Description: Extends RMON for high-capacity networks by adding 64-bit counter support to the RMON-1 and RMON-2 statistics tables.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring HC-RMON-MIB with a free 30-day trial of IPNetwork Monitor.
What Is HC-RMON-MIB?
HC-RMON-MIB (High Capacity RMON) is a vendor-neutral IETF standards MIB that extends the classic RMON-1 (RFC 2819/RFC 1513) and RMON-2 (RFC 2021) remote monitoring frameworks with 64-bit counters suitable for high-speed links. It exposes traffic and statistics data such as media-independent packet counts, drop events, and overflow/high-capacity counter pairs used to reconstruct full 64-bit values from the original 32-bit RMON counters. Rather than hardware environmental sensors, its monitoring value lies in tracking interface throughput and packet-loss behavior at gigabit and higher speeds, helping operators detect dropped frames, counter wraps, or overflow conditions that indicate congestion or probe malfunction. It explicitly augments and depends on RFC 2819, RFC 1513, and RFC 2021 (RMON-1 and RMON-2), and is typically implemented alongside those base MIBs rather than standalone. It is commonly deployed on RMON-capable probes, switches, and routers monitoring high-bandwidth network segments. Engineers implementing or auditing this functionality typically reference the HC-RMON-MIB RFC/standard documentation for the authoritative specification.
IPNetwork Monitor allows you to monitor SNMP objects defined in HC-RMON-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
- RMON probes
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- high-speed switches/routers
Monitoring Examples
An operator would poll mediaIndependentTable/mediaIndependentEntry rows indexed by mediaIndependentIndex to read mediaIndependentInHighCapacityPkts and mediaIndependentOutHighCapacityPkts, combining them with the base RMON overflow counters (mediaIndependentInOverflowPkts, mediaIndependentOutOverflowPkts) to compute true 64-bit packet totals on a 10G+ link. A rising mediaIndependentDropEvents or mediaIndependentDroppedFrames count alongside stable input rates would flag probe resource exhaustion or interface congestion. The hcRmonMIBCompliances and hcRmonMIBGroups objects define conformance rather than runtime data.
What Can Be Monitored
- high-capacity inbound/outbound packet counts
- packet drop events
- dropped frame counts
- counter overflow tracking
- per-interface traffic statistics

| C64 etherStatsHighCapacityOctets | 1.3.6.1.2.1.16.1.7.1.4 | Counter64 | read-only | The total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets). If the network is half-duplex Fast Ethernet, this object can be used as a reasonable estimate of utilization. If greater precision is desired, the etherStatsHighCapacityPkts and etherStatsHighCapacityOctets objects should be sampled before and after a common interval. The differences in the sampled values are Pkts and Octets, respectively, and the number of seconds in the interval is Interval. These values are used to calculate the Utilization as follows: Pkts * (.96 + .64) + (Octets * .08) Utilization = ------------------------------------- Interval * 10,000 The result of this equation is the value Utilization which is the percent utilization of the ethernet segment on a scale of 0 to 100 percent. This table is not appropriate for monitoring full-duplex ethernets. If the network is a full-duplex ethernet and the mediaIndependentTable is monitoring that network, the utilization can be calculated as follows: 1) Determine the utilization of the inbound path by using the appropriate equation (for ethernet or fast ethernet) to determine the utilization, substituting mediaIndependentInPkts for etherStatsHighCapacityPkts, and mediaIndependentInOctets for etherStatsHighCapacityOctets. Call the resulting utilization inUtilization. 2) Determine the utilization of the outbound path by using the same equation to determine the utilization, substituting mediaIndependentOutPkts for etherStatsHighCapacityPkts, and mediaIndependentOutOctets for etherStatsHighCapacityOctets. Call the resulting utilization outUtilization. 3) The utilization is the maximum of inUtilization and outUtilization. This metric shows the amount of percentage of bandwidth that is left before congestion will be experienced on the link. |

| OID mediaIndependentDataSource | 1.3.6.1.2.1.16.21.1.1.2 | OBJECT IDENTIFIER | read-create | This object identifies the source of the data that this mediaIndependent entry is configured to analyze. This source can be any interface on this device. In order to identify a particular interface, this object shall identify the instance of the ifIndex object, defined in RFC 1213 and RFC 2233 [16,17], for the desired interface. For example, if an entry were to receive data from interface #1, this object would be set to ifIndex.1. The statistics in this group reflect all packets on the local network segment attached to the identified interface. An agent may or may not be able to tell if fundamental changes to the media of the interface have occurred and necessitate a deletion of this entry. For example, a hot-pluggable ethernet card could be pulled out and replaced by a token-ring card. In such a case, if the agent has such knowledge of the change, it is recommended that it delete this entry.
