Allocating CAM for Egress ACLs on the Port Extender
To allocate Content Addressable Memory (CAM) for egress ACLs on the port extender.
You can re-allocate memory space for egress ACLs on the port extender by using the cam-acl-egress-pe command in
CONFIGURATION mode.
The default CAM allocation settings for the three egress ACL and QoS regions on an switch are
• L2 ACL(l2acl): 1
• L3 ACL (ipv4acl): 1
• IPv6 L3 ACL (ipv6acl): 2
The total egress CAM ACL space must equal 4 memory blocks. The ranges of supported FP memory blocks are: You must
allocate at least one block of memory to the L2ACL and IPv4 ACL regions.
• L2 ACL(l2acl): 1 to 3
• L3 ACL (ipv4acl): 0 to 2
• IPv6 L3 ACL (ipv6acl): 0 to 4
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.
1 Enter a CAM allocation action to perform on egress 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.
CONFIGURATION mode
cam-acl-pe [default| l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number
ipmacacl number ipv4pbr number]
NOTE: Selecting default resets the CAM entries to the default settings. Select l2acl to re-allocate memory space for
egress ACL and QoS regions
2 Verify the details of CAM ACL egress profiles configured globally on the PE. It does not display CAM ACL egress profiles for
each PE. The new settings will be written to CAM on the next reload.
EXEC and EXEC Privilege mode
show cam-acl-egress-pe
3 Reload the system.
EXEC Privilege mode
reload
Examples of Allocating CAM for Egress ACLs on the Port Extender
The following example displays the current CAM ACL settings for each egress region and configures the egress CAM settings.
Dell# show cam-acl-egress-pe
-- Port extender Egress Cam ACL --
Current Settings(in block sizes)
1 block = 256 entries
L2Acl : 1
Ipv4Acl : 1
Ipv6Acl : 2
Dell(conf)#cam-acl-egress-pe l2acl 2 ipv4acl 2 ipv6acl 0
The following example displays the running configuration for the configured CAM ACLs.
Dell(conf)#do show running-config | grep cam-acl
cam-acl l2acl 3 ipv4acl 4 ipv6acl 0 ipv4qos 2 l2qos 1 l2pt 0 ipmacacl 0 vman-qos 0 ecfmacl 0
