Can't create Client SSL profile with self signed ECC certificate.

Hi!

I'm trying to create Client SSL Profile with self signed ECC certificate as described below:

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-11-5-1/11.html

First I created ECC self signed certificate and it works well, then I'm trying to create Client SSL profile using that certificate and on this point it do not works and I'm getting following error:

010717e3:3: Client SSL profile must have RSA certificate/key pair.

Please help.

Thank you!
