IOS SMI para EMI

Tenho 02 switchs 3750 com as características destacadas abaixo. A pouco tempo descobri que preciso de algumas features que a SMI não possui. Minha pergunta é:
Quais as questões físicas (hardware) e legais (licença) caso eu consiga um IOS EMI e queira aplicar nestes switchs ??

Obrigado.
