Usage Guidelines The Flaps column in the display shows how many changes to the state within the specified time interval
will cause an error to be detected and a port to be disabled. For example, the display shows that an error
will be assumed and the port shut down if three Dynamic Trunking Protocol (DTP)-state (port mode
access/trunk) or Port Aggregation Protocol (PAgP) flap changes occur during a 30-second interval, or if
5 link-state (link up/down) changes occur during a 10-second interval.
