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 ACL
in 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 dierent VLAN services, use the show cam-acl-vlan command. After you
congure the ACL VLAN groups, reboot the system to store the settings in nonvolatile storage. During CAM initialization, the chassis
manager reads the NVRAM and allocates the dynamic VCAP regions.
Unied Forwarding Table (UFT) Modes
Unied Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts, and Layer 3 Route [Longest
Prex Match — LPM]) into a single exible resource. Dell EMC Networking OS supports several UFT modes to extract the forwarding
tables, as required. By default, Dell EMC Networking OS initializes the table sizes to UFT mode 2 prole, since it provides a reasonable
shared memory for all the tables. The other supported UFT modes are scaled-l3–hosts (UFT mode 3) and scaled-l3–routes (UFT mode 4).
Conguring UFT Modes
To congure the Unied Forwarding Table (UFT) modes, follow these steps.
1 Select a mode to initialize the maximum scalability size for L2 MAC table or L3 Host table or L3 Route table.
