typically want to use different features. Therefore, ingress internal TCAM resource allocation

capabilities has been extended to the egress internal TCAM resources.

For more details about individual commands and features that use System Resource Allocation.

Please see the CLI descriptions and the feature description in the respective user guides.

NOTE: Boot-time commands under the config> system> resource-profile will not take effect

when a configuration file is executed using the 'exec' CLI command. Boot-time commands under

the config> system> resource-profile are read and acted upon by the system only during boot.

System Resource Allocation Examples

Example one:

config> system> resource-profile...

acl-sap-ingress 3

mac-match-enable max

ipv4-match-enable 1

no ipv6_128-ipv4-match-enable

no ipv6_64-only-match-enable

exit

…..

In the above example CLI, the system takes the following actions:

• System allocates 3 chunks for use by the SAP ingress ACL entries.

• System allocates 1 chunk for use by SAP ingress ACL entries using ipv4-criteria. The

system fails the configuration when the number of ACL entries using ipv4-criteria

exceeds the configured limit (that is, the system does not allocate in excess of the

configured limit of 1 chunk).

• System allocates a chunk for use by SAP ingress ACL entries using mac-criteria. After the

user has specified 'max', the system allocates 1 chunk for use when the user associates an

ingress ACL policy (with mac-criteria entries defined) with a SAP. The system can

allocate more chunks, up-to 2 chunks, as the user has specified the ‘max’ keyword. More

chunks are allocated when user configures SAP that use mac-criteria and all of the entries

in the allocated chunk(s) is used up. The system fails the configuration when the number

of ACL entries with mac-criteria exceeds the limit of 2 chunks allocated to SAP ingress

ACL match (that is, the system does not allocate in excess of the configured limit of 3

chunks = up-to 2 for mac-criteria and 1 for ipv4-criteria).

• The system fails user attempt to use SAP ingress ACLs with ipv6 match criteria (and the

other combinations listed above), as the user has disabled the use of these criteria.
