Selecting a Boot Configuration

1-15

You use the ifconﬁg and bconﬁg commands with the Technician Interface or

Site Manager to deﬁne

• The IP address of the TFTP server, using

bconﬁg

• The router’s IP address, using ifconﬁg

• The complete pathnames of the startup ﬁles that the router will obtain from

the TFTP server, using

bconﬁg

Directed Netboot is usually reserved for starting the router after the initial startup

because you need to know the exact location of the software image and

conﬁguration ﬁles.

Local Boot

Local booting for routine startups allows you to

• Minimize the time it takes to boot.

Local boot takes 2 to 3 minutes. Typically, Netbooting an image takes a little

longer. Over a low-speed WAN or after conﬁguring the router to run

numerous protocols, Netbooting an image can take up to 15 or 20 minutes.

It also takes less time to local boot a conﬁguration ﬁle than it does to Netboot

one. In most conﬁgurations, however, the difference between the two options

is only a few seconds.

• Minimize line usage.

Getting ﬁles from a BOOTP server adds trafﬁc to your network during the

booting process.

Recommendations

Bay Networks recommends that you

• Set up the network to support Netboot, even if you plan to use the Local Boot

option for the initial conﬁguration and for subsequent restarts.

• Maintain the software image (asn.exe) on the local ﬁle system at all times, in

case you want to use Local Boot to start the ASN.

• Maintain a local conﬁguration ﬁle for the ASN, although it is not required to

Netboot the ASN successfully. The presence of a local conﬁg ﬁle provides

network connectivity if TFTP transfer fails during Netboot.
