3.2 The DOCSIS Configuration File
3.2.4 Proprietary Configuration File ‘idhdoc04.cfg’
The IDH4 Series will attempt to download a TLV-formatted file ‘idhdoc04.cfg’ from the modem’s
provisioning TFTP server at start up and every 24 hours thereafter. The idhdoc04.cfg proprietary
configuration file is optional and provides an alternative method to the modem’s DOCSIS configuration
file for deploying Alpha proprietary SNMP MIB parameters to field-installed IDH4 Series transponders.
The idhdoc04.cfg file should be used if the following conditions are true:
1. Non-default settings, such as SNMP Trap Destination Addresses need to be distributed to all
IDH4 Series transponders.
2. The operator does not desire to place Alpha-proprietary parameters into the modem’s DOCSIS
configuration file.
To build the idhdoc04.cfg file, enter the desired SNMP OIDs and values from the Alpha MIB into a TLV
file as TLV type-11 entries using a TLV editor (see sample entries below). The IDH4 Series proprietary
configuration Setup file must be named “idhdoc04.cfg” and placed in the root directory of the TFTP
server. IDH4 settings are updated according to values defined in this file at start up and after every 24
hours of operation.
Sample idhdoc04.cfg Entries:
Network Access Control (3) [Len = 1]: 1
SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.1 / 10.20.30.40
SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.2 / 10.20.30.50
SNMP MIB Object (11) [Len = 23]: atiMgmtSysTamperPolarity.0 / 1
The recommended method for setting the SNMP trap address(es) is through the modem DOCSIS
configuration file (see Section 3.2, The DOCSIS Configuration File). Alpha-proprietary parameters may
also be set through the modem’s DOCSIS configuration file, eliminating the need for the idhdoc04.cfg
proprietary configuration file.
NOTE:
3.2.5 Changing Default idhdoc04.cfg Download Settings
By default the IDH4 Series will download the idhdoc04.cfg file from the provisioning TFTP server
every 24 hours. However, these settings may be adjusted per the tables below by placing the
respective SNMP varbinds into the modem’s DOCSIS configuration file.
