Table 4-23. Ethernet Management Options (2 of 2)

Default Gateway Address

Possible Settings: 001.000.000.000 – 223.255.255.255, Clear

Default Setting: Clear (000.000.000.000)

Specifies the IP address for the port’s default gateway. It is used for packets that do not have a route.

001.000.000.000 – 223.255.255.255 – Shows the IP address for the port, which can be viewed or edited (i.e., a router on the LAN).

Clear – Fills the default gateway’s IP address with zeros.

Proxy ARP

Possible Settings: Enable, Disable

Default Setting: Disable

Determines whether the FrameSaver unit will use the Proxy ARP (Address Resolution Protocol) technique, acting as the gateway to other FrameSaver devices in its management network when there is an ARP request for a device not on the Ethernet.

Enable – Proxy ARP is enabled on the port so the FrameSaver unit will act as an agent for or gateway to other units in its management network. Using this technique, the FrameSaver unit returns its own MAC (Media Access Control) address in response to ARP requests when it recognizes that the destination IP address is in its subnet, but the device sending the ARP request is in another network. Packets sent to the FrameSaver unit’s gateway address are forwarded to the appropriate device.

Disable – The Proxy ARP technique will not be used by the unit; it will not act as an agent for other devices in its network.
