21.5.3 ARP Troubleshooting

If ping from the switch to directly connected net work devices fails, the following can be used to check the
possible cause and create a solution.
 Check whether the corresponding A RP has been learned by the Chassis Switch.
 If A RP has not been learned, then enabled ARP debugging information and view the sending/rec eiving
condition of A RP packets.
 Defective cable is a common cause of ARP problems and may disable A RP learning.
