> # About IKE

> IKE automatically negotiates IPsec security associations and generates keys for all switches using the IPsec feature. Specifically, IKE provides these benefits:

> - Allows you to refresh IPsec SAs.
> - Allows IPsec to provide anti-replay services.
> - Supports a manageable, scalable IPsec configuration.
> - Allows dynamic authentication of peers.

> IKE is not supported on the Cisco Fabric Switch for HP c-Class BladeSystem and the Cisco Fabric Switch for IBM BladeSystem.
