Solving Startup Problems

This section identiﬁes and recommends procedures for isolating and correcting

the four most common router startup problems.

The console connected to the router console port displays error messages to

indicate each problem. Refer to the appropriate section:

• “Router Fails to Get IP Address”

• “Router Fails to Netboot”

• “ASN Fails to Perform Directed Netboot”

• “ASN Netboots, But Fails to Load Applications”

Router Fails to Get IP Address

If a message at the router console indicates that the router failed to get an IP

address from the upstream router, or if the upstream router is failing to receive

BOOTP requests or respond to them, make sure the network cable between the

router’s synchronous port and the upstream router is ﬁrmly connected. Then refer

to the instructions in the following sections, or in the section that applies to your

problem, until you ﬁnd and correct the problem:

• “Upstream Router Not Receiving BOOTP Requests”

• “Upstream Router Not Sending BOOTP Responses”

Contact the Bay Networks Technical Response Center if you follow 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, use the getcfg

command to display the router parameters and the bconﬁg and ifconﬁg

commands to correct them if necessary. Refer to “Displaying the ASN’s

Parameter Settings” and “Changing the ASN’s Parameter Settings” later in this

appendix if you need instructions.
