Setting the dynamic ARP learning limit for a device
About the dynamic ARP learning limit for a device
A device can dynamically learn ARP entries. To prevent a device from holding too many ARP entries, you can set the maximum number of dynamic ARP entries that the device can learn. When the limit is reached, the device stops ARP learning.
If you set a value lower than the number of existing dynamic ARP entries, the device does not delete the existing entries unless they age out.
