Hi,
I have about 18 C3548 switches with UTP cross-over as a redundant link to
the core C6009 switches (1 unit) and the production link of LX & SX GBIC.
When the production link is in operation, all the GBIC ports is in
forwarding
state. However when I attach the redundant UTP cable at 1 C3548 to the
another
C3548 (cascade), I wonder why they are still in forwarding state. Here's a
basic
layout.
C3548 \ / C3548
(utp) | \ / | (utp)
C3548 ---- C6009 ----- C3548
(utp) | / \ | (utp)
C3548 / \ C3548
How do I set the cascading port (as a redundant link) into blocking state?
Regards,
Ryan
