ETH-OPT-MIB

Description: Monitors Ethernet optical interface parameters including signal quality and physical layer performance.

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.

ETH-OPT-MIB's existing short description characterizes it as monitoring Ethernet optical interface signal quality, but the only object names available in this data — cdx6500PCTPortProtocolGroup and cdx6500PSTPortProtocolGroup — instead resemble per-port protocol-group configuration entries on a 6500-series chassis switch, suggesting the short description may not accurately reflect this module's actual object tree (or the sample only captures an unrelated fragment). If the short description is accurate, the module would expose physical-layer optical metrics such as signal strength or link errors; the sample objects instead point toward per-port protocol/connection-type configuration. Either way, the general theme is physical/data-link layer interface status — whether framed as optical signal quality or per-port protocol group state — used to catch degraded links or misconfigured port settings. The naming pattern suggests a dependency on or parallel to standard IF-MIB interface-level conventions for per-port polling. It would be deployed on a managed, chassis-based Ethernet switch platform (the '6500' naming suggests a specific chassis line) where per-port physical/protocol-layer status is tracked via SNMP. Engineers can download the ETH-OPT-MIB file directly to load it into their MIB browser.

The available sample_objects (cdx6500PCTPortProtocolGroup, cdx6500PSTPortProtocolGroup) don't match the short description's 'optical signal quality' framing — they read as per-port protocol-group configuration entries on a 6500-series chassis switch — so rather than invent an optical-signal monitoring scenario, the honest read is that an admin would poll these groups to check which protocol/connection type is configured on each port, flagging a mismatch if a port's protocol group doesn't match its expected link type.
