Description: ARRIS DOCSIS cable modem device configuration, registration status, and diagnostics.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ARRIS-CM-DEVICE-MIB?

ARRIS-CM-DEVICE-MIB is an ARRIS Broadband vendor-specific MIB (under arrisProdIdCM) that supplies proprietary management objects for ARRIS DOCSIS cable modem (CM) devices, layered on top of the standard DOCSIS cable modem MIBs. It exposes device-level configuration and identity objects such as arrisCmDevWanIsolationState (controls whether home-network traffic is isolated from the WAN/Internet), arrisCmDevSwImageName and arrisCmDevSwImageBuildTime (currently running firmware image and build date), arrisCmDevProvMethodIndicator (provisioning method: DOCSIS-only, full PacketCable, CPS, GUPI, single-MAC), and arrisCmDevEnableDocsis20 (DOCSIS 2.0 mode toggle requiring reboot). This data is useful for confirming provisioning mode and firmware version on deployed modems and for diagnosing customer-reported connectivity issues caused by WAN isolation being incorrectly enabled. It depends on and complements the standard DOCSIS cable modem MIBs for registration/PHY-layer status, and administrators can download the ARRIS-CM-DEVICE-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ARRIS-CM-DEVICE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

ARRIS DOCSIS cable modems

Monitoring Examples

A support technician polls arrisCmDevWanIsolationState and arrisCmDevProvMethodIndicator on a subscriber's modem to check whether WAN Isolation is stuck in on-ActiveMode(2) or whether the modem provisioned into an unexpected mode like packetCableMinusKDC; an unexpected active isolation state would explain a customer's total loss of Internet connectivity despite DOCSIS registration succeeding.

What Can Be Monitored

WAN isolation state
firmware image name and build time
provisioning method indicator
DOCSIS 2.0 mode enable flag
device configuration setup groups

OIDs

OID symbolic	OID numeric	Type	Access	Description
arrisCmDevMib	1.3.6.1.4.1.4115.1.3.1			This MIB module supplies the basic proprietary (ARRIS-specific) management objects for ARRIS Cable Modem (CM) devices.
arrisCmDevMibObjects	1.3.6.1.4.1.4115.1.3.1.1
arrisCmDevBase	1.3.6.1.4.1.4115.1.3.1.1.1
INT arrisCmDevWanIsolationState	1.3.6.1.4.1.4115.1.3.1.1.1.1	INTEGER	read-write	The object controls the state of WAN Isolation. The meaning of the state is as follows: off-InActiveMode(1) - Data traffic passes freely between the home user's network and the outside network (i.e. the Internet). In this mode, the WAN Isolation state is considered 'InActive'. on-ActiveMode(2) - The home user's network is isolated from the Internet. Data traffic will not pass between the home user's network and the Internet. In this mode, the WAN Isolation state is considered 'Active'.
STR arrisCmDevSwImageName	1.3.6.1.4.1.4115.1.3.1.1.1.2	DisplayString	read-only	The name of the software image currently operating on this device.
STR arrisCmDevSwImageBuildTime	1.3.6.1.4.1.4115.1.3.1.1.1.3	DisplayString	read-only	The build date and time of the software image currently operating on this device.
arrisCmDevCmSetup	1.3.6.1.4.1.4115.1.3.1.1.2
arrisCmDevPermanentSetup	1.3.6.1.4.1.4115.1.3.1.1.2.2
arrisCmDevOperationalSetup	1.3.6.1.4.1.4115.1.3.1.1.2.3
ARR arrisCmDevProvMethodIndicator	1.3.6.1.4.1.4115.1.3.1.1.2.3.2	ArrsCmDevProvMethod	read-write	Indicates the method used to provision the device. This object should only be changed by the configuration file. The following provisioning methods are supported: docsisOnly(0) - DOCSIS-only provisioning fullPacketCable(1) - fully PacketCable compliant provisioning packetCableMinusKDC(2) - same as 'fullPacketCable', except with IPSEC and SNMPv3 disabled cps(3) - compatible with CPS2000 (SNMPv2; IPSEC disabled) gupi(4) - SNMPv2, with no SNMP Informs and IPSEC disabled singleMAC(5) - single config file (SNMPv2, single IP address, single MAC address, no SNMP Informs, IPSEC disabled)
T/F arrisCmDevEnableDocsis20	1.3.6.1.4.1.4115.1.3.1.1.2.3.3	TruthValue	read-write	This object is used to enable/disable DOCSIS 2.0 operation mode. This object is stored into NVRAM and will be operational after the next reboot of the device. Set to true(1) to enable DOCSIS 2.0 operation mode. Set to false(2) to disable DOCSIS 2.0 operation mode. Setting this object to the same value that is already stored in NVRAM will do nothing. After the successful setting of this object, the device will automatically reboot.
arrisCmDevSalesSetup	1.3.6.1.4.1.4115.1.3.1.1.2.4
