We are adding HP BladeFrame Switches to our environment via ISLs to our Core switches.

When you pull up FM, go to the "Physical Attributes" frame and select ISLs, we notice that

the BFS shows up as the "From Switch"  while the Core Switch shows up as the "To Switch"

but then the next switch shows up with the core switch as the "From switch" and the BFS as the

"to switch". 

Is this a timing issue when the ports are initializing or is there a better reason?

Thanks
