4. Configuration Options

4-75
Default IP Destination
Possible Settings: None, Modem, COM, Ethernet,
PVCname
Default Setting: None
Specifies an IP destination to route data that does not have a specifically defined route.
Examples:
If the default IP network is connected to the communications port, select COM.
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 4-18, 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 the modem port Use option is set to Net Link.
COM – Specifies that the default destination is connected to the COM port. Only appears
when Port Use is set to Net Link (see Table 4-24, Communication Port Options).
Ethernet – For the FrameSaver SLV 9126-II or 9128-II, specifies that the default
destination is connected to the Ethernet port. Only appears when the Ethernet port’s
Interface Status option is enabled. When selected, the Default Gateway Address must
also be configured (see Table 4-23, Ethernet Management 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.
TS Access Management Link
Available Settings: None,
PVCname
Default Setting: None
Specifies a troubleshooting management link for the special needs of network service
providers.
If the setting is changed from the management PVC name to None, the
Delete the
Management PVC
PVCname and the associated DLCI Record?
prompt appears.
If you select:
No – The link designation is removed and the option is set to None.
Ye s – The link designation is removed and the option is set to None, and the link
and its DLCI will be deleted.
None – Disables or does not specify a TS Access Management Link.
PVCname – Specifies the name of the TS Management PVC.
Display Conditions – This selection only appears when a dedicated management PVC
has been defined on the network frame relay link as a DLCI with DLCI Type set to
Standard.
