G8264 Application Guide for ENOS 8.4
When OpenFlow is enabled, all OpenFlow instance member ports become
OpenFlow ports. OpenFlow ports have the following characteristics:
 Learning is turned off.
Flood blocking is turned on.

 Spanning Tree Protocol (STP) is disabled.
The switch communicates with OpenFlow controllers through controller
management ports or through dedicated out‐of‐band management ports on the
switch. All OpenFlow ports, except controller management ports, must be
members of VLAN 1. Controller management ports can be members of any VLAN
except VLAN 1.
Note: When the switch operates in the default boot profile, we recommend that you
use a non‐OpenFlow port to connect the switch with the controller. Use the
following command to view port information:
RS G8264(config)# show interface information
For each OpenFlow instance, when you configure the controller IP address and
port, the switch establishes a TCP connection with the controller for flow control
and management. See Step 3 on page
controllers per instance. The default controller port is 6633 and is reachable via any
in‐band port configured as management port or through dedicated out‐of‐band
management port (MGT). The controller management ports must not be members
of an OpenFlow instance. You can use a controller to manage and control multiple
instances.
Use the following command to configure a data port as a controller management
port (available only in OpenFlow boot profile):
RS G8264(config)# openflow mgmtport <port number>
Note: In default boot profile, when you disable OpenFlow, the OpenFlow ports
become legacy switch ports and are added to the default VLAN 1.
You can configure a port as an OpenFlow edge port. Edge ports are connected to
either non‐OpenFlow switches or servers. OpenFlow edge ports have the
following characteristics:
 Flood blocking is turned on.
 MAC learning is turned on.
Use the following command to configure a port as an edge port:
RS G8264(config)# openflow instance <instance ID>
RS G8264(config­openflow­instance)# edgeport <port number>
Note: Edge ports are not OpenFlow standard ports. You must configure edge ports
only if the controller supports it.
