Chapter 2 Installing the Remote Annex 6300
2-20
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 Remote Annex 6300 ’s hardware address (Ethernet
Address).
❑ ip is the Remote Annex 6300’s Internet Address.
When the Remote Annex 6300 receives a BOOTP response with the sm,
gw, and ip set, it sets the respective parameters: subnet_mask,
load_dump_gateway
, and inet_addr. The Vendor Magic Cookie
must be set to auto. This indicates that bootpd should respond to the
client (Remote Annex 6300 in this case) with whatever format the
client requests; the Remote Annex 6300 (client) always makes requests
in the decimal dot notation format (e.g., 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 Remote Annex’s preferred
load host.
RARP
If the Remote Annex 6300 does not receive a successful BOOTP
response, it uses RARP to get the boot information. For a successful
RARP retrieval, TCP/IP must be running on a host that is on the same
network as the Remote Annex 6300, and the host’s ARP table must
be initialized with the Remote Annex 6300’s Internet and Ethernet
addresses (see the arp man page, arp –s
) .
