<br>

<br><font size=2 face="sans-serif">I am sending this e-mail for a colleague.

He states:</font>

<br>

<br><font size=2 face="sans-serif">Clarification is needed on test case

5.1.12 of the IPSec v1.1.0 test suite. &nbsp;The title reads</font><font size=3>&quot;5.1.12

ICV calculation (ESN), ESP=3DES-CBC HMAC-SHA1&quot;. &nbsp;</font><font size=2 face="Arial">

I need clarification that the 'ESN' in the title refers to Extended Sequence

Number function being tested.  The script and packet information included

with the test case does not help to clarifiy.  If this does imply

that ESN is to be tested for 5.1.12, that would seem to contradict wording

in RFC4306 which says that ESN must be negotiated by a SA negotiating protocol

(i.e. IKE).</font>
