Ip Helper Address; Ipv4 Static/Default Route - D-Link DXS-3600 Series Reference Manual

DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch Web UI Reference Guide

IP Helper Address

This window is used to add or remove a target address for the forwarding of UDP broadcast packets. This
feature takes effect only when the received interface has an IP address assigned.
The system only forwards the packet that satisfies the following restriction.
•
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 view and configure the IPv4 static and default route settings. The switch supports
static routing for IPv4 formatted addressing. Users can create up to 1024 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 to a different next hop. This secondary next hop device route is considered as a backup static
route for when the primary static route is down. If the primary route is lost, the backup route will uplink and
its status will become active.
Entries into the switch's forwarding table can be made using both an IP address subnet mask and a
gateway.
