Syslog CA

This topic describes about the third-party certificates for RASlog service (syslog from SLX).

EFA is shipped with default certificates. These are self-signed and the same certificates are used for listening to the syslog messages received from SLX.

$ efa inventory device register --ip=10.x.x.x --username=admin --password=password

The syslog certificate on the device is the default CA the EFA contains.

The enhancement updates RASlog service to use the custom certificates that EFA servers use. The certificate CLI on EFA contains new parameter, which enables you to upload CA.

$ efa certificate server --certificate=my_server_162.pem --key=my_server_162.key --cacert=ca-chain.pem 
Please wait as the certificates are being installed...

If there are already registered devices, then the syslog certificate is updated on these devices.

If you do not provide any CA certificate, the default certificates of EFA are used.
