Configuring ACL CAM Carving on Z9000

Dell Networking switches can operate in Hybrid mode, which enables OpenFlow and legacy functionality on the same

switch. By default, access control list content addressable memory (ACL CAM) space is not allocated for OpenFlow. To

enable OpenFlow, reserve CAM space for OpenFlow using the following commands. For more information on CAM, refer

to the

Content Addressable Memory (CAM)

chapter in the

FTOS Configuration Guide

NOTE: The commands to allocate CAM space for OpenFlow on the Z9000 differ from the commands used for the

S4810, S4820T, and MXL switch.

Enter a value for cam-acl.

Select one of the following values for cam-acl:

– 0 (default): No space is allocated for OpenFlow. Change this value to four or eight to enable OpenFlow.

– 4: Allocates space for up to 242 flow entries (14 entries are reserved for internal purposes from the 256

available flows, leaving 242 entries for use by OpenFlow).

– 8: Allocates space for up to 498 flow entries (14 entries are reserved for internal purposes from the 512

available flows, leaving 498 entries for use by OpenFlow).

The following sample Z9000 configuration reserves 512 entries for OpenFlow:

FTOS(conf)# cam-acl l2acl 2 ipv4acl 2 ipv6acl 0 ipv4qos 4 l2qos 1 l2pt 0

ipmacacl 0 vman-qos 0 ecfmacl 0 openflow 4

NOTE: For Z9000, the cam-acl-vlan value is set to 1 (enabled) by default; no additional configuration is

required.

NOTE: Reboot the switch after changing the cam-acl values. If you do not reboot the switch, the configuration

changes do not take effect.

To upgrade any configuration changes that have changed the NVRAM content, if you enable BMP 3.0, use the

reload conditional nvram-cfg-change command to perform a reload on the chassis .
