Content Addressable Memory (CAM)
Content addressable memory (CAM) commands are supported on the Dell Force10 E-Series TeraScale, C-Series, S-
Series, Z-Series, or S4810 platforms.
NOTE: Not all CAM commands are supported on all platforms. Be sure to note the platform when looking for a
command.
WARNING: If you are using these features for the first time, contact Dell Force10 Technical Assistance Center
(TAC) for guidance. For information about contacting Dell Force10 TAC, visit the Dell Force10 website at

CAM Profile Commands
The CAM profiling feature allows you to partition the CAM to best suit your application. For example:
•
Configure more Layer 2 forwarding information base (FIB) entries when the system is deployed as a switch.
•
Configure more Layer 3 FIB entries when the system is deployed as a router.
•
Configure more access control lists (ACLs) (when IPv6 is not employed).
•
Hash multi-protocol label switching (MPLS) packets based on source and destination IP addresses for link
aggregation groups (LAGs).
•
Hash based on bidirectional flow for LAGs.
•
Optimize the virtual local area network (VLAN) ACL Group feature, which permits group VLANs for IP egress
ACLs.
Important Points to Remember
•
CAM Profiles are available on FTOS versions 6.3.1.1 and later for the E-Series TeraScale.
•
FTOS versions 7.8.1.0 and later support CAM allocations on the C-Series and S-Series.
•
All line cards within a single system must have the same CAM profile (including CAM sub-region
configurations); this profile must match the system CAM profile (the profile on the primary route processor
module [RPM]).
•
FTOS automatically reconfigures the CAM profile on line cards and the secondary RPM to match the system
CAM profile by saving the correct profile on the card and then rebooting it.
•
The CAM configuration is applied to the entire system when you use the CONFIGURATION mode commands.
You must save the running-configuration to affect the change.
•
When budgeting your CAM allocations for ACLs and quality of service (QoS) configurations, remember that ACL
and QoS rules might consume more than one CAM entry depending on complexity. For example, transmission
control protocol (TCP) and user datagram protocol (UDP) rules with
port range
options might require more
than one CAM entry.
•
After you install a secondary RPM, copy the running-configuration to the startup-configuration so that the new
RPM has the correct CAM profile.
•
You MUST save your changes and reboot the system for CAM profiling or allocations to take effect.
