Third-party optics on HPE FlexFabric 5700: no allow command, only transceiver phony-alarm-disable
0
The poster asked whether third-party optics can be used in an HPE FlexFabric 5700 40XG 2QSFP+ (JG896A) and whether the ProVision command allow-unsupported-transceiver exists on it. The answer clarified how Comware differs from ProVision: there is no allow-list of supported transceivers, so unlisted modules generally work, but the device repeatedly logs traps for any module whose vendor name is not HPE, and support is refused for issues on such links.

Comware has no allow-unsupported-transceiver; the relevant command is transceiver phony-alarm-disable, which only suppresses the warnings. It was added to the 5700 in release F2417 (feature: transceiver module alarm suppression).
An HPE employee noted that even legitimate HPE-sold transceivers are sometimes flagged as third-party due to software bugs or wrongly set module registers, which is the intended use of the suppression command.
