Hi everybody,

As i say i c'ant discover my IPS device with CSM, i have this message :

I already generate a new rsa key on the ASA FW IOS version 8.4, my login is ok and my password to. i successfully discover the ASA FW but not the IPS module.

ver CSM 4.3.0 service pack2

Thank you for your help.

Note the error message shows the IPS certificate expired last year:

Validity: [From: Tue Dec 07 10:42:59 CET 2010, To: Fri Dec 07 10:42:59 CET 2012]

You'll need to address the issue of the expired certificate on the IPS. If they CSM server cannot communicate securely (which depends on a valid IPS certificate) it will not allow you to proceed.

Hi Marvin,

Thank you for you reply, sorry i didn't understand very well but generate a new rsa key on the ASA is not

not enough.I need to discuss this issue with my boss in order to get new certificate on IPS.

Best regards,

This is a common issue with IPS and is easily fixed.

The IPS uses a self-signed certificate for TLS (Transport Layer Security) protection of its management channels. When an IPS is initialized that self-signed certificate is valid for two years. That certificate is distinct from the ASA RSA key.

To regenerate, please see the procedure described here.

Hi Marvin,

Thank very much, on cli commande i launch a tls generate-key and now the certificate is valide fot two years.

My issue has been resolved thank you for our help.

Best regards,
