The BMC web application is available via TLS-secured (https) access either directly through port 443 or indirectly through port 80 to 443. ACL rules are not applicable to prevent unsecured (http) access. A sample X.509 certificate which is a copy of the BMC, and EMA certificates are shipped along with the SBC shipment. The size of this certificate is 2,048 bits.

The BMC uses the common local certificate store of the SBC (used also for SIP/TLS) rather than having its own separate certificate store. Certificate with RSA keys up to 4,096 bits are supported. However, Sonus recommends using 2,048 bit certificates.

Enter the following URL in the browser to access the SBC BMC GUI:

https://<BMC IP Address>

where BMC IP Address is the IP address of the BMC GUI.

The BMC also provides the interface which uploads the self-signed certificate to replace the sample X.509 certificates.

Note

The SBC is delivered with sample self-signed X-509 certificates. Please be aware that even though these sample certificates allows you to use HTTPS to access the SBC from BMC, or EMA interfaces, using this protocol with the sample certificates is not a truly secure access method. If your organization requires a more secure access, refer to Generating PKI Certificates. 

 

Note

The SBC supports a maximum of 4,096 TLS certificates/CAs (both local and remote).

The following procedure describes how to upload self signed certificates using BMC:

  1. Log on to the SBC BMC using the IP address configured in the previous section.
    The SBC BMC main screen appears.
