Troubleshooting Network Boot Problems

A-3

8. If you are using EZ-Install over a Frame Relay permanent virtual circuit

(PVC) in group access mode, make sure the upstream router’s BOOTP

client interface table is conﬁgured properly.

Router Fails to Netboot

If the router fails to receive the conﬁguration ﬁle or image using a network boot

option, ﬁrst

• Make sure that all cables between the router and the BOOTP server are ﬁrmly

connected.

• If using the

ifconﬁg command, be sure to specify the boot image krnl_an.exe

(not an.exe).

Then refer to the instructions in the following sections until you ﬁnd and correct

the problem:

• Upstream Router Not Receiving BOOTP Requests

• Router Not Sending BOOTP Responses

• BOOTP Server Not Sending BOOTP Responses

If you have not isolated the problem to a speciﬁc interface, retrieve the number of

BOOTP packets forwarded and dropped from all routers between the router and

the BOOTP server. Refer to “Displaying the Number of Packets Forwarded and

Dropped” later in this appendix.

Contact your local Bay Networks Technical Response Center if you perform the

instructions in these sections and cannot ﬁnd and correct the problem.

Upstream Router Not Receiving BOOTP Requests

If the upstream router is not receiving BOOTP request messages, do the

following:

1. Execute the Technician Interface getcfg or ifconﬁg command to display

the router parameters and the

bconﬁg command to correct them if

necessary.

Refer to “Displaying Parameter Settings” and “Debugging the BOOTP

Server” later in this appendix if you need instructions.
