<p class=MsoNormal>When configuring encryption, is it acceptable to just use
the MIC, or should an LSC be installed? I have read through the security
guide, and it does state Cisco recommends to use the MIC only for LSC
installation. Reason I am seeking some clarification is, I recently
worked with a TAC engineer on a security issue and he told me to use the MIC
and not worry about using LSCs.<o:p></o:p></p>
