Usage guidelines
Each dynamic ARP entry in the ARP table has a limited lifetime, called an aging timer. The aging
timer of a dynamic ARP entry is reset each time the dynamic ARP entry is updated. Dynamic ARP
entries that are not updated before their aging timers expire are deleted from the ARP table.
Set the aging timer for dynamic ARP entries as needed. For example, when you configure proxy
ARP, set a short aging time so that invalid dynamic ARP entries can be deleted in time.
Examples
# Set the aging timer for dynamic ARP entries to 10 minutes.
