Damnit I hate GBICs. Two of these fuckers can look identical but one won't work in a specific switch because it's tagged with the wrong vendor or doesn't support some obscure feature the switch vendor stopped supporting.
@zorinlynx this burns my ass with SFPs (and GBICs before this). Cisco, Arista, Intel, Juniper and others burn their vendor IDs into the SEEPROM on an otherwise bog-standard Avago or Finisar part, and then all except Juniper refuse to work if their vendor ID isn't there. (Juniper just states "non-Juniper" but STILL WORKS)
Intel won't load the module unless I pass an option to use unsupported transceiver. On some Cisco, I can use "service unsupported-transceiver" but I shouldn't need to!
