Hello David,
here is what the Error Message Decoder has to say...
1. %RTD-1-ADDR_FLAP [chars] relearning [dec] addrs per min
Normally, MAC addresses are learned once on a port.Occasionally, when a
switched network reconfigures, due to either manualor STP reconfiguration,
addresses learned on one port are relearned on adifferent port. Howeve r, if
there is a port anywhere in the switched domainthat is looped back to
itself, addresses will jump back and forth betweenthe real port and the port
that is in the path to the looped back port. Inthis message, [chars] is the
interface, and [dec] is th e number of addressesbeing learnt.
Recommended Action: Determine the real path (port) to the MAC address. Use
the debug ethernet-controller addr command to see the alternate path-port on
which the address is being learned.Go to the switch attached to that port.
Note that the show cdp neighbors command is useful in determining the next
switch. Repeat this procedureuntil the port is found that is receiving what
it is transmitting, and removethat port from the network.
Regards,
Georg
