3.2 The DOCSIS Conguration File
3.2.4 Proprietary Conguration File ‘idhdoc04.cfg’
The IDH4 Series will attempt to download a TLV-formatted le ‘idhdoc04.cfg’ from the modem’s
provisioning TFTP server at start up and every 24 hours thereafter. The idhdoc04.cfg proprietary
conguration le is optional and provides an alternative method to the modem’s DOCSIS conguration
le for deploying Alpha proprietary SNMP MIB parameters to eld-installed IDH4 Series transponders.
The idhdoc04.cfg le 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
conguration le.
To build the idhdoc04.cfg le, enter the desired SNMP OIDs and values from the Alpha MIB into a TLV
le as TLV type-11 entries using a TLV editor (see sample entries below). The IDH4 Series proprietary
conguration Setup le must be named “idhdoc04.cfg” and placed in the root directory of the TFTP
server. IDH4 settings are updated according to values dened in this le 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
conguration le (see Section 3.2, The DOCSIS Conguration File). Alpha-proprietary parameters may
also be set through the modem’s DOCSIS conguration le, eliminating the need for the idhdoc04.cfg
proprietary conguration le.
NOTE:
3.2.5 Changing Default idhdoc04.cfg Download Settings
By default the IDH4 Series will download the idhdoc04.cfg le 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 conguration le.
