F5 LTM V11 CRL file uploading Error

Thanks for your responses,

the CRL file size is 11M that contains more or less 269535 revoked certificates. Without placing it in the /config/ssl/ssl.crl path, when I perform the upload via GUI, I don't see at the end of the process the file uploaded in the /config/ssl/ssl.crl, I don't know if it is normal;

I have already though about OCSP which is more update and more efficient but my F5s haven't access to internet and I have no local OCSP Server available in my in frastructure.

With CRLDP, I have seen that the menu to configure an CRLDP server is available but i don't know if it really works; I'm not sure because it's reported in the APM feature too. So I guess or I don't khnow if it is reliable.

Is there anyway to ensure that CRLDP Works really on LTM and where does the cached version of the downloaded CRL file is stored in this case ? does the uploading process of the CRL from the CRL Distribution Point begin when the CRLDP Configuration is completed or is it necessary to performe an authentification so as to lauch the upload process ?
