Setting
Tab „CIST“ Port configuration and information
on the global MSTI (IST) and the
CST.
STP active Here you can switch Spanning Tree
on or off for this port. If Spanning
Tree is activated globally and
switched off at one port, this port
does not send STP-BPDUs and
drops any STP-BPDUs received.
Note: If you want to use other
layer 2 redundancy protocols such
as HIPER-Ring or Ring/Network
coupling in parallel with Spanning
Tree, make sure you switch off the
ports participating in these protocols
in this dialog for Spanning Tree.
Otherwise the redundancy can fail
or loops can result.

Port path costs Enter the path costs with regard to
the global MSTI (IST) to indicate
preference for redundant paths. If
the value is 0, the Switch
automatically calculates the path
costs for the global MSTI (IST)
depending on the transmission rate.

of the port ID.
