Introduction
Set-up and
Operation
To configure the IP address using RARP or BOOTP, refer to the
RARP/BOOTP host documentation.
Many BOOTP daemons will not reply to a BOOTP request if the down-
load filename in the configuration file does not exist. If this is the case,
create a file in the download path to get the BOOTP daemon to respond.
If the LSB4 has no IP address, it will set its address from the first directed
IP address it receives. To generate such a packet, create an entry in the
hostÕs ARP table [Figure 3-2]. Note that this requires that privileged user
status.
Figure 3-2: Creating ARP Entry
Substitute the intended IP address and the hardware address of the
switch. Then ping the switch using the following command [Figure 3-3]:
Figure 3-3: Ping Command
When the switch receives the ping packet, it will notice that its IP address
is currently not set and will send out broadcasts to see if anyone else is us-
ing this address. If no duplicates are found, the switch will use this IP ad-
dress and will respond to the ping packet. The LSB4 will
not save this
learned IP address permanently. It is intended as a temporary measure to
enable the administrator to telnet into the LSB4Õs console port.
Any host wishing to access the LSB4 will have to be given the LSB4's IP ad-
dress. This is typically configured in the file
/etc/hosts or can be obtained
via a nameserver. Refer to the host's documentation for additional infor-
mation.
