Configuring ACL CAM Carving on S4810

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 S4810 differ from the commands used for Z9000.

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 S4810 configuration reserves 512 entries for OpenFlow:

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

ipmacacl 0 vman-qos 0 ecfmacl 0 openflow 8 fcoeacl 0 iscsioptacl 0

Enter a value for cam-acl-vlan.

Select one of the following values for cam-acl-vlan:

–

0 (default): No space is allocated for OpenFlow. You must change this value to 1 to enable OpenFlow.

–

1: Enables OpenFlow functionality.

The following sample configuration shows a value of 1 for cam-acl-vlan:

FTOS(conf)#cam-acl-vlan vlanopenflow 1 vlaniscsi 1

NOTE: You must reboot the switch after changing the cam-acl and cam-vlan-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.
