Configuring ACL CAM Carving on the C9000

Series

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. The amount of CAM space that you allocate for OpenFlow determines the number of

available ACL entries. For more information on CAM, see the Content Addressable Memory (CAM) chapter in the Dell Networking C9000

Configuration Guide and the Dell Networking C9000 series Command Line Reference Guide.

NOTE: The commands to allocate CAM space for OpenFlow on the C9000 Series.

1 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.

• If OpenFlow interface-type is PORT or VLAN, maximum number of flows that you can install is 1004.

• If OpenFlow interface-type is ANY, the maximum number of flows that you can install is 502.

The following example OpenFlow:

Dell(conf)# cam-acl l2acl 1 ipv4acl 0 ipv6acl 0 ipv4qos 1 l2qos 2 l2pt 0 ipmacacl 0 vman-qos

0 ecfmacl 0 openflow 8

2 Enter the value for cam-acl-vlan

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

• 0 (default): No space is allocated for OpenFlow. Change this value to one to enable OpenFlow.

• 1: Enables OpenFlow.

The following example shows a value of one allocated for cam-acl-vlan:

Dell(conf)# cam-acl-vlan vlanopenflow 1 vlaniscsi 1 vlanaclopt 0

3 Reboot the switch after changing the cam-acl and cam-acl-vlan values. If you do not reboot the switch, the configuration

changes do not take effect.
