spanning tree close the loop
Hello,
I have a question about adding spanning tree capability for redundancy. I understand basically how it works, but I'd like to save money by only buying one managed switch, and combine it with some unmanaged switches.
Here's my idea:
If my layout is like this: a Host, connected by a single link to M1 (managed switch w/RSTP), and M1 is connected to an unmanged switch, say U1, which is connected to U2, which is connected to U3... to U5. Then U5 is connected back to M1 to close the ring (daisy chain loop).
I'm pretty sure that if either the M1-U1 link is broken, or the M1-U5 link is broken, then the system will recover by activating the backup link.
What I'm not sure about is if a break occurs, say between U3 and U4. Will the M1 switch be smart enough to notice traffic is not getting through, and enable partial forwarding on the backup link?
Thanks,
Randy
