Management

Connecting the Communications Server to Your Network

You can use the communications server in a LAT network, in a TCP/IP network,
or in a network that includes both protocols.

To issue commands to the communications server, connect a terminal into port
one of the communications server; it is preconfigured to be the console port. Press
Return two or three times and the communications server responds by displaying
a prompt on the terminal. It is convenient to use this terminal to perform all
subsequent configuration described in this chapter.

Management tasks described in this chapter require the user to be in privileged
mode. To enter privileged mode type:

Local> SET PRIVILEGED

Respond with the privileged password. The factory default value for the
privileged password is SYSTEM.

LAT Network

If you are using the communications server in a DECnet network using the
LAT protocol, no configuration is required. The communications server is
preconfigured to use the LAT protocol. You can, however, customize various
communications ports characteristics such as the following:

Change the authorized LAT group codes

Change the communications server name

Change the communications server number

Change the identification string

Set the circuit timer to optimize system performance

Set the keepalive timer and retransmit limit to optimize system performance

For details, refer to "Configuring and Maintaining a Communications Server on a
Network" in Ethernet Communications Server Management.
