Address Defines the individual interface IP address. If this field is left as
0.0.0.0, it is treated as an unnumbered interface.
Subnet Mask 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 The Inverse ARP (IARP) field is only present when this is a frame
relay network interface. The Express 5210 always responds to
IARP requests with its IP address for the requested DLCI.
E
NABLE
: The unit sends IARP packets in order to determine the IP
address on the other end of the virtual circuit. If the IARP packet is
responded to, a route is placed in the IP route table.
D
ISABLE
: The Express 5210 responds to IARP requests with its IP
address for the requested DLCI. If set to D
ISABLE
, the
Express 5210 does not generate IARP request packets.
Far-End Address The F
AR
-E
ND
A
DDRESS
field is present for PPP, SLIP, and frame
relay network interfaces (with IARP 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 inter-
face 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 F
AR
-E

DDRESS
.
MTU Defines maximum number of bytes in a datagram transmitted over
this interface.
RIP RIP selections vary depending on selections made for M
ODE
. See
the following section, RIP Selections on page 12-9 , for more infor-
mation.
Proxy ARP Enables the interface to respond to ARP broadcasts for networks
which are present in the route table.
