The arp detect-times command sets the aging probe times of dynamic Address Resolution Protocol (ARP) entries.
The undo arp detect-times command restores the default setting.
By default, the aging probe times of dynamic ARP entries is 3.

Usage Scenario
To set the aging probe times of dynamic ARP entries, run the arp detect-times detect-times command. This reduces address resolution errors. Before aging a dynamic ARP entry, the system sends probe messages. If the system fails to receive any response for a specified number of times, the system deletes the ARP entry.
Precautions
If times-value is set to 0, dynamic ARP entries are aged directly without being probed. You are advised not to set times-value to 0. Otherwise, ARP entry update is affected, which causes service traffic forwarding failures.
