Захотелось подружить Cisco 4948 c 122-54.SG и древний Picolight SFP модуль, по злой рок в виде
C4K_CHASSIS-3-SFPINTEGRITYCHECKFAILED:SFP
не давал этим двум славным железкам слиться в экстазе. Подружить негодников удалось 3мя волшебными командами:
service unsupported-transceiver no errdisable detect cause gbic-invalid errdisable recovery cause gbic-invalid
и, аллелуя!
