. The optional [
not]
parameter has the effect of
negating this match condition for the class (i.e., match all class of service values except for what is
specified here).
