The following table lists the per-flow counters available:

Considerations and limitations

Brocade devices support version 1.0.0 of the OpenFlow protocol. Consider the following points

when you configure OpenFlow on devices.

• OpenFlow must be enabled globally on the device before you can enable interfaces for

OpenFlow.

• You must explicitly enable or disable OpenFlow on each interface using the CLI commands.

You cannot use a range of ports to enable OpenFlow on them.
