Understanding the Discovery Process

Once you have logged in, the RAS Management Tool automatically searches the LAN

for AWAN access servers. As the RAS Management Tool discovers AWAN access

servers, they are displayed as server icons at the bottom of the RAS Management Tool

window.

When it is initially displayed, a server icon is labeled with the default name of the

AWAN access server. Default names begin with the letters RA or TS followed by the last

six digits of the AWAN access server’s media access control (MAC) address. RA

indicates an R model, such as the 3884R, and TS indicates a base model, such as the

3884. An example of a server icon is shown in Figure 5-9

on page 5-12.

If your AWAN access server is in an IP environment, it will not be discovered until it has

been assigned an IP address. An IP address can be assigned to an AWAN access server

in the following ways:

•

By a Dynamic Host Configuration Protocol (DHCP) server. This method of IP

address assignment is described in Obtaining an IP Address From a DHCP Server

on page 5-5.

•

By configuring the BOOTP Service. This method of IP address assignment is

described in Assigning an IP Address Using the BOOTP Service on page 5-5.

•

By using Command Line Interface (CLI) commands. CLI commands are described

in Appendix C, Command Line Interface (CLI) Commands.

If the management workstation is on a different subnet than your AWAN access server,

you must configure the Learn Service before your AWAN access server will be

discovered by the RAS Management Tool. Configuring the Learn Service is described in

What to Do If Your AWAN Access Server Is On a Remote Subnet

on page 5-7.

If your AWAN access server in an Internet Packet Exchange (IPX) environment, the

AWAN access server monitors network traffic to determine its IPX address and the

values of other IPX parameters. You can override some IPX parameter settings; refer to

Configuring IPX Properties

on page 6-6 for more information.

Note. The RAS Management Tool attempts to discover a new AWAN access server every 30

seconds using a Simple Network Management Protocol (SNMP) broadcast. You can disable

this SNMP broadcast using the Discovery option. The Discovery option is described in

Configuring the Discovery Option on page 5-20.
