Error Messages and Recovery Procedures
Error Message RTD-1-LINK_FLAP [chars] link down/up [dec] times per min
Explanation This message means that an excessive number of link down-up events has been noticed
on this interface: [chars] is the interface, and [dec] is the number of times the link goes up and down.
This might be the result of reconfiguring the port, or it might mean a faulty device at the other end
of the connection.
Recommended Action If someone is reconfiguring the interface or device at the other side of the
interface, ignore this message. However, if no one is manipulating the interface or device at the other
end of the interface, it is likely that the Ethernet transceiver at one end of the link is faulty and should
be replaced.
