SUBNET MASK

Write security: 2; Read security: 5

 

Defines the subnet mask applied to the address defined for this link. If the

 

subnet mask is unnumbered, leave as 0.0.0.0.

IARP

Write security: 2; Read security: 5

 

The Inverse ARP (IARP) field is only present when this is a frame-relay net-

 

work interface. The ATLAS 550 always responds to Inverse ARP requests

 

with its IP address for the requested DLCI.

ENABLE

The ATLAS 550 sends Inverse ARP packets in order to determine the IP ad-

 

dress on the other end of the virtual circuit. If the Inverse ARP packet is re-

 

sponded to, a route is placed in the IP route table. When this field is set to

 

ENABLE, the ATLAS 550 dynamically sends Inverse ARP packets to deter-

 

mine the IP address on the other end of the virtual circuit. When an Inverse

 

ARP packet is not responded to, a route is placed in the IP route table.

DISABLE

The ATLAS 550 responds to Inverse ARP requests with its IP address for the

 

requested DLCI. If set to DISABLE, the ATLAS 550 does not generate Inverse

 

ARP request packets. In this case, the FAR-ENDADDRESS parameter may be

 

used to statically assign a route address (see the following section, Far-End

 

Address).

FAR-END ADDRESS

Write security: 2; Read security: 5

 

The Far-End IP Address field is only present for frame-relay network inter-

 

faces, and it is only selectable when Inverse ARP is disabled. The IP address

 

of the device on the other end of the virtual circuit may be specified. A static

 

route to the far-end network will be added using the interface Subnet-Mask

 

if nonzero. If 0.0.0.0 has been specified for the Subnet-Mask, a default subnet

 

mask is used based on the class of the Far-End Address. (See also the previ-

 

ous section, Subnet Mask.)

MTU

Read security: 5

 

Defines maximum number of bytes in a datagram transmitted over this

 

interface. (Maximum Transmit Unit)

RIP

Configures routing information protocol (RIP) on this interface.

MODE

Write security: 2; Read security: 5

 

Allows RIP to be enabled or disabled on a per-interface basis.Turn off ( OFF)

 

if you do not want to enable this feature.

 

TX ONLY

 

RIP advertisements are periodically transmitted, but are not listened to on

 

this virtual circuit.

 

RX ONLY

 

RIP advertisements are not transmitted on this virtual circuit, but they are

 

listened to.
