Term Explanation
Portpipe Lists the portpipe (port-set) or port pipes (port-sets) that are checked. Entering all
shows the status for stack-units and port-pipes in the chassis. The port set value is from
0 to 0.
CAM Partition Shows the CAM prole of the CAM.
Available CAM Identies the amount of CAM space remaining for that prole.
Estimated CAM per
Port
Estimates the amount of CAM space the listed policy will require.
Status Indicates whether or not the policy will be allowed in the CAM.
Example
Dell# test cam-usage service-policy input In stack-unit all

--------------------------------------------------------------------------------------
0 | 0 | IPv4Flow | 102 | 0| Allowed

Unied Forwarding Table 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. The system supports several UFT modes to extract the forwarding tables, as
required. By default, Dell Networking OS initializes the table sizes to UFT mode 2 prole, as 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).
Important Points to Remember
• All line cards/Stack Members within a single system must have the same UFT mode proles. This prole must match the system UFT
mode prole (the prole on the primary route processor module [RPM]/ Master Unit of the Stack).
• Apply the UFT mode conguration to the entire system when you use the CONFIGURATION mode commands. Save the running-
conguration to aect the change.
• Save the changes and reboot the system for UFT mode proling to take eect.
