What is the purpose of the DOCSIS Configuration File?
A DOCSIS Configuration File is required for all DOCSIS cable modems and provides settings for the
cable modem. Settings in the DOCSIS file for the XP-DSM are optional and include setting SNMP
security (community strings) for the modem and for upgrading the firmware for the modem.
In Single IP Mode, if the community strings are not set in the DOCSIS Configuration File, only the
power supply SNMP MIB varbinds (enterprise.5591 and enterprise.926) will require community
strings AlphaGet (Read) and AlphaSet (Read/Write) default. However if the cable modem community
strings are set in the DOCSIS Configuration File they will override the DSM defaults. See
.
Is there a way to set options on multiple XP-DSMs without visiting each site?
The DSM Setup File allows automated distribution of communications, power supply, and firmware
upgrade options to every XP-DSM on the network. See
.
Can the XP-DSM be set to generate SNMP traps?
The XP-DSM supports the SNMP alarms defined in the SCTE-HMS Property MIB. See
.
What if traps are not being received by the SNMP manager?
•
Disable personal firewalls on computer receiving traps.
•
Disable firewall clients in network interface properties, e.g. Check Point SecuRemote.
•
Ensure DSM trap table is populated – atiMgmtSnmpTrapTable OID: 1.3.6.1.4.1.926.1.3.1.1.
•
Ensure SCTE-HMS propertyTable and discretePropertyTables are configured to sent traps on
desired power supply conditions.
•
Ensure port 162 is not blocked or filtered.
How is the cause of a psMajor Alarm determined?
With most transponders a site visit is required to look at the LCD on the XM2. With the XP-DSM,
however, the cause of a psMajor alarm can be determined by looking at the ‘DISCRETES’ table either
through the XP-DSM Web page or through SNMP MIB atiCibDiscTable. The XM2 parameter that
caused the alarm will have a value of ‘ALARM’. See
How is firmware upgraded on the XP-DSM?
The XP-DSM uses TFTP to upgrade the power supply monitoring (HMS) firmware and is independent
of the modem firmware. The DSM Setup File can be used to automate the upgrade, or an Alpha-
provided software application can be installed and managed from any Windows or Sun Solaris server
on the XP-DSM’s network. See
