14. To configure the class details, complete the fields:
• Class Name - The name for the configured DiffServ class.
• Class Type - The DiffServ class type.
You can select the class type only when you are creating a new class. After you
create the class, this field displays the class type, but you cannot change it.
15. Define the criteria to associate with a DiffServ class:
• Match Every. This adds to the specified class definition a match condition whereby all
packets are considered to belong to the class.
• Reference Class. This lists the class(es) that can be assigned as reference class(es)
to the current class.
• Class of Service. This lists all the values for the Class of Service match criterion in
the range 0 to 7 from which one can be selected.
• VLAN. This is a value in the range of 0–4093.
• Secondary Class of Service. Select this option to require the Class of Service (CoS)
value in an Ethernet frame header to match the specified CoS value.
• Secondary VLAN. Select this option to require a packet’s VLAN ID to match a
secondary VLAN ID or a secondary VLAN ID within a continuous range. If you
configure a range, a match occurs if a packet’s secondary VLAN ID is the same as
any secondary VLAN ID within the range. After you select this option, use the
following fields to configure the secondary VLAN match criteria:
- Secondary VLAN ID Start. The secondary VLAN ID to match or the secondary
VLAN ID with the lowest value within a range of VLANs.
- Secondary VLAN ID End. The secondary VLAN ID with the highest value within
the range of VLANs. This field is not required if the match criteria is a single VLAN
ID.
