System Management
For ACL and QoS resources, the user has the option to allocate resources to limit
usage per feature, regardless of the match criteria used. The sum of all resources
used for different SAP ingress classification match-criteria is limited by the amount
of resources allocated for SAP ingress classification. The user can also allocate
resources by specific match criteria. The user can enable any supported match
criteria and associate a fixed amount of resources with each match criteria in fixed
sizes; the chunk size is dependent on the platform.
The system allocates resources based on the order of appearance in the
configuration file, and fails any match criteria if the system does not have any more
resources to allocate. In addition, the max keyword can be used to indicate that the
system needs to allocate resources when they are first required, as long as the
maximum amount of resources allocated for that feature is not exceeded or the
maximum amount of resources available in the system is not exceeded. The
7210 SAS platforms allocate resources to each feature and match-criteria in fixed-
size chunks.
The no form of the resource-profile command disables the use of the
corresponding match criteria or feature by deallocating all the resources allocated to
the criteria or feature. For example:
If the system successfully runs the no command, it frees up resources used by the
chunk or slice and make the resources, or the entire chunk/slice, available for use by
other features. Before deallocating resources, the software checks if a service object
is using the resource and fails the command if the object is in use. If resources are
in use, they can be freed up by deleting a SAP, removing a policy association with a
SAP, deleting a MEP, and so on. Some commands under the system resource-
profile context do not take effect immediately and require a system reboot before the
change occurs and resources are freed. The following is the handling of freed
resources.

1. Configuring the system resource-profile internal-ingress-tcam qos-sap-
ingress-resource no mac-match-enable command deallocates all the
resources allocated to SAP ingress QoS classification MAC match criteria. After
this command is run, users cannot associate a SAP ingress policy with MAC
match criteria defined to a SAP. Resources allocated to other criteria are
unaffected and can continue to be used.
2. Configuring the system resource-profile internal-ingress-tcam eth-cfm no
up-mep command deallocates all the resources allocated to CFM UP MEP.
After this command is run, user cannot configure UP MEP.
• If some entries in a slice are freed, they are made available for use by other
SAPs using the same feature to which the chunk is allocated.
• If an entire chunk is freed, it is returned to the system free pool for possible use
by other features.
