Chapter 3. Line Options
TELNET Host Connections
Although this option is found on the panels of the SCON-20L and SCON-22L, the only
valid option is to use a value of 0, which in effect disables this feature (no VHP card to
support the feature). The SCON-25L and SCON-28L may be configured to support
Telnet Host Sessions if desired. Up to 32 Telnet Host Sessions may be supported without
installing a FAD. Up to 256 may be configured if the Telnet FAD is installed.
TN3270 Client Connections
If the SCON-2XL will be supporting TN3270 clients, you must indicate the number of
sessions that are to be supported through this interface. Up to 32 sessions (16 sessions
on the 20L) may be configured without requiring any feature activation disks (FAD).
Additional sessions, up to 256 per installed ESCON interface, may be supported through
the installation of the TN3270 FAD. The FET card can support all 512 TN3270 sessions.
IP Router
When enabled, LINCS will provide IP routing through this interface if two or more
networking interfaces are installed. Routing choices include:
• Static Routing Only - All routing table entries must be made statically.
• Static and Dynamic Routing - LINCS will add entries into the routing table based
on RIP V1 and RIP V2 broadcasts that have been received, but LINCS will not
broadcast the contents of the routing table to other routers.
• RIP Version 1 - LINCS will add entries into the routing table based on received RIP
V1 and RIP V2 broadcasts, and will broadcast the contents of the routing table using
RIP V1.
• Rip Version 2 - LINCS will add entries into the routing table based on received RIP
V1 and RIP V2 broadcasts, and will broadcast the contents of the routing table using
RIP V2.
BSD 4.2 IP Broadcast
If this option is enabled, LINCS will send two broadcasts. One is 4.2 compatible, and
the other is the standard broadcast address.
Note:
BSD 4.2 broadcasts use all 0s as the destination address. Other implementations
as well as BSD 4.3 use all 1s as the destination address. If this option is disabled,
LINCS will send the standard broadcast address only.
Expanded IP Addressing
This is a special customer request feature that allows using IP addresses that are illegal
for the worldwide Internet.
For example, 192.000.000.xxx would normally be reserved, but with this field enabled,
an address of that type can be entered.
