Network Ma sk
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 conti g uous .
Descri ptions of Parameters Specific to X.25 Interfac es
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 gua rante es that yo u cannot config ure all 0s or all 1s for a ne twork
ID, node I D, or su bnet ID . (See page 14-1.)
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 Smart-
Switch is used as a default source IP address. (It does not matter what type that
interface is.) All un-numbered interfaces on the SmartSwitch 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 SmartSwitch.
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 can not c onfigur e all 0s o r all 1s for a network ID, node ID, or s u bn et ID. (S ee page
14-1.)
Network Ma sk
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 conti g uous .
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 ass ociated wi th the des tin ation IP inter face por t. (The port i s the f irst
Routing Path configured in the SVC Subscriber record.)
SVC Retry Timer
is the frequency with whic h 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 connectio n is cleared.
Max VCs t o Est a blis h
is the number of virtual circuits over which IP traffic will be transmitted in parallel.
