Chapter 9 Updating the device firmware

Firmware updating in the device requires two parameters:
• The name of the file containing the firmware (fwethant.img).
• The IP address of the server that contains above file.
Both parameters are configured in DHCP.
protocol dhcp
; -- DHCP Configuration --
server
; -- DHCP Server Configuration --

subnet teldatsubnet 0 network 172.24.0.0 255.255.0.0
subnet teldatsubnet 0 bootfile fwethant.img
subnet teldatsubnet 0 next-server 172.24.78.29
subnet teldatsubnet 0 router 172.24.78.29

host eth-ant 0 client-id asc teldat
host eth-ant 0 fixed-ip 172.24.78.28
host eth-ant 0 option 43 asc antenna
;
exit
;
exit
;
The bootfile parameter indicates the startup file name (file containing the firmware).
The next-server parameter indicates the IP address for the server, which stores the file containing the firmware.
For a Cisco router, the DHCP configuration is as follows:
ip dhcp pool ethant
host 172.24.78.28 255.255.0.0
client-identifier 7465.6c64.6174
bootfile fwethant.img
next-server 172.24.78.29
option 43 ascii antenna&routertype=generic&apn=internet.es&pin=5710
default-router 172.24.78.29
!
The comments for this configuration are the same as for a Teldat router.
The Teldat-3Ge-USB firmware is transmitted from the server to the device through TFTP (Trivial File Transfer Pro-
tocol). The Teldat-3Ge-USB sends periodic petitions (every 30 seconds) to the TFTP server, checking if the version
saved in the server is different to the one currently executing. If different, it downloads the new application in the
device and subsequently restarts.
The user can check the version running in the Teldat3Ge-USB in various different ways. If you're using L2TP, check
by looking at the created L2TP tunnels' hostname. By running tunnel-info all in a Teldat router's L2TP monitoring
menu, you get:
RemoteIP:10.1.2.2
RemoteName:01.00-EthAnt-00
LocalID:9240
group 3
Pseudowire:ETH-ANT-MON
(...)
By running show 12tun session all in a Cisco router, you get:
L2TP Session Information Total tunnels 1 sessions 1
76
LocalIP:0.0.0.0 Port:1701
State:established
RemoteID:1589 Sessions:3
Interface:rcellular1 Sequencing:off
