Hi,
About the ARP aging time. To reduce the number of ARP requests on the network side, you can set it to a longer period.
The actual aging time is 0.5–1.5 times of the configured aging time. If the configured value is 30s, the actual aging time is a random value within the range of 15–45s. Set the aging time according to the actual network conditions.
Value range: 5–1440s. Default value: 30s
Thanks.
