Running Head
TCP/IP Network Management CPU Card
HOST NETMASK
The Host Netmask is used to indicate how much of the IP address is used for host addressing
and how much is used for network addressing.
If the B7R card is used for this NMS, the CPU netmask address must be the same as the one
entered in the
NETMASK
field of that card.
HOST TYPE
The Host Type is used to control IP forwarding. When Host Type is set to
gateway
, IP
datagrams are allowed being forwarded. When Host Type is set to
host
, no forwarding is
allowed. For IP forwarding (routing) to work correctly, a route must be created in the routing
table.
DEFAULT IP PORT
The Default IP Port setting (Figure 5-7), tells the CPU card where IP packets will be sent when
there is no matching entry in the routing table. The options are
none
(no default route used),
local
(SLIP/PPP over DB-9 serial port),
wan
(W1 W2 W3 W4) (FDL/SA4 or B7R [chosen on
the WAN card main screen with ESF/NMS RPT option])
servr
(P1 P2 P3) (WAN DS0s or
Ethernet depending on type of server card) or
nX64
(C1, C2, C3, C4 WAN nx64 ports).
If this parameter is set to
local
,
wan
or
servr,
the Print Alarms feature (mentioned in the
previous section) must be set to
off
. If
local
is chosen for this setting, the internal modem will
not operate.
If this parameter is set to
nX64
, the default IP port selected is
nX64
, packets will be directed
to one of the four nX64 ports selected (
C1, C2, C3
or
C4
). (Refer to Default IP Unit below).
