4-58 December 2002 9700-A2-GB20-20
IP Address
Possible Settings: 001.000.000.000–126.255.255.255,
128.000.000.000–223.255.255.255, Clear
Default Setting: Clear (000.000.000.000)
Specifies the IP address needed for the Ethernet management link.
001.000.000.000 – 223.255.255.255 – Shows the IP address for the Ethernet
management link so it can be viewed or edited. The first octet of the address cannot be
decimal 0 or 127, or greater than 223.
Clear – Fills the IP address with zeros.
Subnet Mask
Possible Settings: 000.000.000.000 – 255.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the IP address’s Subnet Mask for the Ethernet management link.
000.000.000.000 – 255.255.255.255 – Sets the Ethernet management link’s subnet mask.
The range for each byte is 000 to 255. When set to 000.000.000.000, the IP protocol
creates a default Subnet Mask based on the IP address’s class
(Class A; 255.000.000.000, Class B: 255.255.000.000, or Class C: 255.255.255.000).
Clear – Fills Subnet Mask with zeros.
Default Gateway Address
Possible Settings: 001.000.000.000–126.255.255.255,
128.000.000.000–223.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the IP address for the Ethernet management link’s default gateway, used for
packets sent out the Ethernet management link that do not have a route.
001.000.000.000 – 223.255.255.255 – Shows the IP address for the Ethernet
management link so the address can be edited. The first octet of the address cannot be
decimal 0 or 127, or greater than 223.
Clear – Fills the default gateway’s IP address with zeros. All packets without a route are
discarded.
Proxy ARP
Possible Settings: Enable, Disable
Default Setting: Disable
Determines whether the Ethernet interface can be used to supply the FrameSaver MAC
address at the opposite end of a PVC by using ARP. This technique is used for
communication between devices on the same network, but on the different subnets. Using
this technique, the Default Gateway Address is provided when there is an ARP request.
When data is sent to the gateway, the gateway forwards the data to the appropriate
device. The gateway acts as an agent destination device.
Enable – Proxy ARP is enabled on the Ethernet interface.
Disable – The Ethernet interface cannot be used to acquire the FrameSaver IP address at
the opposite end of the PVC.
