The GGSN QOS Mapping category of the Chassis Configuration dialog box displays the mapping of different QoS classes to the ToS precedence classes in the IP header.
Note This dialog can be viewed if cGtpGSNService is set to 'ggsn'. This table is empty if 'cggsnQosMappingMethod' is set to 'none'.
Right-click the device and then select Configure, or double-click the device.
Select GGSN QOS Mapping from the Category list.
The following information appears:
Different
QOS Classes (cggsnQosClass)
IP
TOS Precedence (cggsnQosMappedIpTos)
Specifies the different QoS classes of canonical or delay QoS, based on the value set to cggsnQosMappingMethod. The value is interpreted as shown in the tables:
If cggsnQosMappingMethod is set to delay(3):
Value |
Interpretation |
1 |
delay1 |
2 |
delay2 |
3 |
delay3 |
4 |
delay_best_effort |
If cggsnQosMappingMethod is set to canonical(2):
Value |
Interpretation |
1 |
premium |
2 |
normal |
3 |
best_effort |
IP ToS precedence to which cggsnQosClass is mapped. The service priority is directly proportional to the ToS precedence; that is, the higher the ToS precedence, the higher the service priority. ToS values of 6 (internetwork_control) and 7 (network_control) are not used in mapping.
