Arp - NETGEAR XS728T ProSAFE Software Administration Manual

Among routes to the same destination, the route with the lowest preference value is the
route entered into the forwarding database. By specifying the preference of a static route,
the user controls whether a static route is more or less preferred. The preference is an
integer value from 1 to 255. You can specify the preference value (sometimes called
"administrative distance") of an individual static route.

To delete a route, select the check box next to the route and click Delete.
The Learned Routes table provides information about the routes the switch already has in its
routing table.

ARP

The Address Resolution Protocol (ARP) associates a Layer 2 MAC address with a Layer 3
IPv4 address. The switch software features both dynamic and manual ARP configuration.
With manual ARP configuration, you can statically add entries to the ARP table.
ARP is a necessary part of the Internet Protocol (IP) and is used to translate an IP address to
a media (MAC) address, defined by a local area network (LAN) such as Ethernet. A station
needing to send an IP packet must learn the MAC address of the IP destination, or of the next
hop router, if the destination is not on the same subnet. Learning is achieved by broadcasting
an ARP request packet, to which the intended recipient responds with a unicast ARP reply
containing its MAC address. Once learned, the MAC address is used in the destination
address field of the Layer 2 header prepended to the IP packet.

Description
Indicates whether the learned route is a static or default route.
The IP route prefix for the destination.
Also referred to as the subnet/network mask, this field indicates the portion
of the IP interface address that identifies the attached network.
This field tells which protocol created the specified route. The possibilities
are the following:
• Local
• Static
The outgoing router interface to use when forwarding traffic to the
destination.
The outgoing router IP address to use when forwarding traffic to the next
router (if any) in the path towards the destination. The next router is always
one of the adjacent neighbors or the IP address of the local interface for a
directly attached network.
The preference value for the configured next hop.
