Hi James,
It's possible to generate a new self-signed certificate using the two commands below:
- WAAS# crypto generate self-signed-cert waas-self.p12 rsa modulus 1024
- WAAS(config)# crypto ssl services global-settings machine-cert-key waas-self.p12
Once the new certificate has been generated, the alarm should go away
For your information, this issue is tracked under bug id CSCte05426
Regards
Daniel
