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.

NABLE

The ATLAS 550sends 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

NABLE

, 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.

ISABLE

TheATLAS550respondstoInverseARPrequests withitsIPaddressfor the

requested DLCI. Ifset toD

ISABLE

, the ATLAS550 does not generate Inverse

ARP request packets. In this case, theF

-E

DDRESS

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 itis only selectablewhen Inverse ARPis disabled. The IP address

of the device onthe other endof thevirtual circuitmay be specified. Astatic

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

if nonzero. If 0.0.0.0has been specified for the Subnet-Mask,adefaultsubnet

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.

ODE

Write security: 2; Read security: 5

Allows RIP tobe enabledor disabled ona per-interface basis.Turn off (O

)

if you do not want to enable thisfeature.

NLY

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

this virtual circuit.

NLY

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

listened to.
