DVB3030/DVB3030L Digital Video Broadcast Modulator User Interfaces
TM052 - Rev. 3.5 4-43
Aside from the Modem Ethernet Address, which is set at the factory, the user is able to modify
the SNMP Parameters from the Terminal Interface depending on the SNMP mode of operation.
4.4.2.5 Setting the SNMP Mode
There are two SNMP modes of operation: Normal and Test. When in Normal Mode, the user
has the capability to modify the settings for the Server IP Address, the IP Address Mask, the
Community String, and the Boot Mode. When in Test mode, these additional parameters can be
modified: Modem IP Address, Server Ethernet Address, Server Host Name, and the Router IP
Address. These later parameters are only accessed in Test Mode to make the user aware that
he might be overriding settings downloaded through a BOOTP Server.
From the Main Menu, select ‘8’ for Ethernet Configuration. Select '31' and press the Enter Key.
Scroll through to the desired selection of either 'Normal' or 'Test' and press the Enter Key.
4.4.2.6 Setting the Boot Mode
Select '44' from the Configuration Screen and press the Enter Key. Scroll through to the desired
selection of either 'Default', 'Nonvol', or 'BootP' and press the Enter Key.
The Default Mode pre-loads the SNMP parameters with preset values. The Nonvol Mode uses
the same parameters previously stored in Non Volatile Memory. The BootP Mode uses
Bootstrap Protocol to download the following parameters from a Boot Server: Modem IP
Address, Server Ethernet Address, Server Host Name, Router IP Address, and the IP Address
Mask.
The Router IP Address and the IP Address Mask are retrieved from the vendor-specific area of
the BootP Reply Packet.
4.4.2.7 Setting the Modem IP Address
While the SNMP Mode is set to Test, select '33' from the Configuration Screen and type in the IP
Address in decimal dot notation and press the Enter Key.
example - 192.168.0.35
4.4.2.8 Setting the Server IP Address
Select '35' from the Configuration Screen and type in the IP Address in decimal dot notation and
press the Enter Key.
