Ingress ARP Packet Priority

You can configure the priority of ingress ARP packets to an optimum value based on network configuration and traffic volume. Ingress ARP packets have a default priority value of 4. At the default priority value, ingress ARP packets may be dropped because of high traffic volume or non-ARP packets with higher priority values. This can cause devices to become unreachable. If the ingress ARP packets are set to a higher priority than the default priority value, a high volume of ARP traffic may lead to control traffic being dropped. This may cause traffic loops in the network.
