Chapter 6 - Basic Configuration Guide 31
WAN 0 SMDS Configuration
This section covers the settings required for SMDS (Switched
Multi-megabit Data Service) operation of the MicroRouter 2250R WAN
0 interface (IP only). SMDS is a connectionless, packet-switched
service that offers LAN-to-LAN connectivity across a wide area at up to
1.544 Mbps. Note that the RS-232 (WAN 1) interface can be running
Frame Relay or PPP while this interface is running SMDS, Frame Relay
or PPP. SMDS addresses and other parameters can only be set using the
command line interface.
Note: The IP protocol settings and the physical communication
settings are the same as they would be for Frame Relay operation. The
only parameters which should be set differently for SMDS are the Link
Configuration and the SMDS addressing section.
Internal T1 CSU/DSU (WAN 0) Link Configuration
SMDS is presently supported in the MicroRouter 2250R only via
synchronous dedicated line operation.

TB:Useconfigure and then set the Mode and ConnectMode
keywords in the Link Config WAN 0.
SMDS Addressing
Many of these parameters will be given to you by your service provider.
CV: Use Link Configuration: WAN 0 (and/other ports), select SMDS
from the Link Type pull-down menu, and click on the SMDS
button.

Saving a Configuration File to Flash ROM
Once a configuration is complete, you can save it to the router’s Flash
ROM. Until saved, all changes are made in a separate buffer and the
actual router interfaces run as before the changes were made.
CV: Use the Save to/Device option from the File menu.
TB: Use the save command.
