Chapter 2: INSTALLING THE CSMIM-T1
2-12 CSMIM-T1 Hardware Installation Guide
2.7.1 BOOTP
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.
