Page 5: Openflow 1.0 Support
OpenFlow 1.0 Support OpenFlow (OF) 1.0 [STD-1] is supported on the S4810 and Z9000 platforms. Unsupported OpenFlow Messages The following section provides a list of OpenFlow messages that are not supported. Table 1. Unsupported OpenFlow Messages Message System Response OFPT_SET_CONFIG This message is ignored by the switch. -
Page 7: Exceptions
For OF ports and OF VLANs, the VLAN IDs used for OpenFlow must be unique; the VLAN IDs cannot be used for legacy functionality on the same switch. • Dell Force10 does not recommend using global spanning tree protocol (STP) instances on ports with both legacy VLANs and OF VLANs. •... -
Page 8: L2 Flow Exceptions
Flow priority is ignored for LB flows. • Dell Force10 does not recommend station moves in an LB flow configuration. • Parallel links or paths may not work in an LB flow configuration; Dell Force10 recommends using port channels instead. -
Page 9: Flow Types
Flow Types Dell Force10 switches support four types of flows: • Access Control List (ACL) • • • Learning Bridge (LB) The following sections describe the mandatory match fields, optional match fields, mandatory actions, and optional actions for each flow type. -
Page 10: L2 Flows
Parameter Type Parameters Optional match fields • nw_dst (dst-ip) • All fields other than the ones listed in “Mandatory match fields” and “Optional match fields” must be wildcards. Mandatory actions • You must specify set_dl_src (set src-mac) as the port mac (local mac) for the swtich. - Page 11 Flow Type Max Limit 256 or 512 (depending on ACL content addressable memory [CAM] carving) 48,000 Learning Bridge (LB) 24,000 6,000...

Flow Setup This chapter describes the configuration options required to set up flows. Sample Topology port and In the following sample topology, two OF instances are shown. of-instance 1 has an interface type of VLAN and demonstrates ACL, L2, LB, and L3 demonstrates ACL and L3 flows. -

Page 15: L3 Flows
The entry for dst-mac in the match field and set-src-mac in the action set must use the switch’s port MAC address. All ports on a Dell Force10 switch are associated with the same MAC address, which you can view using the show interface command. -

Page 19: Configuring Acl Cam Carving On S4810
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. -
Page 21: Configuring Acl Cam Carving On Z9000
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. -
Page 23: Openflow Instances
• You can use up to eight OpenFlow instances on a switch; the OF ID range is 1–8. • Only Transmission Control Protocol (TCP) connections are supported on Dell Force10 switches. Transport Layer Security (TLS) connections are not supported. •... -
Page 25: Openflow Interfaces
OpenFlow Interfaces This section describes how you can apply OpenFlow to specific interfaces. • You can use the S4810 and Z9000 as Hybrid switches, allowing both OpenFlow (OF) and legacy functionality simultaneously. • By default, all ports are available for legacy functionality. •... - Page 26 To use both OF ports and OF VLANs, set the interface type to “any.” NOTE: Dell Force10 does not recommend using the interface type “any” unless both OF ports and OF VLANs are required in a single instance. If you use the “any” interface type, the number of ACL flows available to the controller is reduced by half (for example, to 128 of 256 available entries or to 256 of 512 available entries).
