OpenFlow 1653
OpenFlow Hybrid
The operation of the OpenFlow switch in a network largely depends on the
functionality of the OpenFlow controller. The OpenFlow feature is a powerful
tool that enables the OpenFlow controller to forward packets in the network
without regard to the Layer-2 forwarding database and the IPv4 routing
tables.
Refer to the OpenFlow Controller documentation to understand how the
switch behaves in the customer network.
The one legacy networking rule the switch enforces is that the switch does not
forward packets over ports that are in spanning-tree blocking state for the
egress VLAN, even if the OpenFlow Controller has configured a rule to do so.
Example Configuration
This example configures the switch to operate with OpenFlow version 1.3 and
to connect to the controller at IP address 1.2.3.4 on port 3435 with no
security.
console(config)#vlan 10
console(config-vlan10)#interface vlan 10
console(config-if-vlan10)#ip address 1.2.3.1 255.255.0.0
console(config-if-vlan10)#interface gi1/0/1
console(config-if-Gi1/0/1)#switchport mode access
console(config-if-Gi1/0/1)#switchport access vlan 10
console(config-if-Gi1/0/1)#exit
console(config)#openflow
WARNING! OpenFlow does not operate on stack members. Enable
OpenFlow on stand-alone switches only.
