> # About Crypto Map Set Interface Application

> You need to apply a crypto map set to each interface through which IPsec traffic will flow. Applying the crypto map set to an interface instructs the switch to evaluate all the interface's traffic against the crypto map set and to use the specified policy during connection or SA negotiation on behalf of the traffic to be protected by crypto.

> You can apply only one crypto map set to an interface. You can apply the same crypto map to multiple interfaces. However, you cannot apply more than one crypto map set to each interface.
