Content Addressable Memory (CAM)
Content addressable memory (CAM) commands are supported on the Dell Networking MXL 10/40GbE
Switch IO Module.
WARNING: If you are using these features for the first time, contact Dell Networking Technical
Assistance Center (TAC) for guidance.
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).
• Optimize the virtual local area network (VLAN) ACL Group feature, which permits group VLANs for IP
egress ACLs.
Important Points to Remember
• The Dell Networking Operating System (OS) versions 7.8.1.0 and later support CAM allocations on the
MXL 10/40GbE Switch IO Module.
• The CAM configuration is applied to the entire system when you use the CONFIGURATION mode
commands. 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.
cam-acl (Configuration)
Select the default CAM allocation settings or reconfigure a new CAM allocation for Layer 2, IPv4, and IPv6
ACLs, Layer 2 and Layer 3 (IPv4) QoS, Layer 2 Protocol Tunneling (L2PT), IP and MAC source address
validation for DHCP, Ethernet Connectivity Fault Management (CFM) ACLs, and Policy-based Routing
(PBR).
