Enterasys Networks XSR-3020 manual Opening a COM Console Session, Configuring RAI for Frame Relay

Opening a COM (Console) Session

first error will be reported, along with a count of the sum of errors incurred. In the case of a single error, only the error line will be reported. Error messages will be logged as well. Because the result of continuing to process a flawed startup-configis not predictable, the nature and position of the syntax error may cause the erroneous configuration of the XSR.

•Router ports and protocol stacks are initialized based on startup configuration.

•Alarms and messages reported during initialization are logged.

•COM is up.

•The XSR is up.

To view the screen output produced when the XSR reboots, refer to “XSR Rebooting

Characteristics” on page 3-32.

Opening a COM (Console) Session

1.Open a COM (console) session to the XSR using a communications program.

Set the session properties as follows: BPS - 9600, Data bits - 8, Parity - none, Stop bits - 1, Flow control - none. Refer to “Initialization Output” on page 3-32 to view XSR initialization data.

2.When the XSR login appears, enter admin and enter no (blank) password. Note that logins and passwords can be changed later.

Note: You can abort RAI at any time by pressing any key.

Refer to the following section for quick configuration of RAI. For a full description of RAI including how it works, refer to “Chapter 2: Managing the XSR” in the XSR User’s Guide.

Optional: Configuring Remote Auto Install

In short, the RAI application transports a startup configuration file from a TFTP server for use in configuring the remote XSR. This file is placed in the Flash: directory as the startup-configand executed via the normal startup process. RAI is supported on a Frame Relay network running on a serial NIM card (configuration example shown below), RAI over Ethernet (with DHCP), RAI PPP over a Leased line or RAI over an ADSL network.

For remote XSR setup, you need only hook up cabling as described in ”Chapter 2: Hardware Installation” of this guide.

Configuring RAI for Frame Relay

To configure two remote XSRs with RAI over Frame Relay, perform the following setup on the central site. On multi-point Serial sub-interface 1/0.1, configure DLCIs 16 and 18 to statically map to IP addresses 133.133.1.2 and 133.133.1.3. If the DLCI will onnect to a remote XSR running RAI, then add the bootp parameter after the static IP address.

This configuration supports two remote XSRs connected on DLCIs 16 and 18. Make sure with your Frame Relay provider that these DLCIs terminate at the location of the remote XSRs. To add more remote XSRs, you will need additional DLCIs.

Note the use of a helper-addressto specify a destination address for UDP broadcasts and forward traffic to the DNS and TFTP servers. In the example below, DNS and TFTP servers reside on the
