Description
This command allocates maximum resources for use by meters/policers used to implement SAP ingress
aggregate meter functionality from the global pool of ingress CAM resources. Before using the configure
service sap ingress aggregate-meter-rate command, the user must ensure that resources are allocated
to aggregate meters using this command.
Note:
For the command to take effect, the node must be restarted after making the change.
This command allocates meter resources from the available global ingress CAM resource pool. By default,
when resources are allocated to SAP ingress QoS policy, along with the CAM classification entries, meter
resources are also allocated. Hence, if the user needs to use SAP aggregate meter functionality they
cannot allocate all the available resources in the global resource pool to SAP ingress QoS policies and
ETH-CFM UP MEP. They need to allocate some resources for use by SAP aggregate meter (or SAP
ingress ACLs or G8032-fast-flood feature).
By default, when resources are allocated for ingress ACLs, only classification entries are used and meters
resources are not used. SAP aggregate meter resources can use meters from this pool of meter resources.
In other words, SAP aggregate meters are stolen from the unused meters in the resources allocated to
ingress ACLs.
If the user allocates resources for ingress ACLs and configures resources for SAP aggregate meter using
this command, the software does the following.
• It does not allocate any additional resources from the available global ingress CAM resource pool
to SAP aggregate meter, if it can allocate the required number of meters from the chunks/resources
allocated to ingress ACLs. For example, if the user has allocated 2 chunks of 512 entries each for
ingress ACLs and then configures sap-aggregate-meter to use 2 chunks to use about 512 aggregate
meters, the software will not allocate any additional entries from the available global resource pool.
• If the number of ingress ACL resources allocated by user is less than the number of resources assigned
by the user to sap-aggregate-meter, then it allocates the difference from the available global ingress
CAM resource pool. For example, if the user has allocated 1 chunk of 512 entries for ingress ACLs and
then configures sap-aggregate-meter to use 2 chunks to use about 512 aggregate meters, the software
will allocate 1 additional chunk (2 chunks required for SAP aggregate - 1 chunk alloted to ingress ACLs)
for use with SAP aggregate meter. The classification entries associated with additional chunk alloted for
