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.
The Switch also supports a floating static route, which means that the user may create an alternative static route with
a different next hop. This secondary next hop device route is considered as a backup static route when the primary
static route is down. If the primary route is lost, the backup route will become active and begin forwarding traffic.
Entries into the Switch's forwarding table can be made using an IP address, subnet mask, and gateway.
