Information About Cisco TrustSec FC Link Encryption

</h1>
<a name="wp1072865"> </a><p class="pBody">
Cisco TrustSec FC Link Encryption is an extension of the Fibre Channel-Security Protocol (FC-SP) 
feature and uses the existing FC-SP architecture to provide integrity and confidentiality of transactions. 
Encryption is now added to the peer authentication capability to provide security and prevent unwanted 
traffic interception. Peer authentication is implemented according to the FC-SP standard using the 
Diffie-Hellman Challenge Handshake Authentication Protocol (DHCHAP) protocol. 

</p>
<a name="wp1072866"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Cisco TrustSec FC Link Encryption is currently only supported between Cisco MDS switches. This 
feature is not supported when you downgrade to software versions which do not have the Encapsulating 
Security Protocol (ESP) support.
