Term Explanation
Stack-Unit
Lists the stack unit or units that are checked. Entering all shows the status for all
stacks.
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 profile of the CAM.
Available CAM Identifies the amount of CAM space remaining for that profile.
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
Unified Forwarding Table Modes
Unified Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts, and Layer 3
Route [Longest Prefix Match — LPM]) into a single flexible resource. The system 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 profile, 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 profiles. This profile must match the
system UFT mode profile (the profile on the primary route processor module [RPM]/ Master Unit of the Stack).
● Apply the UFT mode configuration to the entire system when you use the CONFIGURATION mode commands. Save the
running-configuration to affect the change.
● Save the changes and reboot the system for UFT mode profiling to take effect.
hardware forwarding-table mode
Select a mode to initialize the maximum scalability size for L2 MAC table or L3 Host table or L3 Route table.
