Chapter 6 - Basic Configuration Guide 31
SMDS Configuration
This section covers the settings required for SMDS (Switched Multi-
megabit Data Service) operation of the RISC Router 3500R WAN in ter-
faces. SMDS is a connectionless, packet-switched service that offers
LAN-to-LAN connectivity across a wide area at up to 1.544 Mbps. In
general, the parameters listed here should be set for each WAN interface
on which you plan to use SMDS. Note that some WAN interfaces can
be running SMDS while others are running PPP or Frame Relay.
v 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.
Link Configuration
SMDS is presently supported in the RISC Router 3500R only via
synchronous dedicated line operation. It can only be set using text-
based configuration.
•Set Dedicated connection
•Set SMDS connection
TB: Use configure and then set the Mode and ConnectMode
keywords in the Link Config WAN 0 (and/or other port numbers
you wish to configure) section.

SMDS Addressing

SMDS addresses and other parameters can only be set using the
command line interface. Many of these parameters will be given to you
by your service provider.
TB: Use configure and set the StationAddress, IPMulticast and Poll-
ingFrequency keywords in the SMDS WAN 0 (and/or other port
numbers you wish to configure) sectio n .
