Figure 3.11: System Setting

ARL aging time ( 0~ 1048575)

Aging time is counted from the last time that the switch saw the MAC

address. The default value is 300 seconds. That means if EKI-6538

doesn’t receive the packet from the specific MAC address for 300 sec-

onds, this MAC address will be removed from ARL table. EKI-6538 will

broadcast the following packets from this MAC address, learn and record

the behavior again until rebuild it into ARL table.

If you disable the ARL aging function, EKI-6538 will not record or

remember any MAC address while its MAC address table capacity is full.

Packets coming from the MAC address outside the existed MAC address

table would be broadcast to all ports.
