Operating Notes
■ TC refers to a Topology Change detected on the given port. Note the following details:
TC Detected counter shows when a port identifies a topology change (increments when
•
the particular non-Edge port goes into forwarding). For RSTP and MSTP, this would be
due to the switch's link going to forwarding.
TC Flag Transmitted counter shows the number of TC notifications sent out of the port.
•
This refers to propagating a topology change that occurred on another port (that is, a
TC Detected increment) or to propagating a topology change received on another port
(that is, TC Flag Received).
