<more coming soon>

The Dell hardware will be preloaded with a different version of FTOS. Here are few things we need to do before we load the FTOS version for the project. These include configuring the management interface to your management network specifics. Note that the controller needs to be accessible via the management interface for OpenFlow communication between the controllers and switches. We also need to provide ssh access into the switch. Use the console port (and a terminal emulator) for the configuration below.

#conf
(conf)# interface managementethernet 0/0
(conf-if-ma-0/0)# ip address <ip-addr-of-mgmt-interface>
(conf-if-ma-0/0)# no shutdown
(conf-if-ma-0/0)# exit
(conf)# management route 0.0.0.0/0 <gateway-ip>
(conf)# username <your-username> password <set-a-pwd> privilege 15
(conf)# ip ssh server enable
(conf)# ip ssh password-authentication enable
(conf)# exit
# sh running config

Once the above configuration is complete, the switch should be accessible via ssh. Copy the downloaded FTOS version to the switch using scp from your local machine.

$ scp <path/to/>FTOS-SE-1-0-0-3516.bin <username>@<switch-management-IP-addr>:FTOS-SE-1-0-0-3516.bin

Now login to the switch using ssh to enter the following commands to load the binary you just copied over. First check that you can see the file in the flash.

Upgrade the OS. It takes a few minutes. 

sr101# upgrade system flash://FTOS-SE-1-0-0-3516.bin A:
! .....
 
sr101# reload

Once the upgrade is done, reload the box. You will of course lose your ssh session. But once it is back, login again to configure the OpenFlow instance.
