B.3 TFTP Troubleshooting

If the TFTP request fails even though you have configured your host to 

respond to the request, check the areas discussed in the following table. 

B.4 Entering Commands at the Boot Prompt

If the Bootprompt appears on the serial console instead of the Local 

prompt, one of two things may be wrong. Either the MSS does not have 

enough information to boot, or the network or flash boot has failed. If 

pressing the Return key does not display a prompt, press any other key. 

The Boot prompt should appear. 

If the MSS does not have enough information to boot, or the network or 

flash boot has failed, it will print a message to the console and wait ten 

seconds for serial port activity. If it detects serial port activity, it will 

continue booting provided the flash is good. However, if the user presses 

a key during that ten second time period, the MSS will display the Boot 

prompt. 

NOTE:

If the message “Will attempt another download in x minutes” is 

displayed, press any key for the Boot prompt.

Table B-3:  

TFTP Troubleshooting

Area to Check 

Explanation

Is TFTP enabled on 

the loadhost?

Ensure that the /etc/inetd.conf file has an uncommented line 

enabling the TFTP daemon. Machines may have the TFTP 

daemon line commented out.

If the /etc/inetd.conf file has to be modified, the TCP/IP 

server process (daemon) has to be told of this via a signal. 

Find the process ID (PID) of the inet daemon, and then signal 

the process. Normally, the process is signalled by sending it a 

HUP signal (kill -HUP xxxxx). 

Is the filename 

correct?

The name and case of the software download file must be 

correct. The software file names are uppercase, but can be 

renamed. The server will look for uppercase names by 

default.
