Chapter 2: INSTALLING THE CSMIM-T1

2.7.1BOOTP

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.

NOTE

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