Dell EMC SmartFabric OS10 User Guide Release 10.5.0

When you convert the switch from Normal mode to OpenFlow mode, the switch retains the management, interface, and AAA settings.

The following lists the minimum configuration you need to establish a connection between the OpenFlow controller and a logical switch instance:

1. Enter the OPENFLOW configuration mode.

   OS10# configure terminal
   OS10 (config)# openflow
   OS10 (config-openflow)#

2. Enable the OpenFlow-only mode.

   OS10 (config-openflow)# mode openflow-only

   Reload the switch. Enter yes to enable OpenFlow-only mode.

   NOTE When the switch starts up in OpenFlow mode, it disables all Layer 2 (L2) and Layer 3 (L3) protocols. Many CLI commands are not available in OpenFlow-only mode. For a list of available commands in OpenFlow-only mode, see OpenFlow-only mode commands.
3. Configure a logical switch instance.
   1. Option 1; for Out of Band (OOB) management:
      1. Configure an IP address for the management port. Ensure that there is IP connectivity between the switch and the controller.

         OS10# configure terminal
         OS10 (config)# interface management 1/1/1
         OS10 (conf-if-ma-1/1/1)# ip address 11.1.1.1/24
         OS10 (conf-if-ma-1/1/1)# no shutdown
         OS10 (conf-if-ma-1/1/1)# exit
         

      2. Configure the logical switch instance, of-switch-1.

         OS10# configure terminal
         OS10 (config)# openflow
         OS10 (config-openflow)# switch of-switch-1 

   2. Option 2; for in-band management:
      1. Configure one of the front-panel ports as the management port.

         OS10# configure terminal
         OS10 (config)# openflow
         OS10 (config-openflow)# in-band-mgmt interface ethernet 1/1/1
         OS10 (config-openflow)# 
         

      2. Configure an IPv4 address on the front-panel management port.

         OS10# configure terminal
         OS10 (config)# interface ethernet 1/1/1
         OS10 (conf-if-eth1/1/1)# ip address 11.1.1.1/24
         OS10 (conf-if-eth1/1/1)# no shutdown
         

      3. Configure the logical switch instance, of-switch-1.

         OS10# configure terminal
         OS10 (config)# openflow
         OS10 (config-openflow)# switch of-switch-1

4. Configure one or more OpenFlow controllers with either IPv4 or IPv6 addresses to establish a connection with the logical switch instance. You can configure up to eight OpenFlow controllers.

   OS10 (config-openflow-switch)# controller ipv4 ip-address port port-id
   OS10 (config-openflow-switch)# controller ipv6 ipv6-address port port-id

   OS10 (config-openflow-switch)# controller ipv4 10.1.1.1 port 6633
   OS10 (config-openflow-switch)# controller ipv4 10.1.1.8 port 6633
   OS10 (config-openflow-switch)# controller ipv4 10.1.1.12 port 6633
   OS10 (config-openflow-switch)# controller ipv4 10.1.2.17 port 6633
   OS10 (config-openflow-switch)# controller ipv4 10.1.23.12 port 6633
   OS10 (config-openflow-switch)# controller ipv4 10.1.99.121 port 6633
   OS10 (config-openflow-switch)# controller ipv6 2025::1 port 6633
   OS10 (config-openflow-switch)# controller ipv6 2025::12 port 6633

   where IP or IPv6 address is of the controller and port 6633 is for OpenFlow communication.

5. Enter the no shutdown command to enable the logical switch instance.

   OS10 (config-openflow-switch) no shutdown
