Content Addressable Memory | 289To change the CAM profile on the entire system:CAM AllocationUser Configurable CAM Allocations is available on platforms: c sAllocate space for IPV4 ACLs and QoS regions, and IPv6 6 ACLs and QoS regions on the C-Series andS-Series by using the cam-acl command in CONFIGURATION mode.The CAM space is allotted in FP blocks. The total space allocated must equal 13 FP blocks. The defaultCAM Allocation settings on a C-Series system are:• L3 ACL (ipv4acl): 5• L2 ACL(l2acl) : 6• IPv6 L3 ACL (ipv6acl): 0• L3 QoS (ipv4qos): 1• L2 QoS (l2qos): 1• L2PT (l2pt): 0• MAC ACLs (ipmacacl): 0• ECFMACL (ecfmacl): 0• VMAN QoS (vman-qos): 0• VMAN Dual QoS (vman-dual-qos): 0Step Task Command Syntax Command Mode1 Select a CAM profile. cam-profile profile microcodemicrocode CONFIGURATIONNote: If selecting a cam-profile for VRF (cam-profile ipv4-vrf or ipv4-v6-vrf), implement the commandin the CONFIGURATION mode only.

These ACL are not created through CLI,but rather are system generated from the DHCP snooping table. Whenever a new DHCP client isassigned an IP, and ip dhcp snooping source-address-validation ipmac is configured on the interfaceconnected to the client, a single ACL is installed on the interface to permit (only) the source IP and sourceMAC pair.
