3.4 The DSM Setup File
The DSM Setup File, atidoc01.cfg, is an optional type-length-value (TLV) formatted le
similar to the modem’s DOCSIS Conguration File that distributes custom Alpha MIB settings
to all XP-DSMs on a network. Unlike the DOCSIS Conguration File, the DSM Setup File
is made up only of type 11 entries, OIDs supported by the transponder through the Alpha
MIB. The XP-DSM is programmed to check for this le at startup and after every 24 hours of
operation (congurable) and update with the settings dened.
The IP address of the TFTP server where atidoc01.cfg is located must be dened in the
modem’s DOCSIS Conguration File using the parameter docsDevSwServer. This entry
should be dened as type 21 (Software Upgrade TFTP server) and not type 11 (misc. SNMP
entries).
If a DSM Setup File is not used, the transponder will retain its default settings (see Section
3.3) until they are changed manually with a MIB browser or a local computer connected to the
XP-DSM’s local port (see Sections 6.2, 4.0).
Some common parameters set in the DSM Setup File are:
• Switching to Dual IP Mode.
• Setting transponder community strings in Dual IP Mode, see Section 3.4.3.
• Upgrading transponder rmware, see Section 5.2.
• Disabling or enabling the transponder’s Web server.
• Enable ‘Trap on Normal’, see Section 6.3.
• Setting SNMP trap addresses, see Section 6.3.
• Setting power supply parameters (Alpha recommends contacting your Alpha
representative before changing power supply settings).
3.4.1 Building the DSM Setup File
To build a DSM Setup File, enter SNMP parameters and values from the Alpha MIB
(see Section 6.2) inside a TLV le using a TLV editor.
The entry atiMgmtSysDownloadCfgCheckProgress with the value of 3 is the le
marker that the XP-DSM looks for to begin reading entries and must be the rst entry
in the le.
The DSM Setup File must be named atidoc01.cfg and placed in the root directory of
the TFTP server.
XP-DSM settings are updated according to values dened in this le at startup and
after every 24 hours of operation.
See the example le on the next page.
NOTE:
Most TLV editors will display the parameter name instead of the Object ID if the SNMP MIB le ATI-TABLES-
MGMT-MIB.mib is copied into the installation directory of the TLV editor. This makes the le more readable.
NOTE:
The procedure in this section applies to rmware version 1.08.0 or newer. For an application to upgrade from
earlier rmware versions, go to www.Alpha.com>Broadband>StatusMonitoring>DSM>XP-DSM Downloads.
