Because resources are shared, the user must ensure that the sum total of such
resources does not exceed the limit supported by the IMM or node. If the system
determines that it cannot allocate the requested resources, the feature is disabled.
For example, if the system determines that it cannot allocate resources for g8032-
fast-flood, it disables the feature from use and G8032 eth-rings will not be able to use
fast-flood mechanisms). Another example is the case where the system determines
that it cannot allocate resources for IPv4-based SAP Ingress ACL classification, the
system will not allow users to use IPv4-based SAP ingress ACL classification feature
and fails the configuration when it comes upon the first SAP in the configuration file
that uses an IPv4-based SAP ingress ACL policy.
For boot-time parameters, such as g8032-fast-flood-enable, the user must ensure
that the configured services match the resources allocated. If the system determines
that it cannot allocate resources to services, it fails the configuration file at the first
instance where it encounters a command to which resources cannot be allocated.
The available resources can be allocated to different features.
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:
Note: The order in which the command appears in the configuration file is important.
