Chapter 3: Booting/Image Code Loading Problems

3-2 Troubleshooting Guide

3.1 TFTP and BootP Download Guidelines for Personal Computers (PC)

Section 3.1.1 through Section 3.1.4 provide guidelines on how to use a PC running SPECTRUM Element

Manager for Windows, or Remote LANVIEW for Windows (Versions 2.1 or 2.0x) application to TFTP

download to a device using Netmanage or Microsoft’s TCPIP (MSTCPIP) application.

NOTE: In this chapter SPECTRUM Element Manager for Windows and Remote LANVIEW for

Windows are referred to as SPEL and RLVW, respectively.

3.1.1 TFTP Downloading When Using a PC

To TFTP download to a device, proceed as follows:

1. Check that your community name is Read/Write or Super-User. Otherwise, there will be a set failed error

message displayed when you try to initiate the download.

2. Ensure that you use an image file with a .hex extension and that the data path in your Network Management

Station does not go through a BRIM in the device that you are downloading to. If the data path does go

through a BRIM, use the .fls file and do an on-line download.

NOTE: Before doing a .hex download, make sure that the device does not use a BRIM, or that

your Network Management Station is not connected through a BRIM in the device to be

downloaded. Otherwise, when the .hex ﬁle download starts, the device will reboot and

interrupt network trafﬁc, preventing data from being forwarded out of the BRIM port.

3. Ensure that a permanent Address Resolution Protocol (ARP) entry is set. It is necessary when using network

management applications such as (such as SPEL or Remote LANVIEW 2.10) to perform TFTP downloads

to a device. To determine if the ARP entry is already set for a device, check to see if the device icon

displayed by your network management application is green. If the ARP is not set for the device, you need

to determine the MAC address and IP address from the ARP Table of the network management application

being used, then create a permanent ARP cache entry. Section 3.1.1.1 and Section 3.1.1.2 provide

instructions for making permanent ARP cache entries in Netmanage and MSTCPIP, respectively.

For other network management compliant IP stacks besides those of Netmanage or Microsoft, contact the

IP stack vendor on how to set up a permanent ARP entry.

3.1.1.1 Netmanage

To make a permanent ARP cache entry, proceed as follows:

1. Display the Netmanage NEWT table (Figure 3-1) by double clicking on the minimized NEWT icon, which

is in the background when SPEL or RLVW 2.10 is opened.

2. Click on

Tables in the Netmanage NEWT table screen and select ARP from the pull down menu to display

the ARP Table. This table contains the IP address and the MAC (Hardware) addresses.
