Downloading Firmware
168 TCP/IP AX3000 User's Manual
The bootp protocol is used get the location (IP address of the tftp host and
filename) of the firmware file. This information is obtained by means of a
broadcast.
Information concerning this firmware file must have been configured within the
selected UNIX host (known as the bootp host).
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
AX3000 which can download firmware.
- the bootp host must be directly accessed by the AX3000 (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
- gw: optional router
- ha: Ethernet address of the AX3000
- ip: IP address of the AX3000 (this address is only used during the
downloading operation)
- bf: full firmware file name (path included)
Examples of bootp configuration files:
a) When the AX3000 and the tftp host are on the same network
net:hn:df=/etc/btdump:ht=ethernet:sa=192.168.1.252:to=auto:
axel1:tc=net:ht=ethernet:ha=00A034000001:ip=192.168.1.242:bf=/tmp/axel:
b) When the AX3000 accesses the tftp host via a router
net:hn:df=/etc/btdump:ht=ethernet:sa=192.1.1.243:to=auto:
net1:tc=net:sm=255.255.255.000:gw=192.168.1.252:
axel1:tc=net1:ht=ethernet:vm=rfc1048:ha=00A034000001:ip=192.168.1.242:bf=
