i checked my configuration now with ip san and it's connected with my 3750x 10G nic, there's no "spanning-tree portfast" command on it. I don't remember if I have notes not to put it. Just having error now when it's disconnect and reconnect and since there's no "spanning-tree portfast", it will be slow to reconnect therefore got an alert at night.
Do I need it and can i put it without any problem?
