A DDING CLASSES
A class contains criteria according to which the data packets are analysed and classified:
• IP: for IP packets
• Ethernet: for Ethernet frames
• VLAN: for VLAN packets
In addition to these three criteria, the MAC addresses can also be included as criterion.
Now it is possible to further differentiate by means of the following criteria:
Internet protocol
Transport Protocol included in the IP packet: TCP/UDP/ICMP or *
for all.
Ethernet protocol Protocol number specified in hexadecimal. Values between 0x0600
– 0xFFFF are admissible.
IP Type of Service The Internet Protocol specifies a prioritization in this field which can
be evaluated here and used as a criterion.
VLAN ID Clear ID-number of a VLAN. If 0 is chosen, the VLAN QoS is
evaluated.
VLAN QoS Values from 0 to 7 indicating prioritization. Is only evaluated if VLAN
ID = 0.
MAC addresses Target and source MAC address.
IP addresses Target and source IP address with net mask.
Port number Port number, if TCP or UDP was chosen.
Then the name, bit rate and priority have to be defined for each class. In this connection,
make sure that the sum of all class bit rates does not exceed the interface bit rate. For
priority, values between 0 (high) and 7 (low) are given.
If no class can be found for a data type, priority 7 is automatically allocated and the
remaining bit rate is used.
Note:
If all criteria fields are left empty and this rule is added at the end of the table, the
behaviour which is normally not applied to non-classified data types can be adapted.
E XAMPLE
In the above example the maximum bit rate of the interface is set at 5Mbit/s. This bit rate
is shared by three classes. The first class with a low priority and a bit rate of only 0.5Mbit/s
describes normal HTTP connections. The second class is reserved for VoIP connections
with 3.5Mbit/s and highest priority. The third class is the Default class (not configured)
covering the residual data traffic to which the remaining 1Mbit/s are allocated.

EACTIVATING P RIORITIZATION
All interfaces can be deactivated under menu item „Configuration  Prioritization“. For
this purpose remove the tick „Activate prioritization“.
