Usage Information Example Version 7.4.1.0 Introduced on the E-Series. This features allows you to determine if the CAM has enough space available before applying the configuration on an interface. An input policy map with both Trust and Class-map configuration, the Class-map rules are ignored and only the Trust rule is programmed in the CAM. In such an instance, the Estimated CAM output column will contain the size of the CAM space required for the Trust rule and not the Class-map rule. The following describes the text cam-usage service-policy input policymap linecard command shown in the Example below. Field Description Linecard Indicates the line card slot number. Portpipe Indicates the portpipe number. CAM Partition The CAM space where the rules are added. Available CAM Indicates the free CAM space, in the partition, for the classification rules. NOTE: The CAM entries reserved for the default rules are not included in the Available CAM column; free entries, from the default rules space, can not be used as a policy map for the classification rules. Estimated CAM per Port Indicates the number of free CAM entries required (for the classification rules) to apply the input policy map on a single interface. NOTE: The CAM entries for the default rule are not included in this column; a CAM entry for the default rule is always dedicated to a port and is always available for that interface. Status (Allowed ports) Indicates if the input policy map configuration on an interface belonging to a linecard/port-pipe is successful-Allowed (n)-or not successful- Exception. The allowed number (n) indicates the number of ports in that port-pipe on which the Policy Map can be applied successfully. NOTE: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed; therefore, the output contains only L2ACL CAM partition entries. FTOS# test cam-usage service-policy input pmap_l2 linecard all For a L2 Input Policy Map pmap_l2, the output must be as follows, Linecard|Portpipe|CAM Partition|Available CAM|Estimated CAM| Status | | | |per Port | (Allowed ports) 0 0 L2ACL 500 200 Allowed (2) 0 1 L2ACL 100 200 1229
