Configuring ACL CAM Carving on Z9000
Dell Force10 switches can operate in Hybrid mode, which enables OpenFlow and legacy functionality on the same
switch. By default, ACL CAM space is not allocated for OpenFlow. To enable OpenFlow, you must reserve CAM space
for OpenFlow using the following commands.
NOTE: The commands to allocate CAM space for OpenFlow on Z9000 differ from the commands used for S4810.
Enter a value for cam-acl.
Select one of the following values for cam-acl:
– 0 (default): No space is allocated for OpenFlow. You must 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 0 l2qos 1 l2pt 0
ipmacacl 0 vman-qos 0 ecfmacl 0
openflow 8
NOTE: For Z9000, the cam-acl-vlan value is set to 1 (enabled) by default; no additional configuration is
required.
NOTE: You must reboot the switch after changing the cam-acl values. If you do not reboot the switch, the
configuration changes do not take effect.
If BMP 3.0 is enabled, use the command reload conditional nvram-cfg-change to perform a reload
on the chassis to upgrade any configuration changes that have changed the NVRAM content.
