Usage Guidelines

If the no-refresh keyword is not included, ARP requests are automatically triggered for the cleared entries. To avoid this triggering, include the no-refresh keyword. It is required to include the no-refresh keyword, in case the number of ARP entries reaches the system threshold

device# clear arp
