Changing Controller

To change the openflow controller complete the following steps

1.) choose iscli mode

"Select Command Line Interface mode (bladeos-cli/iscli): iscli"

2.) type enable

"nec>enable"

3.) type the show run command to see the current controller configuration

"nec#show run"

which will output something like the following...

"

Current configuration:

!

version "7.4.1.1"

switch-type "NEC PF5820"

!

!

.......

openflow instance 1

enable

buffer

echo-request-interval 1000

emergency

        controller 1 address 1.2.3.4

member 20-25,40,42,60

!

openflow instance 2

enable

controller 2 address 5.6.7.8

!

......."

The important bit being contained in the "openflow instance 1" section.

4.) run configure terminal command

"nec#configure terminal"

5.) type the openflow instance to edit

"nec(config)#openflow instance 1"

6.) Finally set the new controller address

"nec(config-openflow-instance)#controller 1 address <NEW_IP_ADDRESS>"

7.) you will more than likely then have to run the "write mem" command and then the "reload" command for the changes to take affect
