ARP/ND CACHE TABLE
This part shows ARP table on CSE-H55N. When TCP connection is established or UDP
data communication is performed, the information of IP and MAC address is
automatically stored in the ARP table. This information is held for 1 minute. When 50
seconds is passed, CSE-H55N starts broadcasting the ARP packet again. If there is no
response until the time is 0, the information is removed. If there is response, the time
is updated 60 seconds again.
In IPv6 case, it shows ND cache list. User can check by the ND cache messages. The
messages are as follows.

local address of an opponent in the initial communication.

after it sends Neighbor Solicitation, and receives Neighbor
