Connection to Controller

To view the currently configured controllers users can enter show openflow controller command.  This will only list the configured controllers and not their status.

SSH@brocade1.sdn-test#show openflow controller

To see the status of each controller the show openflow command lists the currently configured controllers and a list of hybrid and non-hybrid openflow interfaces and the matches supported.

"SSH@brocade2.sdn-test#conf t"

2.) remove the old controller

"no openflow controller ip-address <CURRENT_IP_ADDRESS> no-ssl port <PORT>"

3.) add new controller

"openflow controller ip-address <NEW_IP_ADDRESS> no-ssl port <PORT>"

4.) run "write mem" if you want to save the changes on reboot
