S UBNET M ASK 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.
E NABLE 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
E 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.
D ISABLE The ATLAS 550 responds to Inverse ARP requests with its IP address for the
requested DLCI. If set to
D ISABLE , the ATLAS 550 does not generate Inverse
ARP request packets. In this case, the F AR -E ND A DDRESS parameter may be
used to statically assign a route address (see the following section, Far-End
Address).
F AR -E ND A DDRESS 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.
M ODE Write security: 2; Read security: 5
Allows RIP to be enabled or disabled on a per-interface basis.Turn off (
O FF )
if you do not want to enable this feature.
T X O NLY
RIP advertisements are periodically transmitted, but are not listened to on
this virtual circuit.
R X O NLY
RIP advertisements are not transmitted on this virtual circuit, but they are
listened to.
