Chapter 2: INSTALLING THE CSMIM-T1

For a successful BOOTP retrieval, a bootpd must be running on a host on 
the same network as the CSMIM-T1 and must have the appropriate 
information in the bootptab file. The CSMIM-T1’s BOOTP 
implementation adheres to rfc 951, rfc1048, and rfc1084. Below is a 
sample bootptab file entry used to initialize the CSMIM-T1 named 
terminator.

csmimt1default:\

:sm=255.255.255.0:gw=132.245.22.66:\
:hn:vm=auto:to=-18000:

terminator:

ht=1:ha=00802d004879:ip=132.245.22.226:
tc=remoteannexdefault:

In the previous example:

sm is the subnet mask

gw is the load/ dump gateway address.

vm is the Vendor Magic Cookie

ht is host type (1=Ethernet)

ha is the CSMIM-T1’s hardware address (Ethernet Address)

ip is the CSMIM-T1’s Internet Protocol Address

When the CSMIM-T1 receives a BOOTP response with the sm, gw, and 
ip set, it sets the respective parameters: subnet_mask, 
load_dump_gateway, and inet_addr. Set vm to auto. This indicates that 
bootpd should respond to the client (CSMIM-T1 in this case) with 
whatever format the client requests; the CSMIM-T1 (client) always 
requests in the decimal dot notation format (99.130.83.99). The bootpd 
adds the address of the host on which it is running as the Server Address 
in the bootp response message. The ROMs use the Server Address as the 
preferred load host and store it in the pref_load_addr parameter.

The bootpd must be running on the CSMIM-T1’s preferred 
load host.
