Platform and line card
Confirm Catalyst or Nexus model, supervisor, line card, ASIC generation and port cage.
Compatibility engineering brief
Cisco Optical Module Compatibility Engineering
A Cisco-oriented code is only one layer of approval. The host tuple, physical link, FEC policy, telemetry and tested sample define the actual result.
Cisco platforms can read a programmed identity and still behave differently across Catalyst and Nexus families. Hardware generation, ASIC, line card and software policy belong in the approval record before a sample is chosen.
A stable link requires more than EEPROM recognition. Lane mode, optical standard, connector path, negotiated FEC, DOM thresholds and sustained error counters must agree with the named port role.
MingApex coordinates sourcing, coding and independent QC from China. It does not claim Cisco manufacture or affiliation; the commercial proposal identifies the exact third-party configuration and evidence scope.
01 / Scope record
Freeze the exact approval record before selecting a code
Record the entire Cisco host tuple, not only a switch family or OEM part number.
| Required field | What to record | Why it changes the result |
|---|---|---|
| Host model / hardware | Exact Cisco platform: for example Catalyst 9300/9500 or Nexus 3000/9000, including chassis, supervisor and line-card identifiers. | Support can differ by chassis, line card, ASIC and port cage. |
| Software version | Exact IOS XE or NX-OS release and any relevant transceiver-service or unsupported-transceiver policy. | Allow-lists, alarms, breakout and FEC behaviour can change by release. |
| Port mode | Native speed, breakout map, lane allocation and whether the port is switch-facing, server-facing or uplink. | A physical cage may expose several mutually exclusive speed or breakout modes. |
| FEC policy | Configured and negotiated no-FEC, FC-FEC or RS-FEC state for the exact line rate and optic family. | The wrong FEC policy can leave a recognized module without a stable link. |
| DOM / DDM | Cisco CLI recognition, temperature, voltage, bias, Tx/Rx power, threshold visibility and alarm state. | Recognition alone does not prove valid telemetry, thresholds or alarm reporting. |
| Coding identity | The approved Cisco-oriented vendor name, part-number string, serial format and EEPROM profile. | Vendor fields and part-number identity must match the approved coding profile. |
| Sample boundary | One serialized sample tested on the named Cisco host, port and software baseline; no automatic extension to other platforms. | A result belongs to the tested unit and named host tuple unless the scope says otherwise. |
02 / Technical checks
What must be checked on the named platform
The review separates recognition, link operation and production repeatability. Passing one layer does not silently approve the others.
IOS XE / NX-OS policy
Record the software release, transceiver policy and relevant alarm behaviour.
Speed and breakout
Verify native mode, lane map and supported breakout on the exact port.
FEC state
Capture configured and operational FEC; do not infer it from line rate alone.
DOM and alarms
Read all available telemetry and compare values with thresholds under load.
Traffic stability
Observe link flaps, CRC/FEC counters and temperature for a defined test period.
03 / Catalogue anchors

These products are technical starting points. A product page or programmed code is not evidence of blanket host support.
04 / Validation
Named-host sample and production-release workflow
The sample plan should prove the intended Cisco port state and preserve enough identity data to release the later production lot.
- 1
Freeze the host tuple
Record the exact device, chassis or line card, software release, port identifier and intended link role for Cisco compatibility.
- 2
Confirm physical and protocol fit
Match form factor, line rate, reach, wavelength, fibre, connector, breakout mode and required FEC before coding.
- 3
Program and identify the sample
Lock vendor fields, part number, serial format, DOM profile and sample identity so the tested unit can be traced.
- 4
Test on the named host
Record recognition, link state, DOM, alarms, error counters, FEC status and traffic stability for the stated software baseline.
- 5
Bridge sample approval to the lot
Release production only when coding identity, optical checks, labels and change-control records remain tied to the approved sample and order line.
05 / Decision patterns
Common approval scenarios and their limits
Approval paths differ between campus access, data-centre fabric, long-reach uplinks and high-speed breakout.
Catalyst access refresh
Keep the exact switch SKU and IOS XE baseline with 1G/10G port behaviour and DOM visibility.
Nexus fabric uplink
Validate lane mode, FEC and sustained counters for 100G/400G leaf–spine links.
Breakout migration
Prove the parent port and every child lane on the named cable/optic combination.
Long-reach link
Confirm optical budget and alarms in addition to Cisco recognition.
06 / Buyer evidence
Compatibility evidence pack
Use these redacted records to define what must be captured for the exact host, sample and order line.
07 / Risk control
Failure modes to remove before production approval
Family-level approval
“Nexus compatible” is too broad when line cards and ASIC generations differ.
Recognition-only testing
A readable part number does not prove traffic stability or correct FEC.
Software drift
A later IOS XE or NX-OS release may change warnings or port behaviour.
Sample-to-lot identity drift
Coding or component changes can invalidate the original host result.
08 / Buyer questions
Compatibility-specific questions
Does Cisco-oriented coding guarantee compatibility?
No. It may support recognition, but the named hardware, software, port, FEC, DOM and traffic test define approval.
Can a Nexus test approve Catalyst ports?
No automatic extension is made. The result stays with the tested Cisco host tuple unless a documented matrix proves additional hosts.
What must be captured from CLI?
Record inventory/recognition, operational speed, FEC, DOM values, alarms and relevant error counters before and during traffic.
Can the same sample identity be repeated?
Only when coding, labels, optical specification and change-control requirements are locked to the approved sample.
