OVLOCKEX Violation

Supports only Extreme transceivers

Status: Current — The violation is standing.

Extreme Networks networking equipment often includes SFP, SFP+, or similar transceiver slots. These accept only Extreme-made transceivers, despite the fact that these are standard components.


There appear to be indications that Extreme have reneged on this practice in newer models. Older devices remain affected. However, see this.


  • The transceiver's EEPROM can be reprogrammed to have Extreme's vendor ID, causing it to be accepted. There are mail-in services which will perform this change, for a fee.
