3.4 Firmware update
3.4.1 Plug-in
Firmware of the Watson Ethernet plug-in can be updated remotely using the
TFTP protocol. To load a new firmware package into a plug-in, copy the package
on the TFTP server and use the UPDATE GET Monitor command to load the new
package into the plug-in.
Once the new package is loaded in it must be activated. This is done with the
UPDATE COMMIT command. The plug-in will automatically reboot to activate the
new firmware package.
If there are any problems with the newly loaded firmware package then it is poss-
ible to revert to the last installed package using the UPDATE REVERT command.
3.4.2 Tabletop
The Watson Ethernet tabletop firmware can be upgraded either through the local
RS-232 monitor port or remotely from a Watson Ethernet plug-in modem through
the DSL span.
In the first case a PC with the Watson Flashloader application [10] must be used
to load a new firmware package into the tabletop. This PC must be connected
the RS-232 interface of the tabletop modem.
In the second case a new firmware package can be transferred into the tabletop
through the DSL span and the Watson Ethernet plug-in using the TFTP protocol.
This is controlled by the DOWNLOAD Monitor command, cf. 7.5.4.
3.5 Management
3.5.1 Management interfaces
Watson Ethernet modems have several management possibilities:
Management through a local RS-232 port using a command line interface
(Monitor)
DSL slave modems (STU-R) can be managed inband through the DSL EOC
from the DSL master modem.
The Watson Ethernet plug-in modem has a dedicated Ethernet interface (Q –
Interface) for remote management through Telnet or SNMP.
SNMP and Telnet management are also available through the Ethernet user
interfaces of the Watson Ethernet plug-in modem (Ethernet inband manage-
ment). Normally a dedicated management VLAN is used in this case.
Ethernet inband management is also possible through a DSL span that is
terminated by a Watson Ethernet plug-in modem.
