Chromatis-MIB

Root enterprise OID tree for Chromatis Networks Metropolis metro optical systems, defining subtrees for hardware, ATM interfaces, performance management, fault management, and protection

Chromatis-MIB is the root enterprise OID tree for Chromatis Networks' Metropolis metro optical transport systems (later acquired by Lucent/Nokia), defining top-level subtrees for hardware (chrComHW), interfaces (chrComIf), and broader product organization (chrCommon, chrProducts) alongside dedicated areas for performance and fault management. It belongs to the metro optical/carrier transport equipment category and, while structured as a root/registration module, its subtree naming indicates coverage extending into ATM interfaces and both performance and fault management data for optical transport nodes. Objects such as chrComSwVersion and chrComConfigVersion point to direct software/firmware version and configuration version tracking, useful for confirming a node's running software build and configuration state, while the referenced performance- and fault-management subtrees imply support for monitoring alarms and traffic performance counters on optical interfaces. As a metro optical product line, it likely depends on standard interface and ATM MIB conventions for underlying transport data. It is deployed in carrier metro networks running legacy Chromatis Metropolis optical transport equipment, and engineers who download Chromatis-MIB today typically do so to keep supporting these aging nodes since the original vendor no longer exists.

An administrator could poll chrComSwVersion and chrComConfigVersion under the chrComHW/chrComIf subtrees to confirm which software build and configuration revision a Chromatis Metropolis node is currently running, useful when validating a firmware upgrade across a metro ring. The chrComIf subtree would expose ATM interface status on the optical transport node, letting an operator detect interface faults or misconfiguration. Deeper fault- and performance-management subtrees (implied by the module's structure) would be where alarm and traffic-counter polling actually occurs, though this top-level module mainly organizes those areas.
