Configuring ACL CAM Carving on S4048–ON,
S4048T-ON and S6010–ON
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, refer to the Content Addressable Memory (CAM) chapter in the Dell Networking OS
Configuration Guide.
NOTE: The commands to allocate CAM space for OpenFlow on the S4048-ON, S4048T-ON and S6010–ON differ from the
commands used for other switches.
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 1000 on the S4048–ON, 2000 on
the S4048T-ON and S6010–ON.
The following is an example OpenFlow :
cam-acl l2acl 2 ipv4acl 2 ipv6acl 0 ipv4qos 0 l2qos 1 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.
NOTE
:
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 .
