Chapter 2 Installing the Remote Annex 6300
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; theRemote 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
