En esta página, se describe cómo modificar MACsec para el comportamiento de falla de apertura de Cloud Interconnect.
Puedes optar por habilitar MACsec para Cloud Interconnect con un comportamiento de falla abierta. El procedimiento del tipo fail-open significa que si los routers de conexión de Google no pueden establecer una sesión de acuerdo de clave MACsec (MKA) con tu router, la conexión de Cloud Interconnect permanece operativa con tráfico no encriptado. La configuración predeterminada descarta todo el tráfico si no se puede establecer una sesión de MKA con tu router.
Solo puedes cambiar el comportamiento de la conmutación por error de MACsec con Google Cloud CLI.
Habilita el comportamiento de falla abierta
Verifica que no haya tráfico en tu conexión de Cloud Interconnect antes de habilitar MACsec para Cloud Interconnect con comportamiento de falla.
Si tienes habilitado el comportamiento de apertura de errores en MACsec para Cloud Interconnect, puedes inhabilitarlo más adelante. Después de que el comportamiento de falla abierta se inhabilita, si los routers de conexión de Google no pueden establecer una sesión de acuerdo de clave MACsec (MKA) con tu router, la conexión descarta todo el tráfico.

Fail-open means that if Google's edge routers can't establish a MACsec\nkey agreement (MKA) session with your router, then the Cloud Interconnect\nconnection remains operational with unencrypted traffic. The default setting\ndrops all traffic if an MKA session can't be established with your router.\n\nYou can change MACsec fail-over behavior only by using the Google Cloud CLI.\n| **Warning:** To avoid unintentionally passing unencrypted traffic, we recommend that you use the default setting for production traffic, and use fail-open behavior only for testing and troubleshooting.\n\nEnable fail-open behavior\n-------------------------\n\nVerify that there is no traffic on your Cloud Interconnect connection before\nenabling MACsec for Cloud Interconnect with fail-open behavior.\n**Important:** When you enable fail-open behavior on your Cloud Interconnect connection, you must temporarily disable MACsec on your Cloud Interconnect connection. The connection temporarily experiences packet loss as a result. To avoid disruption to your network, verify that there is no traffic on your Cloud Interconnect VLAN attachments before disabling MACsec for Cloud Interconnect.
