Command Line Reference Guide

Content Addressable Memory (CAM) | 383
Usage
Information
You must save the new CAM settings to the startup-config (write-mem or copy run start) then reload
the system for the new settings to take effect.
The total amount of space allowed is 16 FP Blocks. System flow requires 3 blocks and these cannot be
reallocated.
When configuring space for IPv6 ACLs, the total number of Blocks must equal 13.
Ranges for the CAM profiles are 1-10, except for the ipv6acl profile which is 0-10. The ipv6acl
allocation must be a factor of 2 (2, 4, 6, 8, 10).

Usage
Information
When this command is enabled, if a Policy Map containing classification rules (ACL and/or dscp/
ip-precedence rules) is applied to more than one physical interface on the same port pipe, only a single
copy of the policy will be written (only 1 FP entry will be used).
Note that an ACL itself may still require more that a single FP entry, regardless of the number of
interfaces. Refer to IP Access Control Lists, Prefix Lists, and Route-map in the FTOS
Configuration Guide for complete discussion.
default
Reset egress CAM ACL entries to default settings.
l2acl
number
Allocate space for Layer 2 egress ACL.
Range: 1-4 FP blocks
