QoS Limitations
The Cisco MWR 2941 offers different QoS support according to the physical interface and traffic type.
The following sections describe the limitations for each QoS capability on the Cisco MWR 2941.
• General QoS Limitations
• Statistics Limitations
• Propagation Limitations
• Classification Limitations
• Marking Limitations
• Congestion Management Limitations
• Shaping Limitations
General QoS Limitations
The following general QoS limitations apply to the Cisco MWR 2941.
• You can create a maximum of 32 class maps including the class-default class map.
• You can create a maximum of 32 policy-maps.
• Congestion Avoidance, including Weighted Random Early Detection (WRED) is not supported.
• The following limitations apply to MLPPP interfaces:
–
You can implement MLPPP Ingress DSCP-to-CoS marking ony by using an egress SVI
interface.
–
You can apply only one output QoS service policy to an MLPPP interface.
–
You can create a maximum of 8 match statements within a class map in a service policy applied
to an MLPPP interface.
–
When applying or modifying any aspect of a service-policy on an MLPPP interface, you must
shut down and re-enable the interface.
–
You can create a maximum of 8 classes within a policy-map that is applied to an MLPPP
interface. This number includes the default-class.
–
You can have only 1 priority class within a policy-map applied to an MLPPP interface.
• The following limitations apply to GigabitEthernet interfaces:
–
You can apply a maximum of 3 different service policies to GigabitEthernet interfaces
–
You can only use the class-default class for HQoS parent service policies applied to egress
GigabitEthernet interfaces.
Statistics Limitations
• Input service policies on the GigabitEthernet interface support statistics based on class map and in
terms of packets. Statistics based on filters and statistics in terms of bytes or rates are not supported.
