Starting Configuration Tools

Before configur ing SNMP, BootP, and DHCP services, refe r to t he following user guides for instructions on how to start and use the Nortel Networks configuration tool of your choice.

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 con f igure SNMP, BootP, and DHCP services using the BCC or Site Manager, you must first start IP on the router.

Using the BCC

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 int erface on a slot and connector, navigate to the top-level box or stack prompt and enter:

1-2

<interface_type> <connector_number>

•

interface_type slot_number

•

slot

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

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 ph ys ical inter fac e, navigate to th e prompt f or the physical interface and enter:

ip address <

address

and

address>

mask

mask <

mask>

are a v alid IP address an d its a ssociate d subnet mask, e xpressed

in either dotted-decimal notation or in bit notation. For exampl e, t he f ol lowing command co nfigures IP interface 2.2.2.2/255.0.0.0 on

an Ethernet physical interface on slot 1, connector 2:

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

An IP interface is no w conf igured on the Ethernet inte rf ace with def ault v alues 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.

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:

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 allo ws uni versal read/wri te access. You should restrict read-write acce ss to the router as soon as possibl e by reconf i guri ng the sec urity 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, “Customizing SNMP.”

Before you begin, verify that IP is configured on an interface, as described in “Configuring IP for Global Protocols

Using the BCC

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