Common Policies menu parameters
Default
The Default parameter specifies whether a parameter is set to the default value or can be configured.
The options are:
When the Default parameter is set to enabled, you cannot configure the associated parameters.
Destination IP Prefix
The Destination IP Prefix parameter specifies a list of IP prefixes to use as destinations for the filter policy. When the parameter is enabled, click on the Select button and choose a prefix list.
Log ID
The Log ID parameter specifies the filter log for the filter entry. Click on the Select button beside the parameter to choose a filter, or type in a value. The range is 101 to 199. The default is 0, which means that the parameter is not configured.
New Entry ID
The New Entry ID parameter specifies the new identifier of the filter entry. The parameter value becomes the Entry ID of the filter entry. A filter policy compares the contents of a packet to each filter entry until it finds a match, beginning with the lowest Entry ID. The range is 1 to 65535. There is no default.
Override CIR
The Override CIR parameter specifies the override value for the administrative committed information rate for the queue or the policer. The default is MAX which specifies the maximum available CIR.
The CIR override is configured in kbps if the Rate Type for the queue or policer was originally set to kbps. The CIR override is configured as a Percent (%) if the Rate Type for the queue or policer was originally set to either Percent Port Limit (queues only) or Percent Local Limit.
The range depends on the type of object being configured.

|
Object type |
Range |
|---|---|
|
Queue |
The range is 0 to 100 000 000 kbps (0 to 100%), depending on the line rate of the object to which the policy is applied. A value of -2 specifies that no override is applied. A value of -1 specifies that the maximum override is applied. |
|
Policer |
The range is 0 to 20 000 000 kbps (0 to 100%), depending on the line rate of the object to which the policer is applied. A value of -2 specifies that no override is applied. A value of -1 specifies that the maximum override is applied. |
Override CIR Adaptation
The Override CIR Adaptation parameter specifies the override value for the method used by the device to derive the operational CIR setting when the queue is provisioned in hardware
You can also choose the Default option, which specifies that the operational CIR for the queue is the rate closest to the rate specified by the CIR (kbps) parameter.

|
Max |

Override Committed Burst Size
The Override Committed Burst Size parameter specifies the override value for the Committed burst pool size for a queue.
The range is -1 to 4 194 304, with -1 indicating default. Default specifies that the device calculates committed burst pool size based on the CIR and the PIR. The default is default.
Override High Priority Reserved
The Override High Priority Reserved parameter specifies the override value for the percentage of buffer pool space for the queue that is only used by high-priority packets.
The range is -1 to 100, with -1 indicating default. The default is default, which means that the device calculates the high priority reserved pool size based on the CIR and the PIR values.
Override Maximum Burst Size
The Override Maximum Burst Size parameter specifies the override value for the maximum burst pool size for a queue.
The range is -1 to 4 194 304, with -1 indicating default. Default specifies that the device calculates the committed burst pool size based on the CIR and PIR.
Override Packet Offset
The Override Packet Offset parameter specifies the number of offset bytes to add to (or remove from) a packet handled by a policer. A positive number adds bytes. A negative number removes bytes. The range is -128 and -32 to 31. The -128 value indicates that no override is applied. The default is -1.
Override PIR
The Override PIR parameter specifies the override value for the administrative peak information rate for the queue or the policer. The default is MAX which specifies the maximum available PIR.
For policers and non-HSMDA queues, the PIR override is configured in kbps if the Rate Type for the queue or policer was originally set to kbps. The PIR override is configured as a Percent (%) if the Rate Type for the non-HSMDA queue or policer was originally set to either Percent Port Limit (queues only) or Percent Local Limit.
The range depends on the type of object being configured.

HSMDA queue |
The range is 0 to 100 000 000 kbps, depending on the line rate of the object to which the policy is applied. A value of -2 specifies that no override is applied. A value of -1 specifies that the maximum override is applied. |
|
Queue |
The range is 0 to 100 000 000 kbps (0 to 100%), depending on the line rate of the object to which the policy is applied. A value of -2 specifies that no override is applied. A value of -1 specifies that the maximum override is applied. |
|
Policer |
The range is 0 to 20 000 000 kbps (0 to 100%), depending on the line rate of the object to which the policer is applied. A value of -2 specifies that no override is applied. A value of -1 specifies that the maximum override is applied. |
Override PIR Adaptation
The Override PIR Adaptation parameter specifies the override value for the method used by the device to derive the operational PIR setting when the queue is provisioned in hardware
You can also choose the Default option, which specifies that the operational PIR for the queue is the rate closest to the rate specified by the PIR (kbps) parameter.

Override Port Average Overhead
The Override Port Average Overhead parameter specifies the override value for the average percentage that the offered load to a queue is expected to expand during the frame encapsulation process before sending traffic on queues that egress a SONET or SDH port or channel.
The range is 0 to 100. Default specifies that the egress QoS policy for the queue is applied.
Override Queue CIR Weight
The Override Queue CIR Weight parameter specifies the override value for the weight that should be assigned to this queue by the parent scheduler among all the entities feeding into the parent when the traffic is conforming to the committed rate.
The range is -2 to 100. Default specifies that the egress or ingress QoS policy for the queue is applied. A value of '0' specifies that the queue will not receive bandwidth for the 'within-cir' pass on its parent scheduler.
Override Queue Weight
The Override Queue Weight parameter specifies the weight that needs to be used by the scheduler to which this queue would be feeding.
