Hi All, Although I have been able to run a controller with this switch, there are some things in the release notes that I am confused about:
"The OpenFlow controller traffic can not be “in-band”. It can not transit on a VLAN managed by OpenFlow, and must transit on a VLAN not managed by OpenFlow. On the other hand, the controller traffic and OpenFlow traffic can transit on the same port, as long as they use different VLANs. The VLAN chosen for the controller traffic depends entirely on the IP address of the controller, and no specific configuration is needed. For this reason, the switch should have a proper IP configuration, and the controller address must be part of a subnet that is not on an OpenFlow VLAN." Can anyone explain to me: What does OpenFlow traffic refer to here (Is it referring to traffic between nodes managed by controller?) and why do we need a separate VLAN for the controller and OpenFlow traffic? Also, why is the choice of controller's VLAN dependent on the IP address of controller? Thanks, Salman
