To reset the number of FP blocks to the default, use the no version of these commands. By default, zero groups are allocated for the ACLin VCAP. ACL VLAN groups or CAM optimization is not enabled by default. You must also allocate the slices for CAM optimization.To display the number of FP blocks that is allocated for the different VLAN services, use the show cam-acl-vlan command. After youconfigure the ACL VLAN groups, reboot the system to store the settings in nonvolatile storage. During CAM initialization, the chassismanager reads the NVRAM and allocates the dynamic VCAP regions.Unified Forwarding Table (UFT) ModesUnified Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts, and Layer 3 Route [LongestPrefix Match — LPM]) into a single flexible resource. Dell Networking OS supports several UFT modes to extract the forwarding tables, asrequired. By default, Dell Networking OS initializes the table sizes to UFT mode 2 profile, since it provides a reasonable shared memory forall the tables. The other supported UFT modes are scaled-l3–hosts (UFT mode 3) and scaled-l3–routes (UFT mode 4).Table 7.
