1612 OpenFlow
The OpenFlow 1.0 standard supports a single-table data forwarding path.
Dell Networking switches support Open Vswitch proprietary extensions to
enable the OpenFlow controller access to multiple forwarding tables.
The OpenFlow 1.3 standard enables a multi-table data forwarding path. Dell
Networking switches, however, support a single-table OpenFlow 1.3 data
forwarding path.
The Dell Networking OpenFlow feature has the following major functions:
1
Enabling Dell Networking OpenFlow Hybrid.
2 Deploying OpenFlow Configuration.
3 Interacting with the OpenFlow Controllers.
4 Deploying OpenFlow Controller Flows.
5 Collecting Port and Queue Status and Statistics.
6 Supporting OpenFlow Controller Group tables
Enable Dell Networking OpenFlow Hybrid
The OpenFlow feature can be enabled and disabled by the network
administrator. Although Dell Networking OpenFlow Hybrid may be
administratively enabled, it is not operational until the switch has an IP
address.
The OpenFlow feature can be administratively disabled at any time. After
administratively disabling the feature, the network administrator must wait
until the OpenFlow Feature is operationally disabled before re-enabling the
feature.
The administrator can allow the switch to automatically assign an IP address
to OpenFlow or to specifically select which address should be used. The
administrator can also direct the OpenFlow feature to always use the out-of-
band interface.
If the address is assigned automatically and the interface with the assigned
address goes down, the switch selects another active interface if one is
available. Dell Networking OpenFlow Hybrid becomes operationally disabled
and re-enabled when a new IP address is selected. If the address is assigned
statically, the OpenFlow feature comes up only when a switch interface with
the matching IP address becomes active.
