CTRON-DCM-MIB

Description: Manages Cabletron DCM (Device Configuration Manager) for centralized device configuration and provisioning.

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.

CTRON-DCM-MIB is a small vendor-specific Cabletron Systems MIB, part of the ctDcm branch under the Cabletron enterprise tree, that exposes a single control object, dCMMode, for managing Distributed Chassis Management on Cabletron modular hub/switch systems. The dCMMode object is a read-write integer indicating whether a module operates in standalone(0) mode -- supporting only its own module-level MIBs -- or distributed(1) mode, in which it shares management information with other modules in the chassis and presents a unified view via a chassis IP. Rather than exposing hardware sensors or traffic counters, it is a configuration-state MIB whose value reveals how chassis-wide management visibility is currently architected. Monitoring it helps confirm that a module is correctly participating in (or intentionally isolated from) the chassis-wide management view, which affects whether other per-module MIBs are reachable through the chassis IP. It depends on the broader group of DCM-related MIBs in the ctDcm branch, and it is deployed on Cabletron/Enterasys modular chassis systems alongside those companion MIBs -- the CTRON-DCM-MIB MIB is what administrators load to check this mode setting.

An operator polls dCMMode on each module in a Cabletron chassis to confirm it is set to distributed(1); a module unexpectedly reporting standalone(0) would indicate it has dropped out of the chassis-wide management view and its per-module data may not be visible through the chassis IP.

Manages distributed chassis management mode for Cabletron network switches.
