Table 4-10. Node IP Options (2 of 3)
Default IP Destination
Possible Settings (Models 9820, 9820-2M, 9820-8M): None, COM,
PVCname
Possible Settings (Model 9820-45M): None, Modem, Ethernet, COM,
PVCname
Default Setting: None
Specifies an IP destination to route data that does not have a specifically defined route.
Examples:
H If the default IP network is connected to the communications port, select COM.
H If the default IP network is connected to a far-end device over the management PVC
named London for the remote device located in the London office, select the PVC
name London (as defined by the Name configuration option, Table 4-11,
Management PVC Options).
NOTE: If the link to the IP destination selected as the default route becomes
disabled or down, the unrouteable data will be discarded. Make sure that
the link selected is operational, and if that link goes down, change the
default destination.
CAUTION: Use care when configuring a default route to an interface that has a
subnet route configured at a remote end where the NMS, router, LAN
adapter, terminal server, etc. is connected. Communicating with an
unknown IP address on the subnet will cause temporary routing loops,
which will last 16 iterations times the retry count.
None – No default network destination is specified. Unrouteable data will be discarded.
This is the recommended setting.
Modem – Specifies that the default destination is connected to the Modem port. Only
appears when Port Use is set to Net Link (see Table 4-19, Modem Port Options).
Ethernet – Specifies that the default destination is connected to the Ethernet port (see
Table 4-16, Ethernet Port Options).
COM – Specifies that the default destination is connected to the COM (Terminal) port.
Only appears when Port Use is set to Net Link (see Table 4-17, Communication Port
Options).
PVCname
– Specifies a name for the management PVC. Only appears when a
management PVC name is defined for the node. For example, when the network is
connected to a remote device located in the London office, London can be specified as
the PVC name, which is the link between the local FrameSaver unit and the one located
in London. London would appear as one of the available selections.
