The system output looks like this:
switch1# debug fspf all
Jan 5 00:39:31 fspf: FC2 packet received for non existent region 0 in VSAN 1 -----1
Jan 5 00:39:33 fspf: FC2 packet received for non existent region 0 in VSAN 1
Jan 5 00:39:45 fspf: Interface fc1/1 in VSAN 1 : Event INACTIVITY , State change INIT ->

switch1# show run
fspf config vsan 1
region 1
