From software version 5.4.9-2.1 onwards, the x530, x530L Series support version 1.3 of Openflow Specification. This means that the x530/x530L Series OpenFlow switches are able to match on any of the following ...

The Brocade ICX 6610 enables SDN by supporting the OpenFlow 1.3 protocol, which allows communication between an OpenFlow controller and an OpenFlow-enabled switch. Using this approach, organizations can control their networks programmatically, transforming the network into a platform for
Since OpenFlow 1.2, the number of match fields has kept increasing. Also, the specification keeps getting complicated as it get extended into different use-cases. This phenomena is referred to as the “match fields’ explosion”. Instead of changing the specification, some people argue that the future switch should support flexibleFile Size: 728KB
