Multiple RSA Key-Pair and Identity CA Support

</h1>
<a name="wp1072875"> </a><p class="pBody">
Multiple identity CA support enables the switch to enroll with more than one trust point. This results in 
multiple identity certificates; each from a distinct CA. This allows the switch to participate in IPsec and 
other applications with many peers using certificates issued by appropriate CAs that are acceptable to 
those peers.

</p>
<a name="wp1072876"> </a><p class="pBody">
The multiple RSA key-pair support feature allows the switch to maintain a distinct key pair for each CA 
with which it is enrolled. Thus, it can match policy requirements for each CA without conflicting with 
the requirements specified by the other CAs, such as key length. The switch can generate multiple RSA 
key-pairs and associate each key-pair with a distinct trust point. Thereafter, when enrolling with a trust 
point, the associated key-pair is used to construct the certificate request.
