Hola Juan, Los teléfonos los puedes autenticar bien por 802.1x (si lo soportan) o bien por MAB (Mac-authentication-bypass). En este último caso, los puedes dar de alta en directorio activo como usuarios, nosotros lo empleamos con impresoras y funciona muy bien. De todas formas te recomiendo que pruebes a configurar MDA (Multi-Domain-authentication) en el caso que emplees una vlan para la voz y otra para datos (te lo recomiendo), creo que es la mejor opción, ya que con MAB tendrías que modificar los timers de 802.1x para un buen funcionamiento ( nosotros los tenemos modificados). http://d2zmdbbm9feqrf.cloudfront.net/2011/anz/pdf/BRKSEC-2005.pdf De todas formas mira esté post te puede ayudar mucho: https://supportforums.cisco.com/community/netpro/security/aaa/blog/2012/02/16/deploying-8021x-when-workstations-are-connected-behind-ip-phones Un saludo.

Hello, I believe that IOS version doesn't support BFD. The minimum IOS version which supports BFD is 15.2(1)E: BFD: http://www.cisco.com/en/US/docs/switches/lan/catalyst3750x_3560x/software/release/15.2_1_e/configuration/guide/scg3750x.html Cisco: http://www.cisco.com/en/US/products/ps10745/products_installation_and_configuration_guides_list.html 15.2(1)E Configuration Guide: http://www.cisco.com/en/US/docs/switches/lan/catalyst3750x_3560x/software/release/15.2_1_e/configuration/guide/scg3750x.html Best regards.
