Frame Relay Module 4. 0 User G uide, Rev 01
is the IP address of the end-to-end sender. The valid range of values guarantees that
you cannot configure all
0
s or all
1
s for a network ID, node ID, or subnet ID. (See
page
13-1
.)
Network Mask
is used during routing to determine the portion of the address associated with the
network and subnetwork (if any). All bits associated with the network/subnet should
be set to
1
, and must be contiguous.
Descriptions of Parameters Specific to X.25 Interfaces
Destination IP Address
is the IP address of the end-to-end receiver for point-to-point X.25 connections. The
valid range of values guarantees that you cannot configure all
0
s or all
1
s for a network
ID, node ID, or subnet ID. (See
page 13-1
.)
Unnumbered Interface
allows the point-to-point frame relay interface to be configured without specifying a
source IP address. If
Y
, the address of the lowest IP interface number (not the lowest
address, but the number, in the range
0–256
, that identifies the interface) in the FRM
is used as a default source IP address. (It does not matter what type that interface is.)
All un-numbered interfaces on the FRM use the same default address.
If a new interface with a lower number is added, that interface’s address will become
the new default source IP address, but only after the next IPL of the FRM.
Naturally, this feature works only if there is at least one numbered interface in the
device. If there are none, all un-numbered interfaces remain disabled. Once a num-
bered interface is added, all un-numbered interfaces will become active.
Source IP Address
is the IP address of the end-to-end sender. The valid range of values guarantees that
you cannot configure all
0
s or all
1
s for a network ID, node ID, or subnet ID. (See
page
13-1
.)
Network Mask
is used during routing to determine the portion of the address associated with the
network and subnetwork (if any). All bits associated with the network/subnet should
be set to
1
, and must be contiguous.
Source Subscriber
is a subscriber ID associated with the source IP interface port. (The port is the first
Routing Path configured in the SVC Subscriber record.)
Destination Subscriber
is a subscriber ID associated with the destination IP interface port. (The port is the first
Routing Path configured in the SVC Subscriber record.)
SVC Retry Timer
is the frequency with which calls will be placed to try to establish an X.25 connection.
SVC Idle Timer
is a period that IP remains active with no traffic before the X.25 connection is cleared.
