With UBR (Unspecified Bit Rate), the bandwidth not used by other QoS features is used for
transmission. There are no specific requirements. Consequently, no bandwidth is reserved
with UBR.
With CBR (Constant Bit Rate), a fixed bandwidth is used for transmission.
With VBR-nrt and VBR-rt, a changing bandwidth within configured parameters is used.
Depending on which quality of service characteristic is selected in the QoS Class drop-down
menu, parameters can be specified in the four fields Min PCR (Peak Cell Rate), Max PCR, SCR
(Sustainable Cell Rate) and MBS (Maximum Burst Rate). The unit of these fields is specified in
cells. To change the parameters, you must convert the available bandwidth into cells. A cell con-
tains 424 bits.
Min PCR (Peak Cell Rate) and Max PCR define the minimum and maximum cell rates.
SCR (Sustainable Cell Rate) sets the average cell rate.
MBS (Maximum Burst Rate) determines for how many cells the maximum cell rate is to be
maintained.
VLAN Configuration
Details on the configuration of the VLAN interface can be obtained from Internet service pro-
vider.
Bridge Configuration
No configuration is required here.
Layer 2 configuration for the Physical setting WANoE
For the physical interface WANoE, you can define whether the specified port is to be used as a VLAN
or a bridge. To edit the settings, click on the pencil icon .
IP Settings
Set the parameters for PPPoE and StaticIP.
PPPoE
This sets up a point-to-point connection.
Specify the Status. Set the check mark if the data is valid. Without a check mark, the data is in-
valid. With the Idle Time (in seconds), you can specify the period of inactivity after which an ac-
tive Internet connection is to be cleared.
DHCP
IP addresses are obtained dynamically from network of the Internet service provider. No config-
uration is required for this.
StaticIP
The IP address for Internet access is static, i.e., assigned manually. To do this, enter the IP address
the network device and the IP address of the Default Gateway as well as at least one DNS Server.
Click Save.
Note
Note that specifying higher parameter values in the Min PCR, Max PCR, SCR and MBS
fields than those prescribed does not achieve a higher bandwidth! It could even result
in the parameters not being accepted and thus prevent the connection from being es-
tablished.
