ARP Table / ND Cache Table
This part shows ARP table on CSW-H85K. When TCP connection is established or UDP
data communication is performed, the information of IP and MAC address is
automatically registered in the table. This information lasts for 1 minute so when 50
seconds has passed, CSW-H85K starts broadcasting the ARP packet in every second.
If there is no response until the time is 0, the information is removed. Otherwise, the
time is updated 60 seconds again.
In IPv6 case, it shows ND cache table. User can check by the ND cache messages. The
messages are as follows.

after it sends Neighbor Solicitation, and receives Neighbor

response to Neighbor Solicitation. In this case, CSW-H85K
will not be able to communicate with the device.

CSW-H85K will resend the request message to the device in
DELAY state. CSW-H85K will keep sending Neighbor
Solicitation until it replies.
