Oki 6010E manual Tcp/Ip

Section IV - TCP/IP

The ht signifies hardware type. For the OkiLAN 6010e, it will always be ether for an Ethernet device and token for a Token-Ring device. The ha signifies the network hardware address. For BOOTP, the network hardware address must be represented without the colons between each byte. The ip part of the entry is where the IP address is specified. There are several other parameters that can be specified in a bootptab entry. However, the three parameters shown here are the only ones required for OkiLAN 6010e installation.

The following sequence of events occurs during the power up of the OkiLAN 6010e using BOOTP.

1.An OkiLAN 6010e powers up but does not know its IP address. (It does know its net- work hardware address.)

2.The OkiLAN 6010e sends out a BOOTP request packet with its network hardware address. For this example, the network hardware address is 00:40:68:17:50:A4.

3.The bootpd daemon running on a BOOTP server (which in this example is a UNIX workstation) sees the BOOTP request along with the network hardware address. It looks up the network hardware address in the “/ etc/bootptab” file. The bootpd daemon finds the associated IP address of the device in the bootptab file.
