Preface

IP utilities a re appl icati on protocols tha t use the I nternet Proto col (IP) for message transport. This guide describes the following IP utilities and what you do to start and customize them on a Bay Networks® router: TCP, FTP, TFTP, Telnet, NTP, NetBIOS over IP, DNS, and IP accounting. To use any of them on a router interface , you must f irst enable IP services on that interface.

You can use the Bay Command Console (BCC utilities on a router. In this guide, you will find instructions for using both the BCC and Site Manager.

Before You Begin

Before using this guide, you must complete the following procedures. For a new router:

• Install the router (see the installation guide that came with your router).

• Connect the router to the network and create a pilot configuration file (see

Quick-Starting Routers, Configuring BayStack Remote Access, or Connecting ASN Routers to a Network).

Make sure that you are running the latest version of Bay Networks BayRS Site Manager software. For information about upgrading BayRS and Site Manager, see the upgrading guide for your version of BayRS.

Starting Configuration Tools

Before configuring TCP, FTP, TFTP, Telnet, NTP, DNS, and NetBIOS over IP services, refer to the foll o wing user guides for inst ructions on ho w to start and use the Bay Networks configuration tool of your choice.

Configuring IP for Global Protocols

Before you configure TCP, FTP, TFTP, Telnet, NTP, DNS, or NetBIOS over IP using the BCC or Site Manager , you must first start IP on the router.

Using Site Manager

Before you can select a protoc ol to run on the router, you must configure a circuit that the protocol can use as an interface to an attached network. For information and instructions, see Configuring WAN Line Services and Configuring Ethernet, FDDI, and Token Ring Services.

When you have successfully configured the circuit, the Select Protocols window opens. Proceed as follows:

Using the BCC

To start IP on the router:

1. Configure a physi cal int erfa ce o n an available slot/connector.

2. Configure an IP interface on the physical interface.

Step 1: Configuring a Physical Interface

An IP interface is now configured on the Ethernet interface with default v alue s for all interface par am et ers. W hen you con figure an IP interface, the BCC also configures IP globally on the router with default values for all IP global parameters.

You can customize IP by modifying IP global and interface parameters as described in Configuring IP Service s.
