Content Addressable Memory (CAM)
Content addressable memory (CAM) commands are supported on the S5000 switch.
CAM Profile Commands
The CAM profiling feature allows you to partition the CAM to best suit your application. For example:
Configure more Layer 2 ACL entries when the system is deployed as a switch.
Configure more Layer 3 ACL entries when the system is deployed as a router.
Configure more FCoE or iSCSI ACLs to handle an increase in storage traffic.
Important Points to Remember
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.
You MUST save your changes and reboot the system for CAM profiling or allocations to take effect.
cam-acl (Configuration)
Reset CAM allocation to default settings or reconfigure 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 (optionally) FCoE and iSCSI ACLs.
