Router Fails to Netboot

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

netboot option, first do the following:

• Ensure that all cables between the BayStack router and the BootP server are

firmly connected.

• If using the

ifconfig

command, be sure to specify the boot image file

krnl_an.exe for an AN/ANH or krnl_arn.exe for an ARN.

Then, refer to the instructions in the following sections to 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 BayStack

router and the BootP server. See “Displaying the Number of Packets Forwarded

and Dropped” on page B-16

If you perform the instructions in these sections and cannot find and correct the

problem, contact the Nortel Networks Technical Solutions Center.

Upstream Router Not Receiving BootP Requests

If the upstream router is not receiving BootP requests, do the following:

Issue the Technician Interface

getcfg

command to display the router

parameters and the

bconfig

ifconfig

command to correct them, if

necessary.

For instructions, see “Displaying Parameter Settings” on page B-10

and

“Debugging the BootP Server” on page B-12

Ensure that the BayStack router’s netboot interface is cabled properly.

For EZ-Install, ensure that the synchronous port is cabled to the upstream

router. For Netboot or Directed Netboot, ensure that the configured

synchronous, Ethernet, or ARN token ring interface is cabled to the IP

network.
