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 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.

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. Trident 2 supports several
UFT modes to extract the forwarding tables, as required. By default, Dell Networking OS initializes the table
sizes to UFT mode 2 profile, 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).
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).
• The UFT mode configuration is applied to the entire system when you use the CONFIGURATION mode
commands. Save the running-configuration to affect the change.
• You MUST save your 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.
Syntax
hardware forwarding-table mode {scaled-l3- hosts | scaled-l3-
routes}
Parameters
scaled-l3–
hosts
Enter the keywords scaled-l3–hosts to select the forwarding
table mode for scaling l3 host entries.
