I should be clear when i say trunk. I am talking about HPs trunk terminology where 2 switch ports act as one port. I know it might be something different in the cisco world.
I am not familar with RSTP.
I believe my switch is current using MSTP. That is what it shows when i do a "show spanning-tree config" in my procurve.
It also says STP Enabled: NO
This tells me that spanning tree isnt even on.....
Either way....STP is for preventing loops. If this is the case and i had 2 switches for redundancy, in theory isnt it only going to use one path until it fails at which time the other path becomes active?
If this is the case i can see why the previous person who set this up added the TRK ports on the switch. IT provides a single logical port across 2 physical ports. STP doesnt stumble over it during a port failure....and also....it appears to offer a bit of load balancing across switch ports.
I guess i am still back to my original question. How do i introduce a second switch and make it redundant.
Not sure if there is a way to TRK a single port from 2 different physical switches. That would do the trick.....however that seems impossible.
