I'm disturbed by this BNA status of the same dashed line (yellow/gray) and the final status (forbidden access sign)
what I did:
I had 4 ISL links from my bladechassis Switch towards my Brocade 6505 switch infra.
My initial reponse :
I persistently disabled 2 ports (on both sides) ; double clcnking on the link in beween both switches, I now have a status indicating I have 2 missing links and what these links used to be.
I have no trunking mode enabled either.
I tried to rename the port to something else
My 2nd attempt : I checked the port type , I reconfigured the ports on both sides to F-port (instead of E+F) , still clicking in the toplogy view on the link between both switches, it still suggests that I have 2 missing connnections
My 3rd attempt : In advanced mode I went to disable trunk mode on these ports (on both sides) , but still BNA keeps displaying in the same manner.
What to do with BNA to make it understand that what it had is no longer of any concern ?
What is required for its status to change ?
