Content Addressable Memory (CAM)
Overview
Content Addressable Memory (CAM) commands are supported C-Series, E-Series TeraScale and
S-Series, as indicated by the symbols under each command heading: c e
t
s.
This chapter includes the following sections:
• CAM Profile Commands
CAM Profile Commands
The CAM profiling feature enables you to partition the CAM to best suit your application. For
example:
• Configure more Layer 2 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 ACLs (when IPv6 is not employed).
• Hash MPLS packets based on source and destination IP addresses for LAGs.
• Hash based on bidirectional flow for LAGs.
• Optimize the 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
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.
Note: Not all CAM commands are supported on all platforms. Be sure to note the platform
symbol when looking for a command.
