Administrator Guide

The default CAM allocation settings for ingress ACL and QoS regions are the following:
L2Acl : 5
Ipv4Acl : 4
Ipv6Acl : 0
Ipv4Qos : 2
L2Qos : 1
L2PT : 0
IpMacAcl : 0
VmanQos : 0
EcfmAcl : 0
FcoeAcl : 0
iscsiOptAcl : 0
ipv4pbr : 0
vrfv4Acl : 0
Openflow : 0
fedgovacl : 0
nlbclusteracl: 0
Select the 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, and Policy-based Routing (PBR). Save the new CAM settings to the startup-cong (write-
memor copy run start) then reload the system for the new settings to take eect. The total amount of space allowed is 12 FP Blocks.
System ow requires four blocks; these blocks cannot be reallocated.
The ipv4acl prole range is from 0 to 8. Ranges for the CAM proles are from 1 to 10, except for the ipv6acl prole which is from 0 to
4. The ipv6acl allocation must be a factor of 2 (2, 4). If allocation values are not entered for the CAM regions, the value is 0.
1 Enter a CAM allocation action to perform on ingress ACLs. Enter the number of FP blocks for each region. Separate each keyword and
number with a blank space. The total CAM space allocated must equal 12. When conguring space foripv6acl, the total number of
Blocks must be in multiples of 2.
CONFIGURATION mode
cam-acl-pe [default| l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number

NOTE
: Selecting default resets the CAM entries to the default settings. Select l2acl to re-allocate memory space for
ingress ACL and QoS regions.
2 Verify the new settings that will be written to CAM on the next reload. The CAM ACL ingress proles are congured globally on the
PE. The show cam-acl-pe command does not display CAM ACL ingress proles for each PE. The new settings will be written to
CAM on the next reload
EXEC and EXEC Privilege mode
show cam-acl-pe
3 Reload the system.
