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).
