Description: Manages subscriber terminal unit (STU) registration and parameters on COM21 HCX cable systems.
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 COM21-HCXSTU-MIB?
This is a COM21 vendor MIB for their HCX cable broadband platform, specifically managing Subscriber Terminal Units (STUs), the cable-modem-like customer premises endpoints registered against the headend/controller. The module description and sample objects were unavailable in the source data (the accompanying description text actually referenced a different, related COM21 ComPort Control MIB), so specific object names cannot be confirmed, but based on the MIB name and product family it would be expected to expose STU registration state, provisioning parameters, and per-subscriber-unit operational status. Typical monitoring value for this class of module includes registration/online status of each subscriber terminal and basic service parameters, serving as a proxy for subscriber-facing hardware/software health on the HCX access network. It would be deployed alongside other COM21 HCX MIBs (like the ComController/ComPort MIBs) that manage the headend side of the same cable plant. It was used by cable operators running COM21 HCX broadband access equipment. Engineers can download the COM21-HCXSTU-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in COM21-HCXSTU-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
- COM21 HCX cable broadband subscriber terminal unit / headend controller
Monitoring Examples
No sample objects were available for this MIB in the source data, so a concrete polling scenario referencing real object names cannot be responsibly constructed; the module description on file was for a related but distinct COM21 MIB, not this one.

How to Use in IPNetwork Monitor
Example using hcxStuIpCurrArpFiltStat OID:
Select a Com21 HCX subscriber terminal unit (cable modem CPE, legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hcxStuIpCurrArpFiltStat into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. Contains the number of ARP packets from this ComPort dropped due to authentication filtering in the current 15 minute collection period. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

| NTF hcxIncompSwVersion | 1.3.6.1.4.1.1141.4.100 | This trap is issued if the configured sw version (in hcxStuConfSwImage) is not applicable to the hw version/hw options reported by the ComPort. This an event with no clear condition. Only severity is WARNING. | ||
| NTF hcxStuAcqEvent | 1.3.6.1.4.1.1141.4.90 | This trap is issued only when the acquisition trap is enabled via the hcxStuAcqTrapEnable attribute. Severity WARNING. | ||
| INT hcxStuAcqFailInfo | 1.3.6.1.4.1.1141.2.51.1.1.4 | INTEGER | read-only | This attribute provides secondary information related to an ComPort acquisition. If there is a failure in the system that prevents a user from receiving full service, then it will be indicated by this attribute. If an ComPort is unacquired or no problems were encountered then this attribute shall equal noFailure. |
| NTF hcxStuAcqOnlineFail | 1.3.6.1.4.1.1141.4.105 | This trap is issued if an RX card successfully acquires an ComPort, but the ComPort cannot be placed online due to a ComController or ComPort failure. Only severity is WARNING. | ||
| NTF hcxStuAcqRangeFail | 1.3.6.1.4.1.1141.4.104 | This trap is issued if an RX card reports a failure to range a previously acquired ComPort. Note that the ComPort states are defined in the proxy ComPort MIB. This an event with no clear condition. Only severity is WARNING. | ||
| INT hcxStuAcquired | 1.3.6.1.4.1.1141.2.51.1.1.3 | INTEGER | read-only | This attribute defines the acquired state of the ComPort. Note that is state is set once an ComPort can be managed.

The Common Controller download process shall check this value when a download is requested. If this image does not support the hardware specified by the ComPort then an incompatible software version trap shall be generated. It is then up to the user to correct this field. When this field is set, the agent shall check if there is an image of the specified type loaded. If this is not the case then a unavailable software version trap shall be generated. Again, it is the responsibility of the user to ensure that the required image is downloaded. The image identifier shall be represented by 4 numbers deliminated by periods. i.e. a.b.c.d. Each number shall have a value between 0 and 255. This allows storage within a single (four byte) word. |
