ARP Troubleshooting

If ping from the switch to directly connected network devices fails, the following can

be used to check the possible cause and create a solution.

 Check whether the corresponding ARP has been learned by the switch.

 If ARP has not been learned, then enabled ARP debugging information and view

the sending/receiving condition of ARP packets.

 Defective cable is a common cause of ARP problems and may disable ARP

learning.

station movement

3.6.1

Introduction to l3 station movement

When arp/nd switch over the port in normal condition, learn the port information of

arp/nd entry again according to arp/nd packets. If PC or other network nodes switch over

the port, non-security switchover (ARP packets are not sent or received) does not process

to learn again. New l3 station movement is used to satisfy arp/nd switchover in specific

condition. When MAC switch over the port, it is considered to be security switchover, any

network packets (src mac is the network node that process switchover) received from new

port spring arp/nd switchover, learn arp/nd to new port.
