Configuration Guide Configuring ARP
device receives an ARP update packet from the peer end within the aging time, it stores the entry. If not, it deletes the
entry.
2. If the corresponding ARP entry exists, NUD is not performed.
3. If the MAC address in the existing dynamic ARP entry is updated, the device also performs NUD.
Since this function adds a strict confirmation procedure in the ARP learning process, it affects the efficiency of ARP
learning.
After this function is disabled, NUD is not required for learning and updating ARP entries.

Enabling ARP Trustworthiness Detection
Run the arp trust-monitor enable command in interface configuration mode to enable ARP trustworthiness detection.
This function is disabled by default.
2.3.6 Disabling Dynamic ARP Entry Learning
Working Principle
After dynamic ARP entry learning is disabled on an interface, this interface does not learn dynamic ARP entries.
Related Configuration
Disabling Dynamic ARP Entry Learning
Dynamic ARP entry learning is enabled on interfaces by default.
Run the no arp-learning enable command in interface configuration mode to disable dynamic ARP entry learning.
2.4 Configuration
(Optional) It is used to enable static IP-MAC binding.
Configuring ARP Attributes
(Optional) It is used to specify the ARP timeout, ARP request retransmission interval and
times, maximum number of unresolved ARP entries, maximum number of ARP entries
on an interface, and maximum number of ARP entries on a board.
Configures the ARP timeout.
Configures the ARP request retransmission
interval.
Configures the maximum number of
unresolved ARP entries.
