HC-PerfHist-TC-MIB

Extends PerfHist-TC-MIB with high-capacity (64-bit) textual conventions for 15-minute and 24-hour performance history data on high-speed interfaces.

HC-PerfHist-TC-MIB is an IETF standards-track MIB (RFC 3705) that supplies high-capacity (64-bit) textual conventions layered on top of the original PerfHist-TC-MIB, intended for performance-history counters on high-speed telecom interfaces where 32-bit counters would wrap too quickly. It defines data types rather than managed objects, so its category of exposed data is limited to reusable counter and interval textual conventions consumed by other performance-monitoring MIBs. It has no direct monitoring role for hardware or software status by itself; its value is entirely in enabling accurate 15-minute and 24-hour interval performance counters (e.g. error seconds, severely errored seconds) in the MIBs that import it, on circuits fast enough to overflow standard counters. It explicitly depends on and extends PerfHist-TC-MIB (RFC 3705) and is commonly imported by SONET/SDH, DS3, and other high-speed interface performance MIBs. It is used wherever high-speed WAN or transport interfaces need standards-based, high-capacity performance history reporting, and any HC-PerfHist-TC-MIB reference found in such an interface MIB signals that the module implements 64-bit counters suitable for circuits fast enough to overflow the original PerfHist-TC types.

This is a textual-conventions-only module with no sample objects of its own; it defines types such as high-capacity 15-minute and 24-hour interval counters that other MIBs (e.g. high-speed SONET/DS3 performance MIBs) import to build their actual PerfCurrentTable/PerfIntervalTable structures. There is no standalone monitoring scenario since it contributes no pollable OIDs directly.
