Enable so-called sticky ARP mode for the interface. | |||||||||||
If this option is enabled on the given interface, any resolved address is | |||||||||||
marked as a static one and never expires. This may be used to increase | |||||||||||
security of the network by preventing ARP spoofing or to reduce latency for | |||||||||||
high-performance Ethernet networks where the time needed for ARP resolution is | |||||||||||
too high. Please note that similar feature is also provided for bridges. See | |||||||||||
