Downloading Firmware
56
AXEL Office Server
The bootp protocol is used to get the IP address of the tftp host and the
firmware filename. This information is returned in response to a broadcast.
The Unix/Linux bootp host, selected for this function, must have been
configured with information concerning this firmware file.
Note: the bootp host and the tftp host can be different machines.
Prerequisites for bootp:
- the bootpd process must be run on the bootp host.
- the bootpd configuration file (/etc/bootptab) must list an entry for every
Office Server which can download firmware.
- the bootp host must be directly accessed by the Office Server (not via a
router). Otherwise a bootp relay host must be set up.
The main capabilities of the bootpd configuration file are as follows:
- tc: network description
- ht: network type
- sa: IP address of tftp host
- sm: network mask
- gw: optional router
- vm: magic number (use only for a router)
- ha: Ethernet address of the Office Server
- ip: IP address of the Office Server (this address is only used during the
downloading operation)
- bf: firmware filename
Examples of bootp configuration files:
a) The Office Server and the tftp host belong to the same network
