10.5 Service classes
SCALANCE XM-400/XR-500 Command Line Interface (CLI)
672 Configuration Manual, 11/2015, C79000-G8976-C252-10
Call up the command with the following parameters:
cos-map <cos(0-7)> queue <queue(1-8)>
The parameters have the following meaning:
Keyword for a queue -
Queue that it is assigned to this service
class
1 … 8
The service classes (COS) are assigned to the queues as follows:
COS 0 → Queue 2
COS 1 → Queue 1
COS 2 → Queue 3
COS 3 → Queue 4
COS 4 → Queue 5
COS 5 → Queue 6
COS 6 → Queue 7
COS 7 → Queue 8
The assignment table for service classes is configured.
In a network, each IP packet is assigned a DSCP code that decides its priority. In special
situations, it may be necessary to change this priority.
This change is made using a table in which the DSCP codes are assigned to another queue.
With this command, you configure the assignment table for DSCP codes.
With queues 1 - 6 frames with a lower priority are occasionally processed even if there are
frames with high priority in the queue.
With queues 7 - 8 only frames with a high priority are processed as long as there are frames
with high priority in the queue.
You are in the QOS configuration mode.
The command prompt is as follows:
cli(config-qos)#
