QoS Attributes for POS LPorts
The Add Logical Port dialog box QoS tab enables you to configure logical port
Quality of Service (QoS) parameters. To review QoS parameters and, if necessary,
modify these defaults, refer to the instructions in this section.
This section describes how to set the logical port Quality of Service (QoS) parameters.
These parameters enable you to specify the bandwidth and routing metrics (if
applicable) for the various traffic service classes. By setting logical port QoS
Parameters, you can allocate bandwidth for circuits based on their QoS services on a
logical port.
Lucent recommends that you set the logical port QoS fixed and dynamic options
before you provision circuits. Under certain conditions, if you change the bandwidth
from dynamic to fixed after you provision circuits, one or more QoS classes may
display negative bandwidth.

POS LPorts
Field
Description
Bandwidth
Enter the amount of bandwidth you want to configure for this
logical port. The default is the amount of bandwidth remaining from
the physical clock rate, less any logical ports already configured.
CRC Checking
Set this value to match the number of error checking bits used by the
CPE connected to this port. Performs a cyclic redundancy check
(CRC) on incoming data.
Select one of the following options:
•
CRC 16 - Data will be checked in 4K frames.
•
CRC 32 - Data will be checked in 8K frames.
