Adjusting Your CAM Profile
Although adjusting your CAM profile is not a mandatory step, if you plan to implement IPv6 ACLs, Dell
Networking recommends that you adjust your CAM settings.
The CAM space is allotted in FP blocks. The total space allocated must equal 13 FP blocks. There are 16
FP blocks, but the System Flow requires three blocks that cannot be reallocated.
You must enter the ipv6acl allocation as a factor of 2 (2, 4, 6, 8, 10). All other profile allocations can use
either even or odd-numbered ranges.
The default option sets the CAM Profile as follows:
• L3 ACL (ipv4acl): 6
• L2 ACL(l2acl): 5
• IPv6 L3 ACL (ipv6acl): 0
• L3 QoS (ipv4qos): 1
• L2 QoS (l2qos): 1
To have the changes take effect, save the new CAM settings to the startup-config (write-mem or copy
run start
) then reload the system for the new settings.
• Allocate space for IPV6 ACLs. Enter the CAM profile name then the allocated amount.
CONFIGURATION mode
cam-acl { ipv6acl }
When not selecting the default option, enter all of the profiles listed and a range for each.
The total space allocated must equal 13.
The ipv6acl range must be a factor of 2.
• Show the current CAM settings.
EXEC mode or EXEC Privilege mode
show cam-acl
• Provides information on FP groups allocated for the egress acl.
CONFIGURATION mode
show cam-acl-egress
Allocate at least one group for L2ACL and IPv4 ACL.
The total number of groups is 4.
Assigning an IPv6 Address to an Interface
Essentially, IPv6 is enabled on a switch simply by assigning IPv6 addresses to individual router interfaces.
You can use IPv6 and IPv4 together on a system, but be sure to differentiate that usage carefully. To
assign an IPv6 address to an interface, use the ipv6 address command.
