The system only forwards packets that satisfy the following restrictions:
• The destination MAC address must be a broadcast address.
• The destination IP address must be an all-one broadcast.
• The packets are IPv4 UDP packets.
• The IP TTL value must be greater than or equal to 2.

IPv4 Static/Default Route
This window is used to display and configure the IPv4 static and default route settings. The Switch supports static
routing for IPv4 formatted addressing. Users can create up to 512 static route entries for IPv4. For IPv4 static routes,
once a static route has been set, the Switch will send an ARP request packet to the next hop router that has been set
by the user. Once an ARP response has been retrieved by the Switch from that next hop, the route becomes enabled.
However, if the ARP entry already exists, an ARP request will not be sent.
