What Is COM21-HCXALM-MIB?
COM21-HCXALM-MIB is the alarm-management MIB for Com21's ComController HCX platform, an early cable-modem termination system used by cable operators for broadband data services. Its scope is fault/alarm notification for the ComController chassis and the cable modem links it serves, rather than configuration or interface counters. It is used primarily to monitor hardware and connectivity faults — chassis or card failures and degraded modem link conditions on the HCX platform — though the specific object names were not captured for this module. It likely depends on Com21's base ComController system MIB for chassis/card inventory context that its alarms reference. It is deployed at legacy cable operator head-end sites running Com21 ComController HCX cable modem termination systems. COM21-HCXALM-MIB SNMP monitoring in practice would involve either polling an alarm table or receiving traps to detect chassis, card, or cable-modem link faults on the HCX platform.
IPNetwork Monitor allows you to monitor SNMP objects defined in COM21-HCXALM-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 ComController HCX cable modem termination system
- cable operator head-end equipment
Monitoring Examples
No sample objects were captured for this module, so a concrete polling scenario can't be honestly detailed with named objects here; in general, an alarm MIB of this kind would define an alarm table an operator polls, or traps it receives, to detect chassis, card, or cable-modem link faults on the Com21 HCX platform.
What Can Be Monitored
- chassis/card alarm conditions
- cable modem link fault alarms

FAQ
What is COM21-HCXALM-MIB used for at a cable head-end running Com21 ComController HCX equipment?
It's the alarm-management MIB for the ComController HCX cable-modem termination platform, focused on fault and alarm notification rather than configuration -- used to monitor chassis or card failures and degraded cable-modem link conditions on the HCX system.
How would an operator use COM21-HCXALM-MIB day-to-day?
By polling its alarm table or receiving its traps, an operator at a cable head-end can detect chassis, card, or cable-modem link faults on the HCX platform, typically cross-referencing the base ComController system MIB for chassis/card inventory context behind each alarm.
