Configuring Distributed IP ARP Mode

The distributed IP ARP feature is available only on BlackDiamond X8 and 8800 series switches. The distributed IP ARP feature provides higher IP ARP scaling by distributing IP ARP forwarding information to only the I/O module to which each IP host is connected. This feature is off by default to match the operation in ExtremeXOS releases prior to 12.5. When this feature is off, complete IP ARP information for all destinations is stored on all modules, reducing the available space for unique destinations.
