Configuring SNMP, BootP, and DHCP Services

Starting Configuration Tools

Before configuring SNMP, BootP, and DHCP services, refer to the following user guides for instructions on how to start and use the Nortel Networks configuration tool of your choice.

Configuration Tool User Guide

Bay Command Console (BCC) Using the Bay Command Console (BCC)

Site Manager Configuring and Managing Routers with Site Manager

These guides also describe generically how to create and modify a device configuration.

Configuring IP for Global Protocols

SNMP, BootP, and DHCP services all use the Internet Protocol (IP) for message transport. Before you configure SNMP, BootP, and DHCP services using the BCC or Site Manager, you must first start IP on the router.

Using the BCC

1-2

To start IP on the router:

Configure a physical interface on an available slot/connector.

Configure an IP interface on the physical interface.

Step 1: Configuring a Physical Interface

To configure a physical interface on a slot and connector, navigate to the top-level box or stack prompt and enter:

<interface_type> <connector_number>

interface_type

•

slot_number

•

slot

is the name of a link or net module on the router.

is the number of the slot on which the link or net module is

<slot_number>

module

[

<module_number>

connector

]

located.

308644-15.1 Rev 00

Starting SNMP, BootP, and DHCP Services

module_number

•

is the net module number (ASN* and System 5000* routers

only).

connector_number

•

is the number of a connector on the link or net module.

For example, the following command configures an Ethernet interface on slot 1, connector 2:

box#

ethernet slot 1 connector 2

ethernet/1/2#

Step 2: Configuring an IP Interface

To configure an IP interface on a physical interface, navigate to the prompt for the physical interface and enter:

ip address

address

and

address>

mask

are a valid IP address and its associated subnet mask, expressed

mask>

in either dotted-decimal notation or in bit notation.

For example, the following command configures IP interface 2.2.2.2/255.0.0.0 on an Ethernet physical interface on slot 1, connector 2:

ethernet/1/2# ip/2.2.2.2/255.0.0.0#

ip address 2.2.2.2 mask 255.0.0.0

An IP interface is now configured on the Ethernet interface with default values for all interface parameters. When you configure 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, ARP, RARP, RIP, and OSPF Services.

308644-15.1 Rev 00

Configuring SNMP, BootP, and DHCP Services

Using Site Manager

Before you can select a protocol 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:

Site Manager Procedure

1. In the Select Protocols window, select IP. Then click on OK.

If you plan to add BootP or DHCP services, you can also select BootP.

Starting SNMP Services

You can use the BCC command-line interface or the Site Manager graphical user interface to start SNMP on the router, accepting default values for all parameters.

SNMP is globally enabled on the router by default when you install BayRS software. By default, the Quick-Start installation script (install.bat) creates a read/write SNMP community named “public” with a wildcard manager (0.0.0.0) that allows universal read/write access. You should restrict read-write access to the router as soon as possible by reconfiguring the security of this SNMP community. When you add SNMP with the BCC, access is defined by default as read-only.

If you decide to change some or all of the default values, refer to the instructions in Chapter 3

Before you begin, verify that IP is configured on an interface, as described in

“Configuring IP for Global Protocols

To configure SNMP on the router with default settings, begin in configuration mode at the box or stack prompt:

Before you begin, you must verify that IP is configured on an interface, as described in “Configuring IP for Global Protocols enable IP, BootP, and BootP/DHCP on the router simultaneously.

Starting a DHCP Server

You can use either the BCC or Site Manager to start a DHCP server.

Before you begin, you must do the following:

Verify that IP is configured on an interface, as described in “Configuring IP

for Global Protocols” on page 1-2.

Configure TCP on the router. For instructions on how to configure TCP on a router, see Configuring IP Utilities.

Configure the NetID* Server Manager to communicate with the DHCP server.

For the DHCP server to operate, you must first install the NetID Server Manager on a Microsoft it to communicate with the DHCP server. Typically, you install the NetID Server Manager on the same workstation as the one that contains the NetID database.

Because the DHCP server uses the information in the NetID database to assign IP addresses and host configuration information, you need to set up your network configuration using the NetID Management Console before the DHCP server can operate correctly.
