The SBC EMA is enhanced to interface with the common certificate pool using the EMA TLS Profile. The certificates used for HTTPS are exported from the database to the local disk space, and then the EMA TLS Profile facilitates selecting a certificate from the pool and uploading it to the EMA. Two types of files are supported: p12 and pem. The SBC supports SHA-256 for certificate verification.

You can configure only one EMA TLS Profile at any given time.


The SBC supports only one certificate in a local or remote certificate file. For example, a p12 certificate file can contain one local certificate and its privacy key.

You can configure up to 20 client CA certifications (using separate 'set' commands) for an EMA TLS Profile.

PC Java Configuration supports TLS 1.0 only by default. When you disable EmaTlsProfile v1_0, enable the corresponding Java Configuration for TLS support. See the example below for the Windows environment.

After configuring servercert and clientCACert in EmaTlsProfile, an appropriate value must be configured for clientAuthMethod in OAM > EMA to enable client SSL verification.

To enable TLS support in Windows:

  1. Click Start and enter "Java Control Panel" in the Search field.
  2. Launch the Java Control Panel program.
  3. From the Java Control Panel, select Advanced tab.
  4. Check both "Use TLS 1.1" and "Use TLS 1.2" options under Advanced Security Settings section, and click Apply.
  5. Restart your browser for the changes to take effect.

ciphersuite N/AThe EMA TLS Ciphersuite choice for this profile. See Supported ciphersuites for the list of supported ciphersuites.

Supported ciphersuites

The following 12 SSL ciphersuites are supported initially in this feature. This list may change in the future based on requirements.
