Managing The ADSL Router
5.1 Booting the ADSL Router from Ethernet Network
By default, the Router is configured to boot from the on-board flash memory. But it is possible boot via
Ethernet network as well. The executable image is stored in the local PC and is downloaded to the
Router via Ethernet network upon every reset. For this, the Router needs to be configured and also a
TFTP/BOOTP utility needs to be installed on the local PC.

Local PC Configuration
To download the software you need a TFTP/BOOTP server. You can use any. Be aware that
every time the board is restarted the image will be transferred from the local PC to the Router.
5.2 Upgrading on-board flash memory from Ethernet network
You can update the on-board flash memory after you booting the new firmware from the Ethernet
network by issue the following commands.
>
home
↵
> flashfs rewrite boot.bin
↵
(
this command is available for update boot code only)
> flashfs update
↵
> flashfs ls
↵
You should see some messages about the file name and file sizes that stored in the Router. If you get “
no
flash content
” something went wrong.
5.3 SNMP
The ADSL Router provides SNMP agent support standard MIBs. SNMP is also used internally for
configuration of the router. The active SNMP agent within the Router accepts SNMP requests for status,
statistics, and configuration updates. Communication with the SNMP agent occurs over the LAN or
WAN connection. Any management application using SNMP over UDP/IP (User Datagram
Protocol/Internet Protocol) has access to the local SNMP agent. The following MIBs are supported:
z
MIB II (RFC 1213)
z
Bridge MIB (RFC 1493)
z
PPP/LCP MIB (RFC 1471)
z
PPP/Security MIB (RFC 1472)
z
PPP/IP MIB (RFC 1473)
z
PPP/Bridge MIB (RFC 1474)
